answer:It would depend upon the nature of the credit, wouldn’t it? After all, one presumes that it’s not a charitable donation to your cause on their part, or payment for goods received or services rendered. You’d know how to enter those credits, right? So, what is the reason for the credit? Was it an earlier overcharge? An accounting error on their part that had failed to return correct change or another balance due, or what? If the reason for the credit is a rebate for fuel purchases, then the credit would be applied to the fuel account, wouldn’t it?
