Customer paid invoice twice

[Harty]

A customer paid an invoice twice by EFT.  The first payment has been reconciled. How do I put the second payment on as a credit to go against future invoices?

Hi @Harty 

Typically, you would follow the below process to create an extra payment against that invoice which in turn put that invoice into credit:

1. Go to Sales>>Recieve Payments
2. Choose the Customer and bank account
3. Select Include Closed Sales
4. Apply the payment to the invoice as you normally would
5. Ensure that the Total Applied matches the Total Received and that you don't have a value in Finance Charge before selecting Record

What this process will do is apply the payment to the invoice again. As there is already a payment it will make the invoice show up as a credit in Sales>>Sales Register>>Returns and Credits so you apply it to a sale or pay a refund on it when required.

Do let us know how you get on and if you require further assistance.
