Or more specifically, pay for what you say you'd pay for in the contract. If it was a time and materials contract, pay the man for his T&M. I've spent way too much of my career dealing with nasty clients who signed a T&M agreement and then stopped paying when they didn't get the next Facebook / Google / Amazon. Not my effing problem that their expectations weren't in the realm of reality and the contract was based on time units not their pie-in-the-sky dreams. If they'd wanted a contract based on their pipe dreams, chances are I wouldn't have signed it OR I would have put in verbiage to make sure they couldn't screw me in the end.
