The verdict in three sentences
A successful B2B redesign RFP rests on two pillars: measurable objectives (KPIs) and a precise scope (features, SEO, RGAA accessibility, GDPR, support). Without both, the quotes you receive are incomparable and vary threefold. For a standard project, the 2026 range is 20,000 to 70,000 EUR (excl. VAT) over 3 to 5 months, and a weighted scoring grid keeps you from choosing on gut feel.
The mandatory RFP sections
A vague RFP produces vague quotes. Here are the sections you must never omit and their impact on offer comparability.
| Section | What it contains | Why it matters |
|---|---|---|
| Context & objectives | Business stakes, target | Aligns vendors |
| Measurable KPIs | Conversion, traffic, LCP | Makes success verifiable |
| Functional scope | Pages, modules, integrations | Prevents out-of-scope |
| SEO & migration | 301 redirects, schema | Preserves rankings |
| RGAA accessibility | Target AA level | Reduces legal risk |
| GDPR & hosting | Consent, EU | CNIL compliance |
| Support & warranty | Maintenance, SLA | Frames post-launch |
The KPI section is the one 70 % of RFPs forget: without a quantified goal (e.g. +40 % leads, LCP under 2.5 s), you can never measure the redesign's ROI.
Quote scoring grid
Once quotes arrive, score them on a weighted grid rather than by intuition. Here is a model we recommend to our enterprise clients.
| Criterion | Weight | What you assess |
|---|---|---|
| Understanding of need | 20 % | Reframing, relevant questions |
| Design quality / references | 20 % | Portfolio, sector fit |
| Technical approach & perf | 20 % | Stack, Core Web Vitals, security |
| SEO & accessibility | 15 % | 301 plan, RGAA, method |
| Price & lot breakdown | 15 % | Transparency, phasing |
| Timeline & dedicated team | 10 % | Realistic plan, contacts |
A vendor with the lowest price but weak on SEO and performance will cost you more in lost traffic. Weight the technical side as much as the budget.
Mini case study
Sophie, digital lead of a B2B group in Rennes, receives 5 quotes ranging from 24,000 to 68,000 EUR for the same redesign. Without a grid, she would have picked the cheapest. Applying the weighted grid, the 41,000 EUR quote comes out on top (85/100) thanks to a solid SEO plan and a dedicated team, versus 62/100 for the cheapest (weak on RGAA and redirects). The 17,000 EUR premium pays back in year one: the higher-scored vendor preserves 100 % of organic traffic, whereas the cheapest would have lost ~30 % of leads, far more than the price gap.

FAQ
How long should a B2B redesign RFP be?
Between 8 and 20 pages depending on scope. Too short and quotes diverge; too long and you deter good vendors. What matters is precision on KPIs, scope and technical constraints.
Should I state a budget in the RFP?
Yes, a range (e.g. 30,000-50,000 EUR) is recommended: it filters out-of-target offers and saves everyone time. Hiding the budget produces unusable quotes.
How many vendors should I consult?
Three to five at most. Beyond that, analysis becomes unmanageable and you lack time to seriously evaluate each offer. Prioritize a quality short-list.
How long does a redesign RFP take?
Budget 4 to 8 weeks between sending the RFP and selection: drafting, distribution, Q&A, pitches and scoring. Anticipate this before the project itself (3 to 5 months).
Should I include support in the RFP?
Yes, application maintenance and the SLA must be included from the start. An attractive build price followed by an overpriced support contract is a classic trap: ask for the full cost over 3 years.
