The verdict in three sentences
The brief is the document that protects your budget: without it, every "extra" request turns into an unexpected invoice. A good brief in 2026 fits in 6 to 10 pages and covers eight mandatory sections, including site map, prioritized features (MoSCoW) and measurable acceptance criteria. The code ownership and maintenance clauses are as decisive as the design.
The mandatory sections of a brief
Here is the standard structure of a complete brief, with the expected content and the common pitfall of each section.
| Section | Expected content | Pitfall to avoid |
|---|---|---|
| Business goals | Targets, KPIs, conversion goal | Vague, unmeasurable goals |
| Site map | List of pages and hierarchy | Pages added mid-project |
| Features | Payment, multilingual, forms | Unfrozen scope |
| Content | Who supplies text/photos and when | "Agency will write" uncosted |
| Design | Brand guidelines, 2 mockups max | Endless back-and-forth |
| SEO | Keywords, tags, structure | SEO forgotten at the start |
| Acceptance criteria | Precise acceptance tests | Subjective sign-off |
| Schedule + ownership | Dated milestones, code/access clause | No ownership clause |
Each missing section is an open door to misunderstandings and add-ons. SEO and code ownership are the two most costly omissions.
The MoSCoW prioritization matrix
To avoid wanting everything in version 1, rank each feature using MoSCoW. This keeps the budget under control and lets you ship a useful batch 1 fast.
| Priority | Meaning | Showcase/e-commerce examples | Budget share |
|---|---|---|---|
| Must have | Essential for launch | Key pages, Wave payment, mobile | 50-60% |
| Should have | Important, not blocking | Blog, multilingual, analytics | 20-25% |
| Could have | Desirable if budget allows | Wishlist, reviews, chat | 10-15% |
| Won't have (now) | Deferred to batch 2 | Loyalty program, PWA app | 0% (batch 2) |
By freezing the "Must have", you get a firm quote. Anything sliding to "Could" or batch 2 avoids the 200,000 to 1,000,000 FCFA overruns mid-project.
Mini case study
Moussa, a restaurateur in Dakar, writes his brief with the agency. At first he wants everything: online booking, loyalty program, mobile app, blog, multilingual. The initial quote reaches 1,400,000 FCFA. Applying MoSCoW, he classifies only the showcase site + menu + simple booking + Wave deposit payment as "Must have" (650,000 FCFA), and defers loyalty and PWA to batch 2. He launches his site in 10 days for 650,000 FCFA instead of 1,400,000, validates the concept, then invests in batch 2 three months later with his first revenue. Immediate cash savings: 750,000 FCFA.

FAQ
Is a brief really necessary for a small site?
Yes, even a short one. A 4-to-6-page document is enough for a showcase site, but it freezes the scope and prevents mid-project requests from inflating the bill by 30 to 50%.
What is the MoSCoW method?
It's a matrix that ranks features into Must, Should, Could and Won't have. It focuses 50 to 60% of the budget on essentials and defers the rest to batch 2, keeping the project affordable.
What should acceptance criteria contain?
Precise, measurable acceptance tests: "Wave payment confirms the order in under 10 seconds", "the site loads in under 3 seconds on mobile". Without them, sign-off becomes subjective and conflict-prone.
Should I include a code ownership clause?
Absolutely. Specify that the code, domain and access belong to you on delivery. This one-line clause saves you 200,000 to 500,000 FCFA in rebuild costs if you switch providers.
Who writes the brief?
Ideally you and the agency together: you bring the business goals, the agency structures the technical side. Count on 2 to 3 days for a solid document — an investment that avoids weeks of dispute.
