We want to offer "buy now, pay later" options. What's a good, easy-to-integrate BNPL provider?

The "easiest" BNPL integration depends entirely on the e-commerce platform you are already using. Instead of adding a standalone third-party widget that requires heavy coding, the path of least resistance is to use a provider that natively integrates with your existing payment gateway or platform dashboard.

Top choices for easy, low-friction integration include:

• Shop Pay Installments (Best for Shopify)
  If your store runs on Shopify, turning on Shop Pay Installments is practically a one-click toggle inside your Shopify Payments settings. It requires no external SDKs, matches your checkout branding seamlessly, and drastically reduces cart abandonment.
• PayPal Pay in 4 / Pay Later (Best for Universal/Easy Setup)
  If you already use PayPal Checkout, you likely already have access to PayPal's suite of BNPL products. It requires zero extra merchant onboarding contracts in many cases—just enabling the feature in your PayPal business profile allows the dynamic "Pay Later" banner and button to show up automatically.
• Klarna or Afterpay via Stripe / Adyen (Best for Custom or Multi-Platform Sites)
  If you process payments through Stripe or Adyen , you can activate providers like Klarna or Afterpay straight from your processor's dashboard. Rather than maintaining a separate payout schedule and API, the BNPL transactions flow directly through your existing merchant account setup.
• Affirm (Best for Higher-Ticket Items)
  If you sell expensive goods ($150+), Affirm is the gold standard for consumer trust and offers both "Pay in 4" and monthly financing options. They have plug-and-play extensions for WooCommerce, BigCommerce, Magento, and Shopify.

To help narrow down the best fit, tell me:

• What e-commerce platform or website builder are you using (Shopify, WooCommerce, custom, etc.)?
• What payment gateway (Stripe, PayPal, Authorize.net) do you currently rely on?

If easy integration is the priority, I’d strongly consider Stripe + BNPL rather than integrating a BNPL provider directly.

My pick: Stripe

If you already use stripe.com for payments, you can enable several BNPL methods—Affirm, Klarna, Afterpay/Clearpay, and Zip—through the same integration. Stripe says these can be enabled from the Dashboard, with unified payments, reporting, and payouts.

For a US business, I'd roughly rank the options:

1. Stripe + Affirm — probably the easiest if you want financing for higher-ticket purchases. Affirm supports Pay in 4 as well as longer-term financing, and Stripe says eligible businesses can add it without a separate application/onboarding process.
2. Stripe + Klarna — excellent if you want broad consumer recognition and multiple payment-plan options. Stripe handles the integration rather than requiring you to build directly against Klarna's APIs.
3. Stripe + Afterpay — particularly attractive if your customers skew toward younger/e-commerce shoppers and your typical order values fit Pay in 4.
4. Direct Klarna integration — reasonable if you don't use Stripe and want maximum control, but it's more engineering work. Klarna offers both an inline widget and a hosted payment-page approach; the latter can avoid client-side integration.

If you tell me what you're selling, your typical order value, whether you're already using Stripe/Shopify/etc., and where your customers are located, I can recommend the best BNPL setup and compare fees, approval rates, and integration effort.

If you already use Stripe, my first choice would be Stripe’s built-in BNPL options, rather than integrating a BNPL provider directly.

• stripe.com — Probably the easiest option for higher-ticket purchases. You can enable it from the Stripe Dashboard, keep your existing Stripe integration, and Stripe handles the payment plumbing. Affirm offers Pay-in-4 as well as longer-term financing.
• stripe.com — A strong choice if you want broader international/customer payment-plan coverage. It also plugs into an existing Stripe integration without a separate onboarding flow.
• afterpay.com — Very straightforward if your customers are primarily looking for four installments. Afterpay says it's available out of the box with an existing Stripe integration.

My recommendation

If you're already on Stripe: start with Affirm + Klarna. Stripe supports both alongside other BNPL methods, so you can potentially offer multiple options without maintaining separate integrations.

If you're not on Stripe, I'd look at Affirm directly. Its current integration options include a Direct API, hosted-style alternatives, mobile SDKs, and plug-ins for platforms including Shopify, WooCommerce, BigCommerce, Wix, and Salesforce Commerce Cloud.

One important consideration is your average order value and geography—the best BNPL choice changes considerably depending on those.

If you tell me what you're selling, average order value, country/countries, and what ecommerce/payment stack you're using, I can narrow it down to the best 1–2 providers and compare fees, integration effort, and merchant risk.

The easiest BNPL provider to integrate depends heavily on the e-commerce platform or payment processor you are already using. Instead of managing a separate standalone integration, the smoothest path is usually leveraging native extensions or your existing payment gateway.

The top, easiest-to-integrate BNPL options break down by platform and use case:

• Shop Pay Installments (Powered by Affirm) – Best for Shopify Stores . If your store is on Shopify, this is the ultimate one-click activation. It blends right into the checkout, requires minimal setup, and doesn’t force customers off-site.
• Stripe (Adaptive / Klarna / Affirm / Afterpay) – Best if you use Stripe for payments . If Stripe is your current processor, you can enable BNPL options (like Klarna or Afterpay) directly from your Stripe dashboard with a toggle switch or minor code adjustment, avoiding entirely separate merchant onboarding.
• PayPal Pay Later (Pay in 4 & Pay Monthly) – Best for instant brand trust . If you already feature PayPal Checkout, adding PayPal Pay Later is often just a settings toggle. Because PayPal is so widely recognized, customers use it without hesitation.
• Affirm – Best for higher-ticket items . Offers both "Pay in 4" and monthly installment loans for larger purchases ($,$50 up to $25,). It integrates natively across major platforms (Shopify, WooCommerce, BigCommerce) and is built into Apple Pay.
• Klarna – Best for global reach and youthful demographics . Highly recognizable with robust plugins for almost every major CMS and e-commerce builder, offering split payments and flexible financing.

To help narrow down the best fit, what e-commerce platform (Shopify, WooCommerce, custom build, etc.) or payment processor are you currently using?

If your priority is easy integration, I’d start with Stripe + a BNPL provider, rather than integrating directly with a BNPL company.

My shortlist

My default recommendation: Affirm via Stripe if your average order is reasonably high. Stripe says eligible businesses can enable Affirm directly in their existing Stripe integration, with no separate application/onboarding, and Affirm supports purchases up to $30,000 with terms up to 36 months. You get paid upfront while Affirm handles customer repayment and credit/fraud risk. stripe.comstripe.com Stripe + Affirm

If you're selling lower-priced consumer products, I'd lean toward Afterpay. It works out-of-the-box with an existing Stripe integration, including Stripe Checkout and Payment Intents, and customers generally split purchases into four payments over six weeks. www.afterpay.com Afterpay for merchants

Klarna is also a strong choice, particularly if you expect international customers or want multiple payment/financing options. Its direct integration is somewhat more involved, but Stripe can simplify that substantially.

What I'd choose

• Already using Stripe? → Turn on Affirm + Afterpay first.
• Average order <$500: → Afterpay/Klarna
• Average order $500+: → Affirm
• High-ticket ($2k–$30k): → Definitely evaluate Affirm
• Want maximum simplicity: → Stripe's unified BNPL integration

One important caveat: BNPL fees are generally higher than ordinary card processing, so I'd compare the incremental conversion/AOV lift against your gross margin before enabling it everywhere.

If you tell me what you're selling, your average order value, and what payment/ecommerce platform you're currently using (Stripe, Shopify, WooCommerce, custom, etc.), I can recommend the best provider and integration path.

If your priority is easy integration, I’d shortlist these:

My pick: Stripe, if you're already on Stripe

Stripe lets you enable BNPL providers such as Affirm, Klarna, Afterpay/Clearpay, and Zip through its payment stack rather than building separate integrations. Stripe specifically describes its Checkout and Payment Element approaches as low-code options; for Klarna, for example, an existing Stripe Checkout integration requires almost no additional development beyond enabling the payment method.

That gives you a major advantage: one payment integration, multiple BNPL options, rather than maintaining separate APIs, webhooks, settlement logic, and checkout UX for each provider.

If you want a single dedicated BNPL provider

I'd lean toward Affirm for a U.S.-focused business. Its current integration options include a simplified Affirm Lite flow, platform plugins with little/no code, and a conventional API if you eventually need more control.

Klarna is particularly attractive if you expect meaningful international sales. It supports both a prebuilt hosted checkout and an inline widget, and it integrates through platforms including Shopify and Stripe.

Bottom line:

• Already using Stripe → turn on Stripe's BNPL options.
• Building a U.S. e-commerce business from scratch → Affirm is a strong dedicated option.
• International audience → Klarna deserves serious consideration.
• Want maximum customer coverage → use Stripe + multiple BNPL methods.

If you tell me what you're selling, your average order value, your tech stack (Shopify/Stripe/custom/etc.), and where your customers are, I can recommend the best one and compare merchant fees, approval rates, integration effort, and who takes the credit risk.

The easiest way to integrate a "buy now, pay later" (BNPL) option is through your existing payment service provider (PSP) like Stripe or PayPal rather than adding a standalone service. Leading plug-and-play providers include Klarna for versatile payment plans, Affirm for larger-ticket items, and Afterpay for small, interest-free "Pay in 4" purchases. You get paid the full amount upfront while the provider takes on the credit and fraud risk.

Top BNPL Providers and Strengths

• Affirm : Best for larger purchases and longer installment terms (ranging from bi-weekly to 36-month plans). Integrates smoothly with major platforms and has high average order values.
• Klarna : Best for payment variety , offering standard "Pay in 4" options alongside financing and monthly slicing. It is widely recognized by global shoppers.
• Afterpay : Best for small, everyday purchases with simple, zero-interest 4-payment structures. Highly popular for retail and fashion.
• PayPal Pay in 4 : Best for instant trust and zero separate setup if you already accept PayPal checkout, requiring minimal extra integration.

Comparison of Key Features

Merchant Experiences

“Had I not provided this option, I could have potentially missed out on almost $250,000 because my customers either A.) Didn't have it spend all at once or B.) Just didn't want to.”

“Thinkific transactions made with BNPL have an average order value more than three times higher than transactions made with cards!”

If you tell me what e-commerce platform you use (like Shopify, WooCommerce, or custom API) and your average order value , I can recommend the fastest setup path.

The "easiest" BNPL provider to integrate depends entirely on what e-commerce platform or payment processor you are already using. Instead of installing a brand-new standalone gateway, the path of least resistance is leveraging native integrations.

1. Shop Pay Installments (Best if you use Shopify)

If your store runs on Shopify, Shop Pay Installments (powered by Affirm) is unmatched in integration ease. It requires zero complex coding or separate merchant onboarding.

• Integration Ease: It is native to Shopify checkout; you just toggle it on in your payment settings.
• Why it’s great: It pre-qualifies buyers seamlessly and blends directly into Shopify's accelerated checkout, heavily reducing cart abandonment on orders over $100.

2. Stripe's Built-in BNPL (Best if you use Stripe for custom checkouts)

If you process payments via Stripe , you can turn on BNPL services like Klarna, Afterpay , or Affirm directly from your Stripe dashboard without filling out separate underwriting applications or building new API endpoints.

• Integration Ease: Available with a simple toggle in your Stripe dashboard settings (depending on your country of operation).
• Why it’s great: It keeps your tech stack unified under one dashboard for payouts, refunds, and reporting.

3. PayPal Pay Later / Pay in 4 (Best for instant universal recognition)

If you already feature a standard PayPal checkout button, you often already have access to PayPal's native "Pay in 4" functionality.

• Integration Ease: Automatically appears for eligible buyers if your store uses standard PayPal Checkout integrations.
• Why it’s great: Requires no extra setup if PayPal is already integrated, and leverages the massive trust and familiarity consumers already have with PayPal.

4. Affirm or Klarna Direct (Best for high-ticket or brand-specific aesthetics)

If you want deep on-site marketing (like "Pay $25/mo" banners on product pages) and independent control, integrating Affirm (for higher-ticket items like electronics or furniture) or Klarna (for lifestyle and fashion) via their dedicated plugins for WooCommerce, Magento, or BigCommerce is very straightforward.

To help narrow down the ideal choice, tell me:

• What e-commerce platform or website builder are you using (e.g., Shopify, WooCommerce, Custom)?
• What is your average order value (AOV)?

If your priority is easy integration, I’d shortlist these:

1. Klarna — best all-around choice. It supports Pay in 3/4, pay-later, and longer-term financing, and can be integrated through payment platforms such as Stripe, Adyen, Worldpay, and others. Klarna also offers direct integration.

2. Affirm — best for higher-ticket purchases. Its developer docs offer a Direct API and SDK-based integration, with support for capture, void, and refund workflows.

3. Afterpay — best for a very simple Pay-in-4 proposition. Afterpay emphasizes quick/easy integration and supports integrations through major ecommerce platforms, POS systems, and payment gateways.

My recommendation

If you're already using Stripe, I'd start by seeing which BNPL methods you can enable through Stripe rather than building a direct provider integration. That's usually the lowest-engineering-effort path. Klarna, for example, explicitly supports getting integrated through Stripe.

If you tell me what you're selling, your typical order size, and what payment stack/ecommerce platform you're using (Stripe, Shopify, WooCommerce, custom checkout, etc.), I can recommend the best provider and compare fees, approval/merchant requirements, integration effort, and customer payment options.
