Another question - this is different to a situation in which he was offered it for $1599 and then they accidentally put $599 via EFTPOS (leaving off the "1") isn't it? In that hypothetical case they can chase him up for another $100 am I right?
I'm guessing that you're asking do you have to front up with another $1000 and not $100?
From having put this question before a lawyer before I am pretty confident in saying yes, they can go after you for the extra $1000. If the invoice states $1599 (which is the amount you agreed to pay), and you only paid $599, you still have a debt to them of $1000, which they can seek. Same thing the other way - your invoice says $10, and they accidentally put $100, you can go back, as I'm sure you would expect!
IMO it's the biggest problem in not having your eftpos integrated into your POS - if you're relying on people to enter the correct amount into the eftpos terminal, mistakes will happen.
