Invoice from a contractor after completion

What is the name of your state? California

Hi There,

I have just received an invoice from a contractor more than 2 months after the job was completed. The invoice only says that it is a correction (to some discount they had given me which they never really did give any) and now I owe more money to them.

I have already paid them in full based on the contract. I paid them as soon as the job was completed. Can they really send this kind of invoice? What are my rights?

Thanks,
GapHari

You don't need to pay anything more than what is required by a contract.
