QB2005 how to "un apply" discount?

Leaving the customer with a $3.95 balance due?

Meaning you issued a credit memo to the customer, and applied it to the underpaid invoice?

Ummm... if you gave the customer a credit for the underpaid amount, then in effect you *DID* 'forget' the $3.95. If you've decided that you want the unpaid balance to remain in effect, just go to the original credit memo and void it.

A credit to the customer?

If you know what you've done, you can un-do it. IMO the problem is that you are not quite sure exactly what you did. You speak of 'receiving payment for several invoices', leading me to think you are dealing with a customer credit. But then you mention 'I wound up with a credit or discount for $712.27' -- making it sound as if it is a vendor issue?

Post back with details.

Yes.

I never wrote the credit memo. What I was looking for at the time was a way to accept and deposit the entire payment, but postpone the invoice that was short, while I went back to the customer for the correct amount. I thought the credit button I pushed was a way to do that. Maybe it was, I just needed to follow through with a credit memo and then reenter the payment for that invoice when the correct amount came in?

I couldn't find it, so I don't know. I'm pretty sure it happened on

BTW, this is 2005 Pro, in case it matters.

I had a check paying several invoices from one customer. It was short $3.95 because one item on one invoice wasn't paid. It's the first time this has happened, so I wasn't clear on procedure, Quickbooks popped up a window suggesting things to do about the discrepancy, I didn't take the option I should have (write it off), I took the other one, which I don't recall exactly, but I believe issued a credit, Then when I tried to fix things on 11/27 I must have pushed the wrong button, somehow winding up with the $712.27 (an amount that doesn't match any of the invoice amounts, BTW).

I needed to do some more bookkeeping, so yesterday I restored from 11/27 backups (fortunately not much bookkeeping since then), went back to that received payment, unapplied it, then reapplied, this time writing off the $3.95 I hope there isn't still a credit floating around somewhere, at least it doesn't appear on the receive payment for that customer now.

I don't know what I would have done if there were a significant amount of bookkeeping work since 11/27.

What I could have used is a log of every change, so I could have gone back to the error, corrected it, then automatically re-entered everything since. Of course there should be another log somewhere that would show that I did that. For the auditors.
