The verdict in three sentences
A structured requirements brief (RFP) is the only way to get comparable quotes and cut pricing gaps between agencies by 20 to 40 %. It fixes scope, sitemap, technical specs, SEO, GDPR and acceptance testing, which avoids 2 to 3 months of drift mid-project. In 2026, four items concentrate the budget: design, build, CMS/back-end and SEO/QA.
What a redesign RFP must contain
A brief that protects the buyer covers eight blocks: context and quantified goals, functional scope, sitemap and pages, design requirements, technical specifications, SEO and performance, GDPR compliance, and acceptance terms. Without these blocks, each agency prices a different project and comparison becomes impossible.
The classic trap: describing what the site should "look nice" without listing features (forms, client portal, multilingual, connectors). Those functions swing the price from single to triple.
| RFP block | Expected content | Impact on pricing |
|---|---|---|
| Quantified goals | Target leads/month, KPIs | Frames budget priority |
| Functional scope | Precise feature list | High (x1 to x3) |
| Sitemap | Page count, templates | Medium |
| Technical specs | Stack, hosting, connectors | High |
| SEO & performance | Core Web Vitals targets | Medium |
| GDPR | Consent, register | Low but mandatory |
| Acceptance | Acceptance criteria | Reduces disputes |
Typical 2026 budget breakdown
On a mid-range B2B redesign, cost items follow a predictable pattern. Knowing this breakdown helps spot an unbalanced quote (for example oversized design at the expense of SEO).
| Item | Share of budget | Range on a 18,000 EUR project |
|---|---|---|
| Design & UX | 25 - 35 % | 4,500 - 6,300 EUR |
| Front-end build | 30 - 40 % | 5,400 - 7,200 EUR |
| CMS / back-office | 15 - 25 % | 2,700 - 4,500 EUR |
| SEO & QA | 10 - 15 % | 1,800 - 2,700 EUR |
| Project management | 8 - 12 % | 1,440 - 2,160 EUR |
A clear RFP also sets a realistic schedule: 8 to 14 weeks for a 15-to-30-page redesign. Overruns almost always come from a fuzzy scope validated too late.
Mini case study
Sylvie, managing director of a B2B services SME in Nantes, had received three quotes ranging from 11,000 to 34,000 EUR, impossible to compare. She commissions a 14-page RFP (cost 1,800 EUR). The new quotes tighten to 17,000 to 21,000 EUR, a gap of only 20 %. She chooses knowingly, avoids a 6,000 EUR change order for a forgotten client portal, and delivers in 11 weeks without drift. The RFP saved her roughly 8,000 EUR and 6 weeks.

FAQ
How much does writing an RFP cost?
Between 1,200 and 3,500 EUR depending on complexity, sometimes included in a scoping phase. It pays for itself with the first avoided change order (often 3,000 to 8,000 EUR).
Can I reuse a template?
Yes as a starting point, but every project needs its functional scope and technical specs tailored. A raw template without adaptation reintroduces the very ambiguity you want to avoid.
Who should write the RFP: client or agency?
Ideally the client, or a neutral third party. If the shortlisted agency writes it, it naturally steers scope toward its strengths. A paid scoping by a consultant stays more objective.
Should SEO be in the RFP?
Yes, as performance goals (Core Web Vitals > 90) and semantic scope. Adding SEO afterwards costs 30 to 50 % more than building it in from design.
Does an RFP kill flexibility?
No. It sets the reference scope; changes go through priced amendments. That framework is exactly what makes changes controlled rather than imposed.
