A short document a client prepares describing what they need, why, and any constraints, giving professionals enough to scope and price the work.
A project brief is the short document a client writes to explain what they need: the goal, the audience, the constraints, the budget, and the deadline. It gives professionals enough to scope the work accurately and quote without a dozen clarifying emails.
For buyers, a good brief is the single highest-leverage thing you can do to get better work and comparable quotes. Vague in, vague out — “I need a website” gets you wildly different bids, while a clear brief gets you proposals you can actually compare. For sellers, a client with a real brief is usually a client who’s serious and easier to work with; when one arrives without a brief, helping them write it is often the first valuable thing you do.
The brief doesn’t need to be long — a page beats ten. Focus on the why and the constraints, and leave the how to the professional; over-specifying the solution often boxes out the best ideas. Our project brief template covers the essentials without the bloat.
