Personally i think it speaks for the company, they overpaid you and the gracious thing to do would be to say next job you do for them, they will deduct amount owed. I just had a situation where i uploaded wrong part of receipt, credit card not one showing what I ordered. i couldn't find it when called, sure it got thrown away.
Scheduler said we'll send report through, you've been doing this job for years, first time this has happened,
but I can't promise the client will accept report without proper receipt, they did have amount. We took our chances. I got a call today, report was accepted. I will get paid...won't make that mistake again.
Live consciously....
