You can apply an AR credit to an existing AR invoice balance through Tasks - Adjust Receivables.  For the customer, you will see the AR Credit and if you highlight it, you can see an "Apply" button becomes available.  Click the Apply button and it will then show a screen of open invoices.  You pick the invoice that you want the credit applied to.  

Hi Rhonda, when I go in to Adjust Receivables and highlight the credit the "Apply" button does not become available.

Hi Cesposito,

It sounds like when you say "AR Credit" - which is a type of adjustment in Adjust Receivables - you mean a credit or negative invoice.

Here are the instructions to use credit invoices in Accounts Receivable:

Thanks!

That is correct.  Thank you for the information.  I was able to clear them.
