A client asks for a fixed price. The vendor writes a spec, quotes a number, and both sides sign it feeling like they’ve eliminated risk. Six weeks in, the client wants a feature that wasn’t in the spec, the vendor calls it a change order, and the relationship that started as a handshake is now a negotiation over what “originally scoped” meant. That’s not a fixed price project gone wrong. That’s what most fixed price projects actually look like once real requirements meet a document written before anyone had built anything.
