Wyllo

We were a NoFraud customer for many years and stayed on through the transition to Wyllo AI. Unfortunately, the service declined after the rebrand — decision accuracy on orders was noticeably worse than what we'd come to expect, and we ultimately moved to another fraud-protection provider.

The reason for this review, though, is what happened on the way out. While closing out our remaining open disputes, we deliberately set the app to test mode so we would not be charged for orders, keeping it installed only to retain access to the case management tools. Wyllo then reactivated our account to live mode without asking us. We learned of it from an email sent by a senior member of their customer success team after the fact, telling us their technology had detected that our services "may have been accidentally disabled" and had already re-enabled them. It was not disabled in error — it was off by our deliberate choice — and at no point before reactivating did anyone ask us whether the change was intentional. Orders were charged in the meantime.

The money is not the point. The point is that a vendor changed our store's configuration and turned a billable service back on based on their own assumptions, informing us only after it was done. That is not how a trusted partner behaves. We have reported the incident to Shopify and uninstalled the app.

If you use this app, watch your billing closely — especially if you ever pause or test-mode the service.
