Granted incredibly unlikely, but doesn't that open the possibility of:
* Rip off developer
* Hire incredibly expensive legal team/legal buddy[1] to find small enough loophole in contract
* Bill developer for cost of legal as well as rip them off
* Profit?
[1] How do jurisdictions that auto-award costs handle contingency claims? Is "£0 if I lose, or £1M/hour if we win" a legitimate billing rate? I can't imagine it could be.
I used to work for a company that put a late-payment clause right in the contract. If you didn't pay us you were on the hook for a fee plus interest on the outstanding balance. So essentially it was like owing money to the IRS.
As far as I know nobody ever gave us trouble about payment.

This is so common in the business world -- terms -- that there's a short hand minilanguage for describing your terms on invoices, purchase orders and contracts.
