Frequently asked questions
How does Signifyd price its service?
Signifyd charges a percentage of the order total when an order is approved; the percentage varies by vertical, product mix, order volume and average ticket price. There is no charge when an order is declined for fraud. Exact pricing comes from a custom quote after an assessment of your current declines, chargeback losses and approval-rate targets.
How does Signifyd decide whether to approve an order?
It collects session data such as IP, behavior and transactional detail, then applies machine learning over a contextual layer that includes forensic data and 150+ out-of-band ID sources. The combined picture produces a fraud decision, and the liability shifts from the merchant to Signifyd under its Guaranteed Fraud Protection.
What does Signifyd's financial guarantee cover?
Signifyd offers a configurable financial guarantee against chargebacks, ranging from fraud-only protection to a total chargeback liability shift. The company distinguishes this from a performance SLA that only promises an approval rate without an incentive to beat it.
How long does implementation take?
Signifyd markets the quickest time to value in the category and supports plug-and-play connectors plus REST APIs, webhooks, JavaScript tags and mobile SDKs for custom builds. Merchants on pre-built platforms typically go live in a few weeks; complex custom stacks take longer.
Which systems does Signifyd integrate with?
Pre-built order integrations include Shopify, BigCommerce, Adobe Commerce, Salesforce Commerce Cloud, NetSuite, Vtex, Miva and Accertify. Payment integrations include Adyen, Stripe, PayPal, Square and WorldPay. Custom work is supported through REST APIs, webhooks, JavaScript tags and SDK libraries.
What support is included?
Signifyd's customer success team provides 24/7 online support and access to a comprehensive FAQ, and existing customers can raise issues through the support portal. Every order also gets an expert re-review option: declined orders can be resubmitted with extra detail for review by a certified fraud expert.
