Contractor Invoice vs Proposal: What's the Difference?

A proposal is sent before work begins. It outlines scope, price, and terms. When a client signs it, it becomes a contract. A invoice is sent after work is completed.

The right workflow: Send proposal → client signs and pays deposit → do the work → send invoice for remaining balance.

If a client disputes a charge and you only have an invoice — no signed proposal — you have a much harder time proving the client agreed to that price.
