Overview

FraudLabs Pro is an online payment-fraud screening service for merchants who need a transaction risk score and a suggested approve, review, or reject decision. Its mix of storefront modules, a REST API, and a free entry plan makes it a practical starting point for online sellers, though growing order volume quickly makes query limits and monthly pricing central to the choice.

It is strongest for merchants who want configurable checks across order and customer data; it is not a chargeback guarantee. Compare it with other options in our Payment Fraud Detection Software and Fraud Detection Software lists.

Key features

Risk scoring and actions: FraudLabs Pro assigns a fraud score and recommends approval, review, or rejection. That gives merchants a consistent signal for order handling, rather than a promise that a disputed payment will be covered.
Broad validation checks: Signals include IP location and proxy use, billing and shipping addresses, user accounts, email, disposable phone numbers, credit cards, transaction details, devices, and blacklists. Custom rules, real-time scoring, and device fingerprinting support a more tailored screening setup, although the number of validation rules varies sharply by plan.
Learning from merchant decisions: Its machine-learning models analyze transaction history and merchants’ approvals, rejections, and blacklist actions to learn fraud patterns. This makes the service more relevant to stores that can feed it an ongoing stream of decisions.
Storefront and API access: Ready-made modules cover Shopify, WooCommerce, Magento, PrestaShop, BigCommerce, OpenCart, WHMCS, and other platforms; a REST API is also available. That breadth suits merchants who want to connect screening to an existing store rather than build every integration themselves.
Mobile access: The Micro plan includes Android and iOS apps, a useful addition for merchants who want mobile access without moving to a paid tier.

Pricing

FraudLabs Pro uses monthly subscriptions rather than annual billing, so costs can be evaluated month to month but there is no yearly term to choose. The Micro plan is free and includes 500 queries per month, five validation rules, no grouping rules or sub accounts, 50 custom blacklists, and Standard Support. It is restricted to businesses with monthly sales under 25K USD, making it a constrained starting point rather than a general free tier for larger stores.

Plan	Price	Monthly allowance and included limits
Mini	29.95 USD per month	1,500 queries; 5 validation rules; 1 grouping rule; no sub accounts; 150 custom blacklists; Priority Support
Small	99.95 USD per month	5,000 queries; 10 validation rules; 2 grouping rules; 1 sub account; 500 custom blacklists; Priority Support
Medium	249.95 USD per month	25,000 queries; 20 validation rules; 5 grouping rules; 2 sub accounts; 2,500 custom blacklists; Priority Support
Large	499.95 USD per month	100,000 queries; 30 validation rules; 10 grouping rules; 4 sub accounts; 10,000 custom blacklists; Priority Support
Enterprise	1249.95 USD per month	500,000 queries; 40 validation rules; 20 grouping rules; 8 sub accounts; 50,000 custom blacklists; Priority Support

Mini is the lowest-cost paid step, but it offers only one grouping rule and no sub accounts. Small adds a sub account and expands rule and blacklist capacity, which matters for a merchant coordinating more than one account. Medium and above raise query capacity substantially and add sub accounts, while larger plans also expand grouping rules and blacklists; those tiers are better matched to higher-volume operations than to stores still testing demand. A free 14-day Medium trial gives merchants a chance to evaluate a higher-capacity tier before subscribing. The pricing page also cites 1,500 included transactions per month, distinct from the plan-specific query allowances, so buyers should account for both stated measures when estimating fit.

Platforms

FraudLabs Pro supports web, Android, iOS, and API access. Its online channel focus fits e-commerce payments, with integrations for several major storefront systems and a REST API for custom connections.

Who it's for

This is a sensible fit for startups through enterprises that accept online payments and want to reduce fraud exposure with configurable order checks. Small sellers can begin on Micro if they meet its sales ceiling and can work within 500 monthly queries and five validation rules. Merchants with higher volumes, multiple operating accounts, or a need for more grouping rules should consider paid tiers. Businesses seeking a chargeback guarantee should look elsewhere.

Pros and cons

Pros: Wide validation coverage combines order, identity, device, and network signals; this gives merchants more than a single payment-field check.
Pros: Storefront modules plus a REST API offer both ready-made and custom integration paths.
Pros: The free Micro tier includes mobile apps and 50 custom blacklists, useful for eligible lower-volume businesses.
Cons: Micro is capped at 500 queries monthly and sales under 25K USD per month, limiting its usefulness as a long-term option for growing shops.
Cons: Paid plans add meaningful cost as volume rises, and the service offers no annual subscription term.
Cons: It provides recommendations, not a chargeback guarantee, so merchants retain the risk of losses and disputed transactions.

Alternatives

IPQualityScore Fraud Prevention is worth comparing for merchants who want a freemium alternative with 1,000 monthly lookups on its free plan, ten custom rules, and Android, iOS, API, web, and self-hosted platforms.
Stripe Radar may suit businesses already using standard Stripe payments that want its free Radar Lite fraud prevention for card payments and card testing at no additional charge.
Ravelin is an option for businesses seeking a tailored fraud platform, with custom pricing and a demo-led sales process.
Vesta is another paid alternative.
DataVisor Fraud Platform may suit enterprises looking for a custom platform and willing to request a demo.
Sift Payment Protection is a paid alternative with pricing handled through contact.
Mastercard Decision Intelligence is a web-based paid alternative with sales-contact pricing.
Braintree ACH Direct Debit is a different kind of option: eligible U.S. merchants can use standard ACH processing at 0.75 USD per transaction, capped at $5.00.

Verdict

Choose FraudLabs Pro if your online store needs configurable transaction scoring, broad validation checks, and an integration path that fits its storefront or API setup. Its free tier is useful for eligible small sellers, while larger query allowances and account controls make paid plans better suited to higher volume. Look elsewhere if you need a chargeback guarantee or a free plan without the stated sales and query constraints.
