The verdict in three sentences
In 2026, a well-structured RFP brief is an Amsterdam communications lead's best negotiating lever: it lets you compare 3 agencies at strictly equal scope. Without it, price gaps reach 2.5x for the same brief, with no way to know why. Expect a target budget of 8,000 to 20,000 EUR and a 3-week response window to receive comparable proposals.
The structure of a brief that holds up
A good brief fits in 8-12 pages and covers 5 blocks: context, sitemap, functional requirements, technical/legal constraints, and scoring criteria. That last block is almost always missing and it makes the difference.
| Block | Expected content | Weight in success |
|---|---|---|
| Context & goals | Audience, KPIs, competitors | Frames the project |
| Sitemap | Pages and levels | Accurate pricing |
| Functional requirements | 12 listed requirements | Comparability |
| Technical constraints | GDPR, EU hosting, performance | Compliance |
| Scoring criteria | Weighted grid | Objective decision |
Explicitly list your 12 functional requirements (multi-step form, multilingual, blog, press area, booking, etc.): it's the only way to avoid ballpark quotes.
The weighted scoring grid
| Criterion | Weight | What you assess |
|---|---|---|
| Price | 30% | Total cost + recurring costs |
| Design / UX | 30% | Mockups, references |
| SEO | 20% | Method, redirects, performance |
| Timeline | 20% | Schedule, milestones |
| Total | 100% | Score out of 20 per agency |
With this grid, selection becomes defensible internally: each agency gets a numeric score, and "I just like this one" gives way to a traceable decision. Add GDPR constraints (EU hosting, cookies, DPA) as knockout criteria.
Mini case study
Thomas, communications lead at an industrial mid-cap in Amsterdam (130 staff), runs an RFP for a B2B showcase site. With a 10-page brief and his scoring grid, he receives 3 quotes: 8,200 EUR, 13,500 EUR and 20,800 EUR for identical scope, a 2.5x gap. The grid reveals the 20,800 EUR offer over-charges design with no SEO advantage. Thomas picks the 13,500 EUR offer (score 16.5/20) and saves 7,300 EUR versus the priciest, while keeping the best overall score.

How many pages should an RFP brief be?
Between 8 and 12 pages for a B2B showcase site: detailed enough to be comparable, concise enough to be read. Beyond that, agencies respond less or inflate safety margins.
What target budget should I state in the brief?
Show a 8,000 to 20,000 EUR range for an ambitious B2B showcase site. Giving a range avoids off-target proposals and speeds up agency screening.
How long should agencies get to respond?
Allow 3 weeks: enough for a serious proposal with a draft mockup, not enough to stall. A shorter window favours generic responses.
Which GDPR criteria should I include?
EU hosting, compliant cookie management, a data processing agreement (DPA) and anonymized analytics. These are knockout criteria for a mid-cap in 2026, not mere options.
Why do prices vary so much for the same brief?
Because without a grid, each agency sizes design and dev differently. Gaps reach 2.5x; the weighted grid brings the comparison back to factual ground.
