If you receive one check for 2 different invoices, you can use either of the following processes to post the payment:
Example: The partial amount is for an AR Payment, the remainder of the check is for a Labor Credit.
Option 1:
1. Enter payment to folder, then remaining amount as non-AR to the same financial category as the credit memo.
2. Next create a non-AR payment for the labor credit using the vendor refund option, as well as a second negative line for the same fincat you use in the original payment.
This will create a $0 check but apply the amount to the open credit memo and you can apply the non-AR payment and the full payment together for the deposit.
Option 2:
Split the payment into 2 payments, one that you enter in the AR screen and the second in the Non AR Payment screen. Then you can deposit the 2 payments together.
