Negative balance on customer

Welcome to the Community, nesvt.

I have the information you need to fix a negative customer balance in QuickBooks Online.

A negative balance on your customers indicates that you owe an amount to them. You can clear the balance by creating a refund, which depends on various scenarios.

To begin with, let's enter a credit memo to create a refund if the customers have already paid their invoices. Here's how:

1. Click on the +New button, then Credit memo.
2. Choose the appropriate customer in the Customer field.
3. Fill in the Date, Amount, Tax, and Product/Service.
4. Select Save and close.

After that, proceed to these steps to process the refund:

1. Click + New, then Expense.
2. Choose the appropriate customer in the Payee field and the bank the money is being refunded in the Payment account field.
3. Pick the Debtors account (Accounts receivable) in the Category field, then enter the amount in the Amount field.
4. Select the appropriate tax in the Tax field and click Save.
5. After that, head to the +New button, then Receive payment.
6. Provide the Customer and Payment method and the account in the Deposit to field.
7. Ensure to have a 0 amount as it will cancel out each other, then Save and close.

On the other hand, you can refer to this article if you need to issue a refund for a product/service that didn't satisfy customers or overpayment: Record a customer refund in QuickBooks Online.

Moreover, you might want to review this material to ensure your record matches your bank or credit card statements and prevent unwanted changes within your book:

If you do not real owe the customer money then you may have simply applied the customer payment incorrectly. Maybe the payment was assigned to the customer and not to the invoice or maybe the payment was assigned to the wrong customer.  If the payment was assigned to the wrong customer then the wrong customer will have an over payment resulting in a credit balance.

There could have also been a duplicate data entry.  Maybe you forgot you already accepted the payment against the invoice and then did it again.

The other thing that could have happened is that the payment was not entered as a payment to the invoice but simply as a deposit which skips a step.

If this is a recent occurrence it should be pretty easy to find by backtracking against your most recent deposits (customer payments).
