client paid too much money

I've got your back, @suzette2442.

You can record a refund for your client's overpayment using a Check or Expense. This way, it'll reduce your bank balance and offsets the client's overpayment.

First off, let's create a check or expense transaction to record the refund for your client. Here's how:

1. Click the + New button, then select Check or Expense.
2. In the Payee drop-down, choose the client you want to refund.
3. Select the bank account where you deposited the overpayment.
4. Choose Accounts Receivable from the Category drop-down.
5. Enter $2000 in the Amount field and necessary information.
6. Click Save and close.

Once done, you'll have to link the refund to the client's overpayment.

1. Click the + New button, then select Receive payment.
2. Select the same customer you used for the check or expense.
3. Enter the necessary information.
4. Put a checkmark on the check or expense you created under the Outstanding Transactions section.
5. Make sure the payment is equal to the open balance, then click Save and close.

Please let me know if you need clarification about this, or there's anything else I can do for you. I'll be standing by for your response. Have a great day.
