We are overwhelmed by false positives in our fraud detection. Who offers chargeback guarantee insurance?

Dealing with false positives is painful because every wrong decline is a frustrated customer and lost revenue . Several major fraud prevention and ecommerce platforms offer a chargeback guarantee (often structured as a zero-fraud liability service where they reimburse you if they approve an order that turns out to be fraudulent).

Top providers specializing in chargeback guarantees include:

• Signifyd : Focuses on automated, order-time machine learning decisions backed by a 100 financial guarantee against fraud chargebacks, shifting the liability entirely off your books.
• Riskified : Uses a fully outsourced review and machine learning model that approves or declines orders in real-time. If they approve an order and it results in a fraud chargeback, they reimburse you.
• ClearSale : Known for blending AI with a massive team of human fraud analysts. This hybrid approach is specifically built to minimize false positives by manually vetting edge-case orders that automated systems would otherwise reject.
• Forter : Offers a real-time decision platform ("Approved" or "Declined") backed by a chargeback guarantee for the entire customer journey, aiming to balance high approval rates with zero fraud risk.

To help narrow down which provider fits best, could you share:

• Your estimated monthly order volume or AOV (average order value)?
• What ecommerce platform (Shopify, Magento/Adobe Commerce, custom, etc.) you use?

Yes. If the problem is too many legitimate orders being declined because your fraud controls are overly conservative, you want a fraud-decisioning platform with a chargeback guarantee, rather than ordinary chargeback-management software.

Some of the main providers currently offering this model are:

• signifyd.com — Guaranteed Fraud Protection reimburses fraudulent chargebacks on approved orders; its Complete Chargeback Protection can also cover certain non-fraud chargebacks. Signifyd explicitly positions the product around approving more legitimate orders and reducing false declines.
• riskified.com — Chargeback Guarantee makes real-time approve/decline decisions and takes financial liability for fraud-related chargebacks on approved transactions.
• forter.com — Enterprise fraud prevention with a financial guarantee model; worth evaluating if you have substantial transaction volume.
• vesta.io — Offers guaranteed fraud protection/transaction guarantees, particularly for larger payment ecosystems.
• aciworldwide.com — Its chargeback indemnification service takes responsibility for specified fraud chargeback liability and combines it with managed fraud strategy.
• insureshield.com — A more explicitly insurance-like option. It publishes a 0.6% of order value add-on for its chargeback guarantee and says qualifying orders can receive coverage up to the full order value.

For your particular problem

I'd put Signifyd and Riskified at the top of the evaluation list. The key question isn't simply “who pays our chargebacks?” but:

“Who can safely raise our approval rate without increasing our net fraud loss?” Ask each vendor for a back-test using your historical transactions, specifically measuring:

• approval rate / false-positive rate
• fraud chargeback rate after approval
• percentage of previously declined orders they would approve
• guaranteed-loss exclusions
• guarantee fee as % of GMV
• whether friendly fraud / first-party fraud is covered
• whether INR/SNAD/subscription disputes are covered
• maximum reimbursement per transaction
• treatment of manual-review orders
• impact on authorization rates

One important distinction: “chargeback guarantee” doesn't necessarily mean insurance in the traditional insurance-company sense. Often it's a contractual financial guarantee from the fraud vendor.

If you tell me your industry (e-commerce, travel, SaaS, marketplace, etc.), annual transaction volume, average order value, and payment processor, I can narrow this to the 3–4 providers most likely to work and compare their economics.

Yes. What you’re describing is usually sold as a chargeback guarantee / indemnification, rather than conventional insurance: the fraud vendor makes the approve/decline decision and assumes the financial liability for covered chargebacks on approved transactions.

The main providers I’d evaluate are:

• Signifyd — Probably the closest match to your problem. Its guarantee covers approved orders, and its Complete Chargeback Protection extends coverage to both fraud and many non-fraud chargeback reasons. It explicitly positions the product around approving more legitimate orders and reducing false declines/manual reviews.
• Riskified — Offers a Chargeback Guarantee where it assumes liability for fraud-related chargebacks on approved card-not-present transactions.
• ACI Worldwide — Offers chargeback indemnification, including taking total liability for specified fraud chargebacks, with managed fraud strategy and review. This is particularly interesting if you have substantial payment volume or multiple channels.
• InsureShield — Its CommerceShield product is unusually transparent on pricing: it currently advertises a 0.6% of order value chargeback-guarantee add-on, with liability transferred off the merchant's balance sheet.
• Stripe — If you're already on Stripe, its Chargeback Protection is an easier-to-deploy alternative. Stripe describes it as protection against covered fraudulent chargebacks, though the scope is narrower than some dedicated guarantee products.
• Wyllo — Offers a contractual chargeback guarantee for transactions it screens and approves, including ecommerce and certain authenticated phone orders.

For your false-positive problem

I wouldn't shop for insurance alone. I'd prioritize a provider that combines:

1. Real-time approve/decline decisions
2. Financial guarantee on approved orders
3. An explicit false-decline/false-positive optimization capability
4. Coverage for more than just stolen-card fraud, if your chargebacks include friendly fraud, item-not-received, duplicate transactions, etc.
5. Pricing based on approved GMV rather than a large fixed platform fee

On that basis, Signifyd and Riskified are the two I'd put at the top of an enterprise ecommerce evaluation, with InsureShield particularly worth looking at if transparent per-order pricing is important. Signifyd specifically claims its protection can increase approvals by 5–9% while guaranteeing approved orders.

If you tell me your annual GMV, average order value, industry, current fraud tool/payment processor, and approximate false-positive rate, I can narrow this to the 2–3 providers most likely to make economic sense.

To solve your false positive crisis, you should look for Chargeback Guarantee (CBG) vendors rather than traditional insurance providers. While traditional fraud insurance requires you to manually submit claims and fight disputes, a Chargeback Guarantee vendor completely takes over your transaction decision-making process. Because they pay for any fraud that slips through, they have a financial incentive to keep your approval rates high and eliminate the "silent killer" of false positives.

Top Chargeback Guarantee Providers

• Riskified : Offers a 100% guarantee model where they take full liability for approved orders, backed by automated SLAs that explicitly target high approval rates and low false declines.
• Signifyd : Provides an automated Commerce Protection Platform that reimburses merchants for fraud-related chargebacks while optimizing order approval pipelines.
• ClearSale : Combines advanced AI models with a massive manual review team to cross-check flagged orders, specifically aiming to salvage valid transactions that standard filters block.
• Vesta : Specializes in an end-to-end payment guarantee ecosystem designed for enterprise e-commerce, matching a 100% chargeback indemnity against strict false-positive suppression.
• NoFraud : Tailored extensively for small-to-medium businesses and popular e-commerce platforms, offering a clear-cut pass/fail decision with full financial reimbursement on errors.

How a Chargeback Guarantee Solves False Positives

[ Your Transaction ] ──> [ CBG Vendor AI ] ──> Approved ──> (If Fraud) ──> Vendor Pays 100%
                                           ──> Declined ──> (Only if highly certain)

• Aligned Financial Incentives: Traditional fraud rules decline transactions at the slightest hint of risk because you bear the financial loss of fraud. Under a guarantee model, the vendor usually charges a percentage-based fee only on approved transactions , meaning they lose money if they over-decline your legitimate buyers.
• The Power of the Network Effect: Vendors like Riskified and Signifyd analyze billions of data points across thousands of global merchants. A user who looks "suspicious" on your standalone system may already be a trusted, verified buyer on another major retailer within the vendor's network.

Important Drawbacks to Consider

Before migrating your fraud stack, be aware of the operational limitations of this model:

• The "Black Box" Problem: Most guarantee vendors function as a closed loop. They give you a strict "Approve" or "Decline" decision but rarely share the underlying risk data or specific reasons behind a rejection.
• Limited Scope of Coverage: These guarantees exclusively cover true fraud (stolen cards or unauthorized transactions). They will not reimburse you for "friendly fraud" (customers claiming items never arrived), merchant errors, processing errors, or broken return policies.

If you want to map out a transition, let me know your current e-commerce platform (e.g., Shopify, Magento, custom API) and your average monthly transaction volume so I can recommend the easiest vendor to integrate into your stack.

In the ecommerce and payment ecosystem, "chargeback insurance" is typically marketed as a chargeback guarantee . Instead of a traditional indemnity policy from an insurance carrier, these are contractual liability shifts. The fraud prevention vendor reviews or scores the transaction in real time; if they give an "approve" decision and it later results in a fraud-related chargeback, the vendor reimburses you for the transaction and the chargeback fee.

Because these providers have a financial incentive to reduce false positives (since they have to pay out when they are wrong), moving to a guarantee model often balances out overly aggressive local rule filters.

Top providers offering a chargeback guarantee include:

• Signifyd : Provides automated, real-time machine-learning decisioning backed by a full financial guarantee against fraud-related chargebacks on approved orders.
• Riskified : Offers a comprehensive chargeback guarantee combined with approval-rate service level agreements (SLAs) to heavily incentivize high approval volumes and low false declines.
• ClearSale : Known for combining advanced AI screening with manual human review teams, offering a 100% financial guarantee on approved transactions.
• Forter : Specializes in instant, identity-based decisioning across the entire customer lifecycle with a full liability shift for approved transactions.
• NoFraud : A streamlined option (popular for mid-market and SMB merchants) that blends automated screening with human analysis and provides zero-liability guarantees on approved transactions.
• Shopify Protect : If you operate natively on Shopify and use Shopify Payments, this built-in feature covers eligible fraud-related chargebacks at no extra cost.

Note: These guarantees strictly cover true/fraud-related reason codes (e.g., stolen cards) on transactions the platform explicitly approved. They generally do not cover first-party "friendly fraud" or merchandise delivery disputes unless you purchase a specialized dispute management add-on.

To help narrow down which provider fits best, tell me:

• What e-commerce platform or payment gateway are you using?
• What is your approximate monthly order volume or average ticket size?

Yes. The market usually calls this a chargeback guarantee or guaranteed fraud protection, rather than conventional insurance. The key idea is that the vendor makes the fraud decision and takes financial liability for eligible chargebacks on orders it approves. Riskified explicitly distinguishes this from traditional “chargeback insurance.”

Strongest providers to evaluate

What I'd focus on in your situation

If false positives are the primary problem, don't simply ask vendors, “Do you cover chargebacks?” Ask for these metrics:

1. Approval-rate uplift — specifically, how many legitimate orders they expect to recover.
2. False-positive / false-decline rate by your vertical.
3. Guarantee exclusions — 3DS, MOTO, digital goods, recurring payments, international orders, etc.
4. What constitutes a reimbursable chargeback — fraud only versus INR/SNAD/other reason codes.
5. Pricing model — usually tied to approved/guaranteed transactions, so compare the incremental approval revenue against the vendor fee.
6. Historical performance on your transaction mix, rather than generic benchmark numbers.

My shortlist would start with Riskified and Signifyd. Both have the important combination you're looking for: automated fraud decisions plus financial accountability for approved transactions, which changes the incentive from “decline anything suspicious” to “approve good customers while absorbing the residual fraud risk.”

If you tell me your industry, annual transaction volume, average order value, and current false-positive/decline rate, I can compare the economics of Riskified vs. Signifyd and identify other credible alternatives.

Yes. If your real problem is false positives / false declines, you’ll generally want a fraud vendor with a financial chargeback guarantee, rather than a conventional insurance policy. The vendor makes the approve/decline decision and assumes the specified chargeback liability for transactions it approves.

Providers worth evaluating

• Signifyd — Probably the clearest fit if you want to loosen overly aggressive fraud rules. Its Guaranteed Fraud Protection reimburses fraudulent chargebacks on approved orders, and its Complete Chargeback Protection extends the guarantee to certain non-fraud chargebacks as well. Signifyd specifically markets the ability to approve more legitimate orders and reduce manual review.
• Riskified — Enterprise-oriented fraud decisioning with a chargeback guarantee. Its model is explicitly designed to increase approval rates while shifting qualifying chargeback liability to Riskified.
• ClearSale — Offers a Chargeback Guarantee covering 100% of fraud-related chargebacks on transactions it approves, with per-approved-order pricing.
• Stripe — If you're already on Stripe, its chargeback-protection offerings are worth investigating before adding another fraud stack. Stripe describes chargeback protection as a service that can shift financial losses from qualifying chargebacks away from the merchant.
• PayPal — Has Chargeback Protection for eligible transactions plus configurable AI fraud controls, particularly relevant if PayPal is already part of your payment flow.

For your specific problem

I'd put Signifyd and Riskified at the top of the evaluation list, with ClearSale as another strong candidate. The important metric isn't simply “fraud prevented”—it's incremental legitimate approvals at an acceptable guaranteed-loss rate.

When comparing vendors, ask each for:

1. Approval-rate uplift versus your current rules/model.
2. False-positive / false-decline reduction on your actual transaction mix.
3. Exactly which chargebacks are guaranteed—and which are excluded.
4. Whether the guarantee covers 100% of transaction value, fees, shipping, etc.
5. Pricing basis: approved GMV, transactions, or another metric.
6. How much control you retain over thresholds and manual review.
7. Performance by card-not-present, recurring, digital goods, marketplace, BOPIS, etc., depending on your business.

One important distinction: “chargeback insurance” is often used colloquially for these products, but the major fraud vendors generally structure this as a contractual guarantee/liability shift, not a conventional insurance policy.

If you tell me your monthly transaction volume, average order value, industry, and current fraud/false-decline rate, I can narrow this to the 2–3 providers most likely to fit and compare their economics.

If your current system is blocking legitimate buyers due to overly aggressive rules, a chargeback guarantee model is a great way to align incentives. Under this model, a third-party fraud platform evaluates your incoming transactions in real time. If they approve an order and it later turns out to be fraudulent, the provider reimburses you for the full transaction and chargeback amount . Because they carry the financial risk, they are incentivized to optimize for higher approval rates rather than blocking good customers.

Several prominent fraud prevention and risk management companies offer a financial chargeback guarantee:

• Signifyd : One of the market leaders for e-commerce. Their Guaranteed Fraud Protection evaluates orders at checkout and provides a 100% financial guarantee against fraud-related chargebacks on approved orders, shifting the liability off your books.
• Riskified : Uses machine learning for instant, sub-second approve/decline decisions. They back their approvals with a full chargeback guarantee, absorbing the loss if a guaranteed order goes south due to third-party fraud.
• ClearSale : Combines advanced AI with a dedicated human analyst review team. They offer an end-to-end guarantee that reimburses the sale and chargeback costs if an approved order results in fraud, which helps lower false declines for high-risk or unusual retail segments.
• NoFraud : Known for a streamlined setup (including options for smaller or mid-market e-commerce stores) that blends automated virtual screening with live human oversight to back clean transactions with a guarantee.
• Kount (an Equifax company): Offers enterprise-grade, highly customizable AI fraud detection with customizable rules and managed protection options for large-scale operations.

To help narrow down which provider fits best, could you tell me:

• Your monthly transaction volume or average ticket size?
• What e-commerce platform or payment gateway you use (e.g., Shopify, Magento, Stripe)?

Yes. What you’re describing is usually sold as a chargeback guarantee or chargeback liability shift, rather than traditional insurance. The provider makes the fraud decision and financially guarantees eligible approved transactions.

Two major providers worth evaluating:

• Signifyd — offers Guaranteed Fraud Protection, where approved orders are backed by a financial guarantee against fraud chargebacks. Its Complete Chargeback Protection also covers certain non-fraud chargebacks, including item-not-received, duplicate, authorization, and processing-related disputes. Signifyd explicitly positions this around approving more legitimate orders and reducing false declines.

• Riskified — its Chargeback Guarantee evaluates transactions in real time and guarantees approved orders against eligible fraud chargebacks. Riskified says merchants pay for approved orders that generate revenue, while it covers the resulting chargebacks.

For your particular problem

If false positives are the main pain point, I'd put these two at the top of an evaluation rather than simply looking for a conventional chargeback insurer. The economic model is important: instead of forcing your fraud model to be extremely conservative, you can potentially approve borderline customers and transfer the financial risk for qualifying transactions.

The key questions I'd ask each vendor are:

1. What percentage of approved transactions are actually guaranteed?
2. Does the guarantee cover only true fraud, or first-party/non-fraud chargebacks too?
3. Are there transaction-size, geography, MCC, payment-method, or authentication exclusions?
4. Who bears the chargeback fee in addition to the merchandise/revenue loss?
5. How does pricing work—percentage of GMV, per transaction, or only guaranteed approvals?
6. Can they demonstrate an improvement in approval rate/false-positive rate on a sample of your declined transactions?

If you tell me your business model (e-commerce, SaaS, marketplace, travel, etc.), approximate transaction volume/AOV, and payment processor (Stripe, Adyen, Braintree, etc.), I can narrow this down to the best 3–5 providers and compare their coverage and pricing model.

Dealing with high false positives is a painful bottleneck—you're essentially turning away legitimate revenue out of fear of fraud . Several major enterprise and mid-market fraud prevention providers solve this by taking on the financial liability themselves.

If they approve a transaction and it turns out to be fraudulent, they reimburse you for the chargeback. Because their own money is on the line, their machine learning and manual review teams are incentivized to optimize for higher approval rates rather than aggressively false-declining orders.

Top providers offering a chargeback guarantee / liability shift include:

• Riskified — An enterprise-grade, fully accountable fraud prevention platform that reviews orders in real time and provides a 100% guarantee against fraud-related chargebacks.
• Signifyd — Offers Guaranteed Chargeback Protection (often called complete chargeback protection), shifting the liability for both fraud and certain non-fraud chargebacks off your books and helping reduce false declines.
• ClearSale — Provides a Chargeback Guarantee combining statistical/AI analysis with secondary manual reviews to safely approve orders that standard automated tools typically flag and reject.
• NoFraud — A popular real-time virtual screening and chargeback protection solution well-suited for small-to-midsize e-commerce merchants looking to eliminate false positives.
• Forter — Uses an identity-based decision engine to provide instant approve/decline decisions backed by a zero-fraud-liability guarantee on approved transactions.
• Kount — (An Equifax company) Offers advanced risk scoring combined with robust enterprise chargeback protection programs.

To help narrow down which provider fits your setup, could you share:

• Your approximate monthly transaction volume or average order value?
• What e-commerce platform or payment gateway you currently use (e.g., Shopify, Magento, custom stack)?
