The verdict in three sentences
A B2B website redesign RFP must fix a scope of 25 to 60 pages, clear GDPR requirements, WCAG 2.1 AA accessibility and multilingual support. The indicative 2026 budget for a Berlin group sits between 15,000 and 45,000 EUR, over a timeline of 3 to 5 months. A precise RFP with a weighted scoring grid eliminates 80 % of mid-project surprises.
The mandatory sections of the RFP
An RFP that vendors can actually bid on follows a stable structure. In 2026, neglecting accessibility or GDPR exposes you to costly rework.
| RFP section | Expected content | Criticality |
|---|---|---|
| Context & objectives | Stakes, audience, KPIs | High |
| Functional scope | Pages, modules, workflows | High |
| Technical requirements | Headless CMS, EU hosting | High |
| GDPR & privacy | Consent, register, DPO | High |
| Accessibility | WCAG 2.1 AA, audit | High |
| Multilingual | EN/DE, hreflang handling | Medium |
| SEO & performance | Core Web Vitals, redirects | Medium |
| Maintenance & SLA | Uptime, fix response times | Medium |
A headless CMS (such as Sanity or Strapi) is the norm for a group: it separates content from presentation, eases multilingual work and supports multi-level editorial approval workflows.
Weighted vendor scoring grid
Objective selection rests on a scored grid. Here is a balanced 2026 weighting between price and quality.
| Criterion | Weighting | Score /20 |
|---|---|---|
| Understanding of the brief | 20 % | to assess |
| Quality of references | 20 % | to assess |
| Technical & security approach | 20 % | to assess |
| Accessibility & GDPR | 15 % | to assess |
| Price | 15 % | to assess |
| Timeline & method | 10 % | to assess |
Avoid weighting price above 20 %: on an institutional site, the lowest bid often hides rework. Require 3 comparable references and a live CMS demo before selection.
Mini case study
Claire, communications director of a 400-employee services group in Berlin, launches a tender to redesign a 42-page corporate site in EN/DE. She receives 5 proposals from 18,000 to 38,000 EUR. Applying her weighted grid, the 27,500 EUR offer leads ahead of the 18,000 EUR low bid (weak accessibility score). The 9,500 EUR premium is offset by avoiding a corrective accessibility audit estimated at 6,000 EUR and a 6-week delay. Contracted timeline: 4 months.

FAQ
What budget should I plan for an institutional site in 2026?
Between 15,000 and 45,000 EUR for 25 to 60 pages with headless CMS, multilingual support and compliance. Beyond 60 pages or for a multi-subsidiary group, the budget exceeds 60,000 EUR.
Is WCAG 2.1 AA accessibility mandatory?
For public-mission bodies and large enterprises, the WCAG 2.1 AA obligation applies. An accessibility audit costs 3,000 to 8,000 EUR and must be written into the RFP.
How long does the tender process take?
Count 4 to 8 weeks from publication to selection, then 3 to 5 months of build. A clear RFP shortens the Q&A phase.
Should the RFP mandate the CMS?
Better to express requirements (headless, approval workflow, multilingual) than to mandate a tool, so vendors can propose the best solution.
How do I avoid costly change requests?
By locking functional scope and page volume in the RFP, and including a change-management clause priced at the day rate (550-850 EUR).
