Ratings and reviews

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.

There's NO WARNING that we can't change the name of business or picture logo more than 3 times, so now the business name stayed WRONG!!! When I send a link to a customer for payment, it DOESN'T alert with an email that a request was sent!! When making a refund it DOESN'T VERIFY the amount before sending it!!! When making a partial refund, it shows the "TOTAL" amount of the transaction as "REFUNDED", not as partially refunded!!! And removed the ability to text with customer support!! 👎🏻🤦🏻‍♂️

Just had the worse Karen of my life yell at me because the square system was acting up. The app said it was accepted and gave me the green check with the last 4 digits of the card, confirming that it was accepted, only to then reset back to the register with the same total. So went back to the trans history and sure enough, there was no charge. So had to ask the client to process the payment one more time, only to show to trans history. So I logged in to the website and sure enough, system down.
