If you find that a customer has paid too much, you can quickly and easily refund the overpayment in KashFlow.
Issuing the Refund
To start, go to Invoices > Select the invoice. The overpaid amount will be displayed at the top. To refund it, scroll to the Payments section at the bottom of the invoice and press Add Payment.
A negative figure to the amount of the overpayment will already be prepared for you. If required, modify the figure here so that it matches the refunded amount. You should also change the date to the date that the money left your bank account.
Please select the bank account that you paid the money out from as well as the payment method you used to refund the customer.
When ready, click the Save button. A payment line will appear, showing the money as having been paid out. If the overpayment is refunded in full, the invoice status will change to Paid.
