Outstanding Fraud Protection with Exceptional Results We've been selling online since 2006, and using this fraud protection platform has been one of the best operational improvements we've made. Since implementing it in 2020, we've seen a significantly higher percentage of verified transactions and approved orders while maintaining an extremely low number of manual reviews and chargeback requests...

— Emotiva Audio Corporation

Wyllo has been a reliable fraud prevention solution for our Shopify store. The integration was straightforward, and it has helped us reduce fraudulent orders while keeping our review process efficient. Like any fraud tool, there are occasional cases that require manual review, but overall it has been a valuable addition to our operations and has saved our team time.

We have been using Wyllo (No Fraud) for 13 months, and we find the tool easy to navigate and the reporting straightforward. The Wyllo team is an excellent partner; they are very open to feedback, listen to our needs, and consistently offer solutions for unique scenarios.

We've been using Wyllo (formerly NoFraud) for several years and have had a great experience. The platform has helped us reduce fraud and chargebacks while allowing legitimate orders to be approved with confidence, which has been a huge benefit for our team. The process is straightforward, easy to manage, and their support team has always been responsive and helpful whenever we've had questions or...

Wyllo (NoFraud) has been a standout addition to our ecommerce technology stack. Their platform gives us added confidence in every order we process, helping us protect the business while continuing to deliver the level of service our customers expect. The implementation was smooth, the Chargeback Guarantee brings meaningful peace of mind, and the visibility behind fraud decisions has been especial...

— Benchmade Knife Co.

We previously used another service for fraud protection and now have used NoFraud for about two years. I feel we get a slight edge with Wyllo (NoFraud) and have successfully had more orders pass. They are very receptive and responsive. I do wish the new dashboard showed the contact status, but I understand that's in the works, and in the meantime it is easy enough to switch to classic view. Overal...

— KEF CA

Wyllo/NoFraud has been great for our business. We have worked with the team there for a long time. We rely heavily on their platform with our Shopify ecomm purchases. Their technology has helped us reduce or potential losses. They are laos very quick to respond to question and/or needs.

— Hotel Collection

Wyllo has been such a valuable tool for our business. The data insights alone have prevented fraud and helped us to make informed decisions about return and shipping claim abusers. Pair those insights with a phenomenal team that actually listens and works proactively to protect your business and you’ve got yourself a solution that makes your job easier.

— JAXXON

We have been using Wyllo(formerly NoFraud) for over 6 months now and it has greatly lighten our work load in fighting fraud and chargebacks! Worth the cost!

— Taramps USA

Shocking support and they cancel for no reason useless app do not use very dissapointed stay away other apps so much better

— Mearth New Zealand

This app is highly unreliable for tracking fraudulent orders. It often approves fraudulent orders and its screening process lacks coherence. We've encountered numerous chargebacks from orders greenlit by them. Their lack of accountability is concerning—they don't take responsibility for their mistakes. It's puzzling how a company named "No Fraud" struggles to properly screen fraudulent orders.

— AMEKANA

This app does not even work after installation. I keep getting this error when signing up for an account: You had some validation errors Phone Number is invalid There's not even any option to input a phone number during registration, so I can't even set up an account. What a waste of time

— SlipperPal

Deleting app. Too many orders approved by this company eventually come back as fraudulent.

— AMEKANA

I would not recommend, to many issues to get setup. Install script on all your pages what I think is to invasive to customer.

— DaRoAn

I do not recommend this application. I just got a bill for more that $3K. They lock you into a long term contact and the service is of low value, in our experience. It cost me $11K+ over a year’s time . I asked to cancel several times because I didn’t want to keep throwing my money away. And they refused. Bad customer support. Basically thieves.

— Rejuva Fresh

This app doesn't apply to small businesses. You wouldn't know that unless you install the app and try to enable the chargeback feature. (NoFraud requires a minimum of $50,000 in monthly processing volume for chargeback protection eligibility.) This equals out to $600,000.00 annually. I think this information should be available before people install your app.
