It depends on the accounting entries you want.  I'm not sure but a negative Receipt of Invoice might be possible.  You can write off the bottom line amount to a single GL account with a zero $ manual payment, or enter a credit memo with whatever details you wish then apply the CM to the invoice balance.

The zero (0) check would be my suggestion. You do a manual check using a check number that starts with APP and then select the invoice and offset with a GL account you decided on.

Thank you.

Thank you.

I would adjust the invoice to zero using invoice data entry.  Enter the vendor number and invoice number and if it exists you get a pop up and you can choose adjust.  You can code it to whatever expense account you need.  It makes it easier to track because if you go look at the detail it will show you adjusted to zero and did not pay it.
