When we printed the checks we neglected to say “not double sided” so now we have the checks printed but not posted. Is there an easy way to reverse what we did instead of void all the checks?
You should be able to use Process Payments again to reprint the checks. It will ask you what the last correct check number was (I believe entering a zero here will tell Epicor none of them were correct) and what the currently loaded check number is. Once you reprocess and reprint the checks, it will reassign the new check numbers to the payments.
