I had to void an accounts payable check in Ver. 9, which included only one invoice. I actually wanted to pay two invoices with one check. After voiding the check I can't find the original invoice to pay. Do I have to re-enter the invoice?
You would have to reenter the invoice. The original invoice was paid by the original check that you voided. So now it is just as if you were back at the beginning. Enter both invoices and then print checks, the check will print for a combined total of both invoices.
