Doesn't work, a complete mess – Cashier | Point of Sale (POS) Register Review

Was trying to find an app to use during our upcoming garage sale, but every time I add a category to the inventory I get an irrecoverable server error. I deleted the app, and downloaded a second time for the same outcome. I suggest trying an app that actually works since this one is a mess.
