The verdict in three sentences
A spec document (RFP brief) turns a vague idea into comparable bids: without one, two quotes for the same site can differ by 1 to 3x. Investing 3 to 8 days of writing cuts price spread by roughly 40% and halves acceptance disputes. For an SME, a 8 to 12 section brief is enough to steer a 6,000-15,000 EUR (excl. VAT) project.
The must-have sections of a brochure-site brief
A good brief is not a novel: it is precise, quantified and testable. Every section should let a vendor quote without calling you ten times.
| Section | Expected content | Writing time |
|---|---|---|
| Context & goals | Market, audiences, KPIs (leads/month) | 0.5 day |
| Functional scope | Pages, forms, blog, multilingual | 1 day |
| Sitemap | Menu, depth, 8-15 pages | 0.5 day |
| Brand & design | Logo, colors, visual references | 0.5 day |
| Content | Who writes, who supplies visuals | 0.5 day |
| Tech & SEO | CMS, hosting, performance, meta tags | 1 day |
| GDPR & legal | Cookies, forms, host | 0.5 day |
| Acceptance & criteria | Test cases, browsers | 0.5 day |
| Budget & timeline | Envelope, milestones, penalties | 0.5 day |
Budget, timelines and the impact of a good brief
The brief directly drives price and risk. Here are 2026 orders of magnitude for the European market.
| Item | Without a brief | With a structured brief |
|---|---|---|
| Spread across 3 quotes | x1 to x3 | x1 to x1.6 |
| Change orders mid-project | 3 to 6 | 0 to 1 |
| Acceptance disputes | frequent | rare |
| Typical brochure-site budget | 6,000-18,000 EUR excl. VAT | 6,000-15,000 EUR excl. VAT |
| Delivery lead time | 10-16 weeks | 8-12 weeks |
| Writing cost | 0 EUR | 0 EUR (in-house, 3-8 days) |
Acceptance criteria are the most neglected and most profitable part: define what triggers the final payment (load time < 2.5 s, tested forms, Lighthouse score > 90, mobile compatibility).
Mini case study
Marc runs a 35-person industrial SME in Nantes and wants to rebuild his site. With no brief, he gets three quotes: 7,000, 12,500 and 19,000 EUR excl. VAT, all incomparable. He spends 5 days writing a 10-section brief. New quotes: 8,500, 9,800 and 11,200 EUR excl. VAT, spread down from x2.7 to x1.3. By picking the 9,800 EUR offer instead of absorbing an average 2,500 EUR change order, he saves about 3,700 EUR and avoids two acceptance rounds. The return on his 5 days is clearly positive at signature.
FAQ
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
How long does it take to write a spec document?
Between 3 and 8 working days for an SME brochure site, depending on page count and content maturity. A reusable template halves that time on the next project.
Is a brief worth it for a small 6,000 EUR site?
Yes. Even a short one (4 to 6 pages) prevents change orders and secures acceptance. On a tight budget, each 1,500-2,500 EUR change order hurts.
Who should write the spec document?
The client side leads (goals, content, budget), ideally with a neutral vendor for the technical part. Do not let the chosen agency write the brief it will quote against.
What goes into acceptance criteria?
Binary tests: target load time, browser compatibility, working forms, performance score, GDPR compliance. Each criterion gates the final payment.
Do I need a brief for a simple visual refresh?
A lightweight brief covering brand, sitemap and acceptance is enough. But spell out SEO carryover so you do not lose your existing rankings.
