A clear brief is the cheapest way to improve any project. It helps suppliers understand what you need and lets you compare their proposals fairly.

What to include

  1. About the business: what you do, who you serve and what makes you different.
  2. Goals: the results the site must achieve, such as enquiries, bookings or sales.
  3. Audience: who will visit and what they want to know.
  4. Scope: the pages and features you expect, and what is out of scope.
  5. Content: what you already have and what you need help creating.
  6. Design: examples you like and dislike, brand assets and tone.
  7. Technical needs: integrations, languages, accessibility, hosting preferences.
  8. Timeline and budget: a date and a range, even if approximate.
  9. Decision process: who approves each stage.

Tips

  • Describe problems, not only solutions; suppliers may suggest better answers.
  • Be honest about budget so proposals fit it.
  • Share analytics or customer questions if you have them.

What a good proposal gives back

It should restate your goals, list deliverables, show a process and timeline, explain assumptions and give a price or range with what is and is not included.

Frequently asked questions

Is a long brief better?

No. A clear one or two pages is enough. Include what matters and be specific.

What if I do not know my budget?

Give a range or ask suppliers for options at different levels so you can see what each adds.
