Ratings and reviews

I only am using the app on my android due to failure of my Square Reader, which was glitchy and quit working. Not only did I lose sales, but it was out of the 1 year warranty, so they told me to buy a new machine. No thank you Square! I will take my business elsewhere, high volume but low sales pushed the credit card average cost to almost 4.7%, No Thank You!

Difficult to use. When I switch to the keypad, there is often an amount. I have to close and restart the app to get it to clear. My business is mobile. I have to charge tax based on the work location and type of job. I can find no way to accommodate this in the app. I usually end up clearing all taxes and charging the total calculated externally. I've already tried the suggestions and my app is always kept up to date.

Would be great if it wasn't for so many bugs. Switched my business to square and I've regret it since. You can't create new clients at all, it forces you to import them from contacts which doesn't work half the time, and trying to create a customer in the app just gives error codes. Often invoices won't load or send, and the custom items rarely show up as theyre supposed to. Due to bugs it often takes hours to write an invoice with a paragraph in it
