He can choose what he wants to do.
If he paid not enough:
- He can get his money back (minus miners fee and our provision - 0.45%)
- he can pay the missing amount
If he paid too much:
- He can get his overpaid money back (minus miners fee and our provision - 0.45% for the overpaid money) if it will be more than 0
- He can leave it for future payments for the same customer (if customer chooses this option)
In both cases this is your money! Our automated system will pay it back to the customer if needed, but it stays on your account until resolved.
So you can pay it out at any moment if you want to.
