Signifyd

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.

Signifyd will quickly burn the multi-million dollar business you’ve built. They promised protection from fraud and increased acceptance of orders, instead, they took a LARGE CHUNK of our money, blocked THOUSANDS of legitimate orders from loyal customers, and completely wrecked our reputation. No warning, no explanation. Just cancellations and total chaos. We were left to fix everything manually and apologize for their mistakes. They charge a fortune, cancel real orders, and disappear. We lost sales, customer trust, and years of work. Skip the headache. Accept chargebacks yourself, it's cheaper, and without the total nightmare. Do yourself and your business a favour - avoid these scammers at all costs.

Wrongly turned off store syncing without our permission. Was advised it was because we didn't use the service, but upon further checking we did have it turned on and using it. Asked support to restore it and fix syncing transactions for guarantee, and they advised they did, but still not working.

Fraudulent company. They don't deliver on their promise. They say Gurantee Badge is covered. When you submit the claim they deny it with some bogus code reason. Stay away.

We paid Signifyd thousands of dollars over two years and every time we had a case of fraud that they supposedly guaranteed, they turned us down and refused to reimburse us. Basically we paid them a fortune and still had just as much fraud so we lost even more money. Read the fine print very carefully because they have so many loopholes in what they actually cover they will never reimburse your chargebacks.

This company is a scam. They charge me every month for the service but when I receive a charge back on an order that they said was okay to ship they always have an excuse on why it isn't covered. Not sure what I am paying for? Avoid this scam at all costs.

BEWARE! We are a very high volume retail store + Shopify Plus Merchant, and work with quite a few applications, even during early beta stages. We have been a long time user of Signifyd, basically using their rating system to make final decisions on orders that were borderline cases. Recently we decided to try their guarantee option on some higher valued orders. Unfortunately we received a chargeback for one case that was approved + guaranteed. We followed all the guidelines and opened a reimbursement case, and this is where their true colors show. 1. 6 days after filing our case, we never received a response from their team. We sent 2 followup emails with no responses as well. 2. On the 9th day we checked the case again, and they labeled the case is ineligible because it has been past 30 days since they asked for more information. How does that make sense? We only opened the case 9 days ago. Now If you are going to use their system to just to just review information, the platform works fine, but if want to use their chargeback guarantee option, we highly recommend to stay away. This application is definitely too good to be true.

Everything started perfectly working for the 1st couple of months, however when 4 chargebacks came, they payed them off correctly but the system simply started to red flagg more than 50% of my orders. When i contacted customer support they said its because the system learns from the fraud orders, Maybe it has to do that my store is in Mexico, but they did told me they were able to provide the service perfectly in my country.
