Ratings and reviews

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

I've been using this for three years(at the decision of my employer, not me), and it's been an awful experience. The reader constantly disconnecting at the most inconvenient times, and you may think that you can just quickly reconnect it and it's no big deal, right? Nope. Once it's been connected and subsequently disconnected(for some inexplicable reason), it won't reconnect to the phone until the device is forcefully "forgotten" in the app.

Everything was great! I used the app with MagStrip reader MAYBE 2 weeks and suddenly, this week l tried and there wasnt an option for use. I've tried EVERY WHICH WAY to get a LIVE PERSON and not an automated system, and yet there must not be any humans that work here! They deactivated my account for no reason. No warning. No way to resolve any issues. And now my funds are on hold for 90 days and MAY NOT EVEN BE RELEASED IN FULL by the end of it. Not only frustrating, but also UNACCEPTABLE!
