It would be very helpful if I could have multiple Square Accounts on my phone and be able to toggle between them for sales. Signing in and out for each sale is not effective and takes too much time.
As I see this is your first post let me welcome you to the Square users forum.
May I ask why are you signing in and out of different accounts for Each transaction? I am trying to understand why you do not have one account with all your items in it to just sign in to the one account, and why you have more than 1 account for a Location?
