Try WylloFree screening; guarantee from $250/mo (Shopify)

Wyllo, called NoFraud until March 2026, is an ecommerce fraud and abuse prevention platform that screens orders and can guarantee fraud chargebacks on orders it approves. It suits online stores on Shopify, BigCommerce, Salesforce Commerce Cloud and Adobe Commerce. On the Shopify App Store, screening is free for up to 100 orders a month, and guarantee plans start at 1% of revenue with a $250 monthly minimum.

NoFraud is now Wyllo

NoFraud announced the acquisition of Yofi AI, a return fraud and policy abuse detection platform, on 8 October 2025. On 19 March 2026 the combined company rebranded as Wyllo.

nofraud.com now redirects to wyllo.ai. Merchants still sign in at portal.nofraud.com, and the Shopify app keeps its NoFraud web address under the Wyllo name.

Our takeWyllo suits online stores that want fraud decisions with a financial backstop: approved orders that turn into fraud chargebacks are covered under the guarantee plans.

Small Shopify stores can start free, but the guarantee tiers take a share of revenue with monthly minimums, so model the cost against your chargeback losses. The 2026 rename means you will still see NoFraud addresses for login and the API.

Why we rate itCovers fraud, returns and policy abuse with a guarantee option and published Shopify prices.

The catchRevenue-share pricing with minimums, and the guarantee is limited to fraud chargebacks on passed orders.

Trade-offs

Friction report

Trade-offs to know before signing up.

Time to value
Minutes to install on Shopify (vendor says under 5 minutes); tuning rules takes longer.
Scale breakpoint
More than 100 orders a month ends free screening; above $50K/month revenue moves you to custom pricing.
Walled garden
Low: apps for major platforms plus a direct API.

Still a fit?

If none of these block you, start on the free plan.
