What a proposal is for

A proposal has one job: to make it easy for somebody to say yes. Everything that does not serve that is padding.

The reader is busy and probably comparing. They will read the first paragraph, look at the price, and skim the rest. Write for that reader rather than for the one who studies every page.

It is about their problem, not your company. Most proposals open with a page of history, team photographs and a mission statement, and the reader skips all of it. Your credentials belong near the end, briefly, as proof rather than as introduction.

A proposal is a summary of a conversation you already had. If you are writing one without having spoken to the client about what they need, you are guessing, and the proposal will read as a guess. Everything good in a proposal comes from the questions you asked beforehand.

Length is not value. A twenty page proposal does not look thorough, it looks like a template. Two to four pages for most work, and the shortest version that answers everything is the best one.

Send it fast. A good proposal in two days beats an excellent one in two weeks, because interest fades and competitors reply.

One more thing that matters more than the writing. Only write proposals for work you have qualified: a real budget, a real decision maker, a real timeline. Writing detailed proposals for people who were never going to buy is the largest time waste in small business, and it feels productive.
