Business Works 12.5 - Mentor needed

I have a few questions for someone who has experience with Business Works 12.5 I have the version with the accounts receivable options only. No ledger is available.
I'm having a problem with posting receipts when they're paid ahead of the due date. When I receive a check and there is no invoice, I have to use the auto distribute function to be able to post the check. This creates an Open Credit that I can never get to go away even after the invoice is created. There will be a zero balance on all reports, but an open credit (for the amount they paid ahead of time) will always show up on Aging Reports. Does anyone have any experience with this problem and can tell me how to clean up this problem.....thanks for any help.
