User Reviews

Stax Pay offers easy adoption, strong mobile payment capability, and solid data dashboards with remote access. However, repeated feedback cites stability problems (crashes, login loops), unreliable Bluetooth card reader connections, UX regressions after updates, and scenarios where in-app processing fails requiring workarounds via a browser or manual entry.
Pros
  • Intuitive and easy-to-use interface
  • Supports mobile payments anywhere with Bluetooth/mobile card readers
  • Robust dashboards and data reporting for tracking sales
  • Live dashboard access and remote visibility to run the business from anywhere
Cons
  • Frequent crashes and instability (login loops, timeouts) especially after updates
  • Unreliable card reader connectivity (Bluetooth pairing issues, readers not registering, inconsistent performance)
  • Update-induced UX issues and bugs (changes to checkout flow like tip prompt, general update regressions)
  • In-app processing failures that force use of a browser/web interface or manual entry

Takes multiple login attempts to just get in. Then you have to worry about card reader connection even if you had already connected it to Bluetooth. Once everything is logged in and connected it is a good system. But getting there is a hassle.

In general, this program has worked well for me over the past few years. However, with the most recent update, I’m not able to manually add customers any longer. Please help!

I use this app daily to take payments and I hate that it is my only option. I wish the developers would read the reviews and fix the horrendous app. You leave the app it quits, anytime I create a service item in the catalog it never saves it as a service sign.Please fix this.
