Hitting the Books --Dickeson

Counts? Overs and unders? To me that's a relic of a by-gone day. Scrap it. It's just an excuse for delaying the invoice. You can't possibly make up the few bucks you might gain or lose while delaying your invoice awaiting someone's guess of final count.

Does the invoice state explicitly when it's due? Thirty days means from the date the invoice issues. Give the customer a break. Compute it for them. Tell your computer to add 30 days to its issue date and print it in bold face right next to the bold face total due.
