Signifyd
The reviews are overwhelmingly positive about Signifyd’s fraud prevention, chargeback protection, and ease of integration. Many merchants say the app has reduced manual work, improved approval rates, helped them scale with more confidence, and provided a seamless setup experience. A recurring strength is the support team: reviewers frequently praise specific account managers and customer success staff for being responsive, knowledgeable, cooperative, and proactive in helping with onboarding, plan changes, and fraud-related issues. The negative reviews focus on billing, reimbursement, and support reliability. Several merchants report delayed or missing responses from support, difficulty getting claims reimbursed, and frustration with claims being denied or handled through opaque rules and loopholes. Others mention plan changes or account closures without sufficient notice, syncing issues, and cases where legitimate orders were blocked or canceled, which hurt sales and customer trust. Overall, the app is seen as highly effective when it works as expected, but some users feel the company’s support and claims process can be inconsistent or overly restrictive.

We've used this app since 2015. It was set up to only look at direct Shopify store orders and ignore eBay orders, PayPal payments and other non-Shopify direct sales. All was fine until we received our June 2026 bill, which was about 30% higher than normal. Come to find out, they stopped filtering out these orders. By the time we realized what was happening, we could not cancel the orders older than 30 days. We tried 4 or 5 times to contact the support people, but they never responded. For now, we are manually canceling these orders, but I think we will just remove the app since Shopify now has their own fraud detection and it's free. 8/23/2026 Still have not heard any reply from Signifyd. I also noticed a few days ago that when a customer cancels and order, Signifiyd does not cancel it in their system, so it seems they will charge you whether or not you process the order (unless you manually cancel it).
Working with Signifyd and Spencer our assigned team Manager has been an absolute dream. Spencer is consistently cooperative, responsive, and incredibly easy to partner with. Every challenge we've faced (from fraudulent orders to chargebacks and everything in between) has been handled with complete ease with Signifyd. We just upgraded our platform and plan as we have been with them for 5 years and things are evolving daily and it was time and were happy with the changes ahead for the future of our company lets go ready for another 5.

Working with Spencer at Signifyd has been a great experience. Our store has recently seen an increase in chargebacks, so we knew we needed to make adjustments to ensure we had stronger protection in place. Spencer helped guide us through switching to a new plan that better fit our current needs and risk level, and he made the entire process extremely smooth from start to finish and promptly answered any and all questions we had. We highly recommend working with Signifyd to ensure protection for all orders from your store!
We’ve partnered with Signifyd for several years now, and the experience has been consistently positive. Their team is highly responsive, easy to work with, and always ready to provide support when needed. The Complete Chargeback Protection program has been especially valuable; it gives us confidence that our business is safeguarded, no matter how a transaction turns out. Highly Recommended!
