The case ofnegative Cash App balanceis quite different. It can be caused by a number of factors. Let’s understand it with an example. Suppose you have had dinner at a restaurant. You asked for the check and made a payment but left the tip unpaid (as mentioned in the check). If Cash App charges your account with a tip while processing the payment and your balance is insufficient, your Cash App balance can be negative. However, your balance will not go negative immediately, but it can do so in the future. If you have faced any issues related to negative Cash App balance , you can contact Cash App Customer Service Number.
