How to Write a Project Brief for Developers (With a Free Outline)

Short answer

A good brief tells developers who the users are, what outcome the product must deliver, the main journeys or screens, integrations, platforms, constraints, budget range and timeline, plus links to examples. With that, estimates are accurate and misunderstandings drop. A one-to-two page document is enough.

Brief outline

  1. Company and product in two sentences.
  2. Users: who they are and the problem they have.
  3. Goal: the outcome and how you will measure it.
  4. Core journeys: the 3–5 things users must be able to do.
  5. Features: Must, Should, Could, Won’t (yet).
  6. Platforms: web, Android, iOS, admin panel.
  7. Integrations: payments, maps, WhatsApp, accounting, CRM.
  8. Content and data: what you have and what is missing.
  9. Constraints: compliance, languages, regions, existing systems.
  10. Budget range and target launch date.
  11. Examples: three apps or sites you like and why.

Tips

  • Describe outcomes, not solutions (‘staff must see stock in real time’).
  • Include screenshots or sketches.
  • State what is out of scope.
  • Name one decision-maker.
  • Share the brief with two or three vendors to compare questions and quotes.

What to expect back

  • Clarifying questions
  • A scope summary and assumptions list
  • A fixed price or hours range
  • A timeline with milestones
