• Go to the Sales module.
• Hover over Invoices on the top modular bar and select Invoices from the dropdown.
• Click the Payments Received section on the Invoice Overview page and click the Delete icon.
• On the Delete Recorded Payment page, choose the Dissociate & Add as Credit option.
• On the following page, click Dissociate & Add as Credit.

Now, this payment will be stored as credit for the customer.
