How to present it

Trades quotes are compared side by side, often on a phone, so the total has to be obvious and the scope written in words a homeowner uses. Materials, labour and what happens if the wall is not what you expected, each on its own line.

A fixed price for the defined job and optional lines for the things clients always ask about mid-way: the extra bed, the second coat, the seasonal visit. When they are on the page from the start, nobody feels upsold.

Deposit and payment stages belong in the proposal. A client who has accepted a page that says "40 percent to book, balance on completion" has agreed to it, and the signed record proves it.
