Refunded a customer it showed up on the bank details then within a few minutes they reversed it as it was a invalid number so how do I change that on the invoice

Hello there,

You can allocate the refund amount shown in the for review tab using the Accounts Receivable. Then, create an expense transaction to record the refund amount to the customer. Here's how:

Create an expense transaction:

1. Click on the + New button.
2. Click on Expense.
3. Fill out the Payee, Payment account.
4. In the Category detail select Accounts Receivable.
5. Enter the amount and other details like GST.
6. Click on Save and close.

Then, go to the For review page and allocate the returned refund to the Account receivable account to math them to the expense.
