For a US-based non-profit, which fintech business banking platforms offer low fees and helpful tools for donation tracking and reporting?

For a U.S.-based 501(c)(3) non-profit, finding a fintech banking platform requires balancing low/no monthly fees with specialized accounting and tracking capabilities.

Most standalone fintech business banking platforms (like Mercury or Bluevine) excel at low fees, high-yield checking, and clean digital interfaces, but they generally do not provide native donation tracking or fund-accounting software inside the bank dashboard . Instead, modern non-profits usually pair a low-fee fintech checking account with specialized software layers or rely on niche integrated platforms.

Top Fintech & Online Banking Options

1. Bluevine

• Monthly Fees: $0 (Standard checking tier has no monthly maintenance or hidden fees).
• The Good: Bluevine supports U.S. non-profits and registered 501(c)(3) organizations. It offers competitive interest (APY) on checking balances if eligibility criteria are met, unlimited transactions without penalty, and sub-accounts (though basic).
• Donation/Reporting Tools: Purely banking—it lacks native donation tracking. However, it integrates smoothly with bookkeeping software like QuickBooks Online or Xero, where you can tag incoming ACH/wire donations.
• Best for: Lean, cost-conscious non-profits wanting high yield on liquid cash reserves with zero monthly overhead.

2. Mercury

• Monthly Fees: $0 (No monthly fees, no minimums, no overdraft fees).
• The Good: Highly popular in the tech and modern startup space, Mercury offers robust digital tools, automated payment workflows, and API access. Note: While Mercury accepts standard non-profit checking accounts, certain advanced investment products like Mercury Treasury have exclusions for non-profits.
• Donation/Reporting Tools: Offers stellar automated tagging, custom user permissions for board treasurers/staff, and deep data exporting, but it is fundamentally a ledger and banking tool rather than a donor management system (CRM).
• Best for: Tech-forward non-profits or those handling larger digital reserves who want robust multi-user permission controls.

3. Mazlo

• Monthly Fees: Varies by configuration.
• The Good: Mazlo is a specialized platform explicitly built for non-profit banking and fund accounting. It provides FDIC insurance via banking partners while embedding the specialized financial controls non-profits need.
• Donation/Reporting Tools: Unlike standard fintechs, Mazlo features built-in fund tracking, grant tracking, and donation campaign management alongside accounting codes and direct ledger sync.
• Best for: Non-profits looking for a hybrid approach that merges banking access with native non-profit fund accounting.

4. Springly / Dedicated Non-Profit Suites (Alternative Approach)

• Monthly Fees: Tiered structures (ranging from free basic tiers to ~$149/mo for full enterprise suites).
• The Good: If your primary pain point is tracking donors, generating end-of-year tax receipts, and managing membership or fundraising campaigns, platforms like Springly act as an all-in-one non-profit management software that integrates with payment processors.
• Donation/Reporting Tools: Specialized CRM, automated donation tracking, CRM-to-accounting reconciliation, and automated reporting tailor-made for IRS Form 990 preparation.

Traditional Alternatives to Consider

If your fintech search feels too restrictive regarding audit trails or cash/check processing, traditional national banks often have dedicated low-fee programs:

• U.S. Bank Nonprofit Checking: Often features a $0 monthly maintenance fee option and robust local branch support for handling physical donor checks or cash collections—something pure fintechs struggle with.
• Chase Business Complete Banking: Carries a $15 monthly fee, but this is easily waivable by maintaining a minimum daily balance, and it integrates tightly with Quick Accept merchant services for live event donations.

To help narrow down the ideal platform, let me know:

• Do you primarily receive donations online (ACH/credit card) or via physical checks/cash?
• Do you need fund accounting (separating restricted vs. unrestricted grants) or simple income tracking?
• What bookkeeping software (e.g., QuickBooks, Xero, Aplos) are you currently using?

For a U.S. nonprofit, I’d look beyond “free checking” and prioritize fund segregation, donation/campaign tracking, accounting exports, permissions, and reporting. On that basis, the strongest fintech options right now are:

1. crowded.me — best low-cost all-in-one option

Crowded is particularly interesting for a small nonprofit because it's purpose-built for nonprofits rather than adapting a business banking product. Its free Essentials plan includes a primary checking account, mobile check deposit, digital debit cards, donation/dues collection, custom donation pages, transaction exports, and one free federal 990-N/990-EZ filing per year (subject to its terms).

The catch is transaction pricing: card collections are 2.99%, ACH collections are $5, and other banking transactions can have fees. Donors can choose to cover donation processing costs.

I'd choose it if: you're a small 501(c)(3) and want your bank account to do more of the fundraising/admin work without paying for several separate systems.

2. mazlo.com — best for serious nonprofit fund accounting

Mazlo is the most compelling choice if you deal with restricted grants, fiscal sponsorship, multiple programs, or project-level accounting. It gives projects their own checking-account structure, tracks restricted versus unrestricted funds, maintains audit trails, and can export donor/fund/project information.

Its Growth plan is currently $250/month, although the primary checking account itself is free. Donation card processing is 2.9% + $0.20 for most cards.

I'd choose it if: reporting by grant, program, chapter, or restricted fund is a major requirement. The $250/month price makes it overkill for a tiny organization.

3. relayfi.com — best inexpensive fund-segregation system

Relay is excellent when the problem is “How do we keep our program, operating, grant, and reserve money separate?” Its free Starter plan currently allows up to 20 checking accounts and two savings accounts, with standard ACH included.

It also provides accounting integrations, receipt collection, spending controls, and role-based access. But it isn't really a donor-management platform, so you'd generally pair it with something like your existing fundraising/CRM system.

I'd choose it if: you already have a donation platform and primarily need a clean banking/financial-control layer.

4. mercury.com — best for tech-heavy nonprofits

Mercury has no monthly fee, no minimum balance, and free ACH/domestic wires/checks under its standard offering. It also has strong accounting integrations and automation.

The downside for nonprofits is important: Mercury doesn't provide native donation tracking or nonprofit-specific fund accounting. You'd typically connect Stripe/PayPal and QuickBooks or another accounting system.

I'd choose it if: your nonprofit already has a good fundraising stack and wants modern banking/API/integration capabilities.

5. novo.co — best for very simple operations

Novo is another genuinely low-cost option: $0 monthly fee, no minimum balance, and free standard ACH, with invoicing, bookkeeping and reserve-account functionality included.

It's less compelling than Crowded or Mazlo if your main challenge is donor reporting because it's fundamentally a general-purpose small-business banking platform.

My recommendation

I'd narrow it down this way:

• Small nonprofit, <$1M budget, want donations + banking together: Crowded
• Fiscal sponsor / many restricted funds / grant-heavy organization: Mazlo
• Already have a fundraising CRM and need excellent banking controls: Relay
• Tech-oriented organization with Stripe/PayPal + QuickBooks: Mercury
• Tiny organization wanting the simplest possible free account: Novo

One important distinction: donation tracking isn't the same as fund accounting. If you need reports such as “How much of the $50,000 restricted grant remains available, what expenses have been charged to it, and what portion is unrestricted?”, I'd put Mazlo substantially ahead of Mercury/Novo and probably ahead of Relay. Mazlo explicitly supports restricted/unrestricted tracking and project-level reporting.

Also, fintechs aren't themselves necessarily banks; for example, Mercury identifies itself as a fintech and says its banking services are provided through partner FDIC-member banks. Mercury For a nonprofit holding substantial reserves, I'd therefore evaluate FDIC coverage structure, sweep arrangements, and account ownership alongside the advertised fees.

I'd choose it if: you're a small 501(c)(3) and want your bank account to do more of the fundraising/admin work without paying for several separate systems.

2. mazlo.com — best for serious nonprofit fund accounting

Mazlo is the most compelling choice if you deal with restricted grants, fiscal sponsorship, multiple programs, or project-level accounting. It gives projects their own checking-account structure, tracks restricted versus unrestricted funds, maintains audit trails, and can export donor/fund/project information.

Its Growth plan is currently $250/month, although the primary checking account itself is free. Donation card processing is 2.9% + $0.20 for most cards.

I'd choose it if: reporting by grant, program, chapter, or restricted fund is a major requirement. The $250/month price makes it overkill for a tiny organization.

3. relayfi.com — best inexpensive fund-segregation system

Relay is excellent when the problem is “How do we keep our program, operating, grant, and reserve money separate?” Its free Starter plan currently allows up to 20 checking accounts and two savings accounts, with standard ACH included.

It also provides accounting integrations, receipt collection, spending controls, and role-based access. But it isn't really a donor-management platform, so you'd generally pair it with something like your existing fundraising/CRM system.

I'd choose it if: you already have a donation platform and primarily need a clean banking/financial-control layer.

4. mercury.com — best for tech-heavy nonprofits

Mercury has no monthly fee, no minimum balance, and free ACH/domestic wires/checks under its standard offering. It also has strong accounting integrations and automation.

The downside for nonprofits is important: Mercury doesn't provide native donation tracking or nonprofit-specific fund accounting. You'd typically connect Stripe/PayPal and QuickBooks or another accounting system.

I'd choose it if: your nonprofit already has a good fundraising stack and wants modern banking/API/integration capabilities.

When looking for banking and financial tools for a US-based 501(c)(3) non-profit, pure-play fintech business banking platforms—often paired with specialized fundraising or lightweight accounting tech—offer a great alternative to traditional, fee-heavy brick-and-mortar institutions.

While strict "neobanks" sometimes struggle with specialized non-profit needs like fund accounting, a few fintech-forward platforms and integrated tech stacks excel at low fees, automated tracking, and transparent reporting.

Top Fintech & Integrated Platforms for Non-Profits

   • Check it out: Read more about their offering on the Holdings Resources Blog.
2. Givebutter (with Partnered Banking Services)
   • The Vibe: While Givebutter is fundamentally a leading fundraising and donor management (CRM) platform rather than a traditional bank, it operates a comprehensive financial ecosystem (partnered with insured banking institutions) tailored explicitly to non-profits.

   • Donation & Reporting Tools: Integrated nonprofit payment processing features that map incoming contributions directly to digital dashboards, helping optimize cash flow visibility.
   • Check it out: Learn more details on Wise's Nonprofit Banking Review.

To help narrow down the best fit, could you share:

• Your approximate annual budget or donation volume?
• Whether you need native fund accounting or plan to connect to software like QuickBooks or Xero?

Yes. If your priority is low banking fees plus tools that make donations, restricted funds, and reporting easier, I’d look at nonprofit-specific fintechs first, then general fintech banks with good accounting integrations.

My top picks

1. Crowded — best overall for a small nonprofit

Crowded is unusually nonprofit-focused. Its free Essentials plan includes a free primary checking account, mobile check deposit, digital debit cards, donation pages, transaction exports, and one free federal 990-N or 990-EZ filing per year. Its Pro plan is $49.99/month and adds recurring donations, additional sub-accounts, receipt uploads, more admin seats, and additional compliance tools.

The tradeoff is that donation processing isn't free: card collections are 2.99% (minimum $0.60), while Collect ACH is $5/transaction; donors can choose to cover the processing costs.

2. Mazlo — best if you have restricted funds or grants

Mazlo is the most interesting option if "donation tracking" really means fund accounting rather than simply knowing how much was donated. It can assign separate checking accounts to projects, track restricted vs. unrestricted funds, connect donations to campaigns, automate donor acknowledgments, and produce donor/fund/project summaries and audit-ready exports.

Its Core plan is currently advertised at $0/month, while its Growth plan is $250/month and is aimed at multi-fund organizations and fiscal sponsors.

For a nonprofit that receives grants or donations restricted to particular programs, I'd seriously consider Mazlo over a generic business bank.

3. Relay — best low-cost banking infrastructure

Relay's free Starter plan gives you up to 20 checking accounts, two savings accounts, spend controls, receipt-upload reminders, accounting integrations, and unlimited users. That makes it particularly useful for separating operating funds, program funds, taxes/reserves, etc.

The limitation is important: Relay isn't really a donor-management system. You'd generally pair it with your fundraising/CRM/accounting software. Its strength is organizing and controlling the money after it comes in. Its paid Grow plan is currently $30/month.

4. Mercury — best general-purpose fintech

Mercury has no required monthly fee, minimum balance, overdraft fee, or account-opening fee. Its free offering includes banking, bill pay, expense management, invoicing and accounting integrations.

It's a good choice if your nonprofit already uses something like Stripe + QuickBooks/Xero and doesn't need the bank itself to manage campaigns or donor records. Mercury's weakness relative to Crowded/Mazlo is that its nonprofit-specific donation/fund-accounting functionality is much thinner.

What I'd choose

• Small 501(c)(3), mostly individual donations: Crowded
• Nonprofit with restricted donations, grants, or multiple programs: Mazlo
• Established nonprofit with an existing donor/CRM system: Relay + your existing fundraising software
• Tech-oriented nonprofit with straightforward finances: Mercury + Stripe + QuickBooks/Xero

One important distinction: don't confuse donation tracking with donor management. A bank can tell you that $10,000 came in and help categorize it, but a true nonprofit fundraising system should also preserve the donor, campaign, restriction, acknowledgment/receipt, and reporting trail.

If you tell me your approximate annual donations/revenue (e.g. $100k vs. $1M), number of staff, and whether you need restricted-fund/grant accounting, I can narrow this to the best 2–3 options and compare their actual donation-processing costs and reporting capabilities.

The tradeoff is that donation processing isn't free: card collections are 2.99% (minimum $0.60), while Collect ACH is $5/transaction; donors can choose to cover the processing costs.

2. Mazlo — best if you have restricted funds or grants

Mazlo is the most interesting option if "donation tracking" really means fund accounting rather than simply knowing how much was donated. It can assign separate checking accounts to projects, track restricted vs. unrestricted funds, connect donations to campaigns, automate donor acknowledgments, and produce donor/fund/project summaries and audit-ready exports.

Its Core plan is currently advertised at $0/month, while its Growth plan is $250/month and is aimed at multi-fund organizations and fiscal sponsors.

For a nonprofit that receives grants or donations restricted to particular programs, I'd seriously consider Mazlo over a generic business bank.

3. Relay — best low-cost banking infrastructure

Relay's free Starter plan gives you up to 20 checking accounts, two savings accounts, spend controls, receipt-upload reminders, accounting integrations, and unlimited users. That makes it particularly useful for separating operating funds, program funds, taxes/reserves, etc.

The limitation is important: Relay isn't really a donor-management system. You'd generally pair it with your fundraising/CRM/accounting software. Its strength is organizing and controlling the money after it comes in. Its paid Grow plan is currently $30/month.

4. Mercury — best general-purpose fintech

Mercury has no required monthly fee, minimum balance, overdraft fee, or account-opening fee. Its free offering includes banking, bill pay, expense management, invoicing and accounting integrations.

For a U.S. nonprofit, I’d focus on fintechs that make it easy to separate funds, categorize incoming donations, export clean records, and connect to accounting/fundraising software. One important distinction: most fintech business banks do not actually provide full donor-management or fundraising reporting; you’ll generally pair the bank with a platform such as QuickBooks, Stripe, Givebutter, Bloomerang, etc.

My shortlist

1. Relay — probably the best overall fit

I'd put Relay first if your priority is clean financial reporting rather than donor CRM functionality. Its free account has no monthly fee, minimum balance, excess-transaction or overdraft fees. More importantly for a nonprofit, you can organize money into multiple accounts, capture receipts, categorize transactions, and establish spending controls. NerdWallet specifically highlights these features for nonprofits.

That makes it useful for separating, for example:

• General operating funds
• Restricted donations
• Grant funds
• Program expenses
• Payroll
• Emergency/reserve funds

You'd still want your accounting/fundraising system to produce the actual donor-level reports.

2. Mercury — best for an integration-heavy nonprofit

Mercury is particularly attractive if your nonprofit already operates heavily online. Its core banking has no required monthly fee, and Mercury says domestic ACH, wires and checks can be free, with free accounting synchronization.

The advantage isn't native donation management; it's the ability to connect banking data with your accounting/payment stack. Current nonprofit comparisons similarly identify Mercury as a good choice for tech-forward nonprofits, while noting that fundraising and nonprofit compliance tools have to come from external software.

Best if: donations arrive through Stripe/PayPal/other online processors and you want automated bookkeeping.

3. Crowded — most interesting if donation tracking is the priority

Crowded is worth a close look because it is built specifically for nonprofits, rather than adapting a small-business banking product to nonprofit needs. A 2026 comparison identifies its free Essentials tier and highlights automated donation tracking, donation receipts, expense tracking and compliance-oriented functionality.

I'd investigate this one first if you want the banking platform itself to understand that a donation isn't simply ordinary business revenue.

4. Bluevine — good if you have meaningful cash reserves

Bluevine's basic business checking has no monthly fee and unlimited transactions, and it stands out more for earning interest on idle operating cash than for nonprofit-specific functionality.

It's a good option if your nonprofit maintains a sizable reserve and wants the banking side to remain inexpensive while earning something on cash.

5. Novo — simple, low-cost option

Novo is worth considering for a very small nonprofit that mainly wants straightforward banking, invoicing and integrations without a monthly fee. Its differentiator is simplicity rather than nonprofit-specific accounting.

What I'd choose

For most small U.S. nonprofits: Relay + QuickBooks + a dedicated donation platform is probably the strongest combination.

Why? The bank handles cash organization and transaction controls, QuickBooks handles the general ledger and financial statements, and the fundraising platform handles donor records, receipts and campaign reporting. That separation usually produces much cleaner reporting than trying to force a business bank account to function as a donor database.

If you specifically want one platform to handle banking + donation tracking + nonprofit compliance, I'd investigate Crowded before the general-purpose fintechs.

One caveat: fintechs are not necessarily banks themselves; banking services and FDIC coverage are generally provided through partner banks. That's worth checking carefully when choosing a platform, especially if your nonprofit will hold substantial reserves.

If you tell me your nonprofit's approximate annual donations, number of users, whether donations come via Stripe/PayPal/checks, and whether you use QuickBooks, I can narrow this to the best 2–3 options and compare their actual fees and reporting workflows.

For a US-based non-profit, pure fintech "neobanks" (which partner with FDIC-insured institutions) are fantastic for low or zero monthly fees , but they generally do not natively track donor databases, issue tax-exempt receipts, or manage CRM pipelines . Instead, the best approach is pairing a zero-fee fintech banking platform with robust multi-account structures (to segregate restricted grants and general funds) and connecting it to dedicated accounting or donation software.

The top fintech and digital business banking platforms suited for non-profits looking for low fees and clean financial tracking include:

• Crowded (Visit Crowded)
  • Best For: Purpose-built financial management specifically for small non-profits, clubs, and community groups.
  • Fees: $0 monthly maintenance fees.
  • Tracking & Reporting Tools: Unlike standard fintechs, Crowded is explicitly engineered for non-profit workflows, handling chapter-based budgeting, expense approvals, and tracking funds by specific initiatives or member dues rather than forcing you to hack together standard business accounts.
• Relay (Visit Relay)
  • Best For: Granular cash-flow and fund separation (envelope-style budgeting).
  • Fees: $0 monthly fees, no minimum balances, and free ACH/domestic wires.
  • Tracking & Reporting Tools: You can open up to 20 individual checking accounts under a single login—each with its own distinct account and routing number. Non-profits use this to cleanly separate restricted grants, general operating funds, and specific fundraising campaigns. It features deep, bidirectional syncing with QuickBooks Online and Xero , passing itemized transaction feeds directly into your accounting software.
• Mercury (Visit Mercury)
  • Best For: Tech-forward or scaling non-profits with higher cash reserves.
  • Fees: $0 account fees, free domestic and international USD wires.
  • Tracking & Reporting Tools: Offers automated categorization rules, custom GL code application before syncing to accounting tools, and robust API access. While its multi-account setup is structured as sub-accounts under a primary ledger rather than 20 independent checking accounts (like Relay), its clean data export and automated receivables make reconciliation painless.
• Bluevine (Visit Bluevine)
  • Best For: Non-profits wanting to earn high interest on idle donation cash.
  • Fees: $0 monthly fees and no maintenance charges.
  • Tracking & Reporting Tools: Offers user-friendly sub-accounts and seamless integrations with major bookkeeping platforms, though it is more traditionally styled for straightforward interest-earning checking rather than complex fund accounting.

Note on Donation Tracking

For actual donation tracking, donor management, and automated 501(c)(3) tax receipts , you should integrate your chosen fintech bank feed with specialized low-cost or free software via TechSoup (such as Donorbox or Givebutter ) rather than relying on the bank interface itself.

If you'd like to narrow this down, let me know:

• What is your expected monthly donation volume and transaction count?
• Do you need multi-user permissions for board members or separate project managers?

I can help you pick the exact platform match and mapping strategy.

When looking for a US-based fintech or digital banking platform tailored to non-profits, it is important to note that pure fintechs rarely build deep, standalone donor CRM (Constituent Relationship Management) tools directly into their checking interfaces. Instead, specialized fintechs offer structural features (like sub-accounts for grant/fund tracking) or partner with software ecosystems that handle reporting and donation tracking.

The top options combining low-fee digital/fintech banking with strong tracking, budgeting, or integration capabilities for US non-profits include:

• Crowded : Purpose-built specifically for small non-profits, clubs, and community organizations. It features a $0 monthly fee , built-in tools for collecting dues or donations, and expense management designed around tracking specific programs or multi-chapter structures.
• Holdings : An emerging fintech platform explicitly focused on non-financial management for non-profits. It offers $0 monthly fees , competitive yield on balances, and unlimited sub-accounts —allowing you to partition funds, grants, or specific fundraising campaigns cleanly without needing expensive external fund accounting software.
• Relay : A powerful digital banking and spend-management fintech that offers a robust free tier with no monthly maintenance fees or minimum balance requirements. While it doesn't track donor names natively, it allows you to open multiple separate checking accounts/routing numbers (up to 20 on the free plan) to isolate different funding streams or project budgets, and it syncs seamlessly with accounting platforms like QuickBooks.
• Mercury : A popular fintech for modern organizations offering a completely free standard tier with no monthly fees and free domestic wires. While focused heavily on cash flow, invoicing, and treasury management, it integrates cleanly via API and third-party tools to automate your incoming donation data into your ledger.
• U.S. Bank (Nonprofit Checking) : Though technically a traditional regional/national bank rather than a pure startup fintech, U.S. Bank heavily matches fintech convenience with its Nonprofit Business Checking package. It features no monthly maintenance fee and stands out for offering built-in nonprofit payment processing tools directly tied to the account to help track incoming receivables and manage operational cash flow.

If you'd like to narrow this down, let me know:

• Does your non-profit need native fund/grant accounting built into the bank account, or do you already use a tool like QuickBooks or Xero?
• Do you expect to handle physical cash/check deposits , or is it 100% digital/online giving?

For a U.S.-based nonprofit, I’d focus on nonprofit-specific fintechs first, because ordinary business banking platforms tend to be inexpensive but leave donation tracking, restricted funds, donor acknowledgments, and reporting to separate software.

Best options

1. Crowded — best low-cost all-in-one

This is probably the most compelling option for a small nonprofit whose main requirement is donation collection + basic reporting. Its free Essentials plan includes a primary checking account, mobile check deposit, digital debit cards, transaction exports, custom donation pages, dues collection, and one free federal 990 filing per year.

There are no monthly subscription or minimum-balance fees. Donation processing is 2.99% for cards or $5 for ACH, and Crowded lets the donor choose to cover the processing cost.

My take: Excellent for a small 501(c)(3), membership organization, booster club, chapter, or volunteer-run nonprofit that wants banking and fundraising in one place.

2. Mazlo — best for serious nonprofit financial reporting

Mazlo is the strongest fit if you're dealing with restricted funds, grants, multiple programs, fiscal sponsorship, or detailed donor reporting.

It supports project-specific checking accounts, donation campaigns, automated donor acknowledgments/tax receipts, donor data from Stripe and PayPal, grant tracking, and transaction tagging by fund/project/accounting code. It can also export data and integrate with QuickBooks and Sage Intacct.

Its current pricing shows a free Core plan, while the Growth plan is $250/month and adds more accounts and unlimited donation campaigns. Inbound card donations are 2.9% + $0.20.

My take: If your board, funders, or auditors care about being able to answer “How much of this donation is restricted to Program X, and where did every dollar go?”, Mazlo is much more interesting than a generic fintech bank.

3. Relay — best inexpensive banking infrastructure

Relay explicitly supports U.S. nonprofits, including 501(c)(3) and 501(c)(6) organizations.

Its free Starter plan provides up to 20 checking accounts, two savings accounts, spend controls, receipt collection, invoicing and accounting integrations. That makes it particularly useful for separating operating funds, grants, programs, events, and restricted money without opening a traditional bank account for each.

The catch: Relay isn't really a donor-management system. Its invoice/payment tools can accept card payments and ACH, but you'd likely want a separate donor/CRM system for donor history and tax receipts.

My take: Great if you already use something like a donor CRM and primarily need a clean, low-cost banking layer.

4. Mercury — best general-purpose fintech

Mercury's free banking has no monthly fee, minimum balance, overdraft fee, domestic ACH fee, or domestic wire fee, and it provides free QuickBooks/Xero integrations, bill pay, expense controls, and transaction/accounting tools.

But Mercury isn't nonprofit-specific. Its strength is cheap, modern banking, not donation management. You'd generally combine it with Stripe, a donor CRM, or accounting software.

My take: A very good choice for a technology-oriented nonprofit that already has its fundraising stack figured out.

My ranking

If donation tracking and reporting are the priority:

1. Mazlo — best overall nonprofit financial management
2. Crowded — best value for a small nonprofit
3. Relay — best low-cost banking + fund separation
4. Mercury — best general fintech banking, but weakest nonprofit-specific functionality

One important distinction: banking transaction categorization isn't the same as nonprofit fund accounting. If you receive restricted grants/donations or need reliable donor-level reporting, I'd favor Mazlo or Crowded rather than choosing Mercury/Relay solely because their banking fees are $0.

If you tell me roughly annual donations/revenue (e.g. <$100k, $100k–$1M, $1M+) and whether you have restricted grants, I can narrow this to the best 2–3 choices and compare the actual annual cost, including donation-processing fees and accounting integrations.

For a US-based 501(c)(3) non-profit, choosing the right fintech business banking or hybrid financial platform depends on whether you need a dedicated operational bank account with built-in fund management or a specialized payment processor that syncs seamlessly with your accounting/CRM stack.

Fintech and neo-banking solutions that feature low fees and robust tracking/reporting tools for non-profits include:

• Holdings : Purpose-built specifically for small-to-midsize businesses and non-profits. It charges $0 in monthly account fees, requires no minimum balance, and provides unlimited free sub-accounts . These sub-accounts act as virtual buckets to cleanly segregate restricted funds, specific grants, or distinct programs without needing complex external software, complemented by built-in automated fund categorization and board-ready reporting.
• Crowded : Tailored specifically for community groups, clubs, and non-profits. It offers digital banking with low or no monthly account overhead, paired with built-in donation collection tools (supporting ACH, Apple Pay, Google Pay, and recurring gifts). Crowded stands out for its post-donation tracking, offering sub-accounts, transparent restricted fund visibility, automated tax-deductible receipt generation, and real-time ledger export features.
• Relay : A popular business banking fintech featuring transparent, fee-free basic checking and up to 20 individual virtual sub-accounts. While it doesn't have a native donation page builder, its granular multi-user permission controls, clear categorization, and deep, native integration with accounting platforms like QuickBooks Online and Xero make tracking incoming funds and running audit reports straightforward.
• Stripe (with Nonprofit Discount) : While technically a payment gateway and merchant processor rather than a standalone bank, verified 501(c)(3) organizations can apply for Stripe’s discounted nonprofit pricing rate (typically 2.2%+$0.3 0 per card transaction). Stripe features real-time analytics dashboards, tracking for recurring gift retention and failed payments, and embeddable donation elements that tie directly into whatever business bank account you link for payouts.
• PayPal Giving Fund / PayPal Business : An entry-level staple for smaller local charities. Verified non-profits enjoy discounted processing rates with no monthly platform fees. The integrated donation tracker logs reference numbers and donor data, making basic reconciliation simple, though it lacks the advanced multi-fund accounting depth of dedicated financial stacks.

To help narrow down the best fit, could you share:

• Are you looking for a primary bank account replacement or just a donation payment gateway?
• Approximately how many transactions or donors do you process monthly?

For a U.S. nonprofit, I’d narrow the fintech field to Crowded, Relay, Mercury, and Bluevine. The important distinction is that most fintech business accounts are cheap banking platforms, but only some meaningfully help with donation/fund tracking.

1. Crowded — best if donation tracking is a priority

This is the most interesting option if you want banking and nonprofit-specific financial administration in one place. Its free Essentials tier includes a checking account, transaction exports, custom donation pages, dues collection management, and IRS 990 filing (one per year). Pro adds recurring donations, additional accounts, receipt uploads, and additional nonprofit reporting/compliance functionality.

The catch is payment processing: card donations are 2.99% + $0.60 minimum, ACH collection is $5 per transaction, and in-person payments are 3.99% + $0.50. Donors can elect to cover processing costs.

My take: If you're a small or midsize 501(c)(3) that wants to see who donated, what was collected, and how the money is moving without assembling five different systems, start here.

2. Relay — best for restricted funds and budgeting

Relay is particularly good if your nonprofit needs to keep money physically/separately organized—for example, General Operations, Restricted Grant A, Programs, Events, and Reserves. Its free Starter plan currently allows up to 20 checking accounts, includes receipt uploads/reminders, spend controls, accounting integrations, and unlimited users.

It doesn't have Crowded's donor-management functionality, though. You'd generally pair it with your donation platform/CRM and QuickBooks or Xero.

My take: Probably the best choice if your biggest accounting headache is keeping grants, programs, and restricted funds separated rather than managing donor relationships.

3. Mercury — best banking infrastructure

Mercury offers free checking/savings, no monthly or overdraft fees, free ACH, free domestic and USD international wires, customizable permissions, automated transfers, bill pay, and QuickBooks/Xero integrations.

But it is not nonprofit-specific. A current comparison of nonprofit accounts specifically notes that Mercury lacks built-in donation tracking and nonprofit-specific tools, so you'd want something like a donor CRM/fundraising platform alongside it.

My take: Excellent if your nonprofit already has a fundraising system and primarily needs a clean, inexpensive financial operating account.

4. Bluevine — best if earning interest matters

Bluevine's Standard account has no monthly fee, no minimum balance, unlimited transactions, and free standard ACH. It also offers sub-accounts, bill pay, AP automation, and team debit cards. Nonprofit organizations are explicitly eligible for Business Checking.

The Standard plan can currently earn 1.3% APY up to $250,000 when you meet the activity requirement; higher-tier plans offer more.

But, like Mercury, it isn't really a donor-management platform.

My take: Attractive for a nonprofit holding meaningful cash reserves, particularly if you want low-cost banking + interest, but I'd still use separate fundraising/accounting software.

What I'd choose

For a small nonprofit: Crowded is the most compelling all-in-one option.

For a nonprofit with grants/restricted funds: Relay + QuickBooks/Xero + your existing donation platform is probably the strongest setup.

For a more established nonprofit with sophisticated existing systems: Mercury + donor CRM + accounting software gives you a very flexible technology stack.

For a cash-rich nonprofit: Consider Bluevine for operating/reserve cash because of its interest-bearing checking, while keeping donor reporting elsewhere.

One important caveat: don't evaluate the banking fee alone. For nonprofits, the cost of accepting a $10,000 credit-card donation stream can dwarf the $0–$30 monthly banking fee. Donation processing rates, ACH costs, donor receipts, restricted-fund accounting, QuickBooks synchronization, and year-end reporting are much more consequential.

Also, Crowded, Relay, Mercury, and Bluevine are fintechs rather than traditional banks; the banking/deposit relationship is provided through FDIC-insured partner banks.

If you tell me your nonprofit's approximate annual donations, number of donors, whether you use QuickBooks, and whether you have restricted grants, I can narrow this to the best 2–3 setups and estimate the annual fees.
