The verdict in three sentences
In 2026, an institutional website of 25 to 60 pages for an industrial group is quoted between 20,000 and 45,000 EUR (net), depending on functional scope and the level of editorial governance. A headless CMS such as Sanity adds 6,000 to 12,000 EUR but makes content self-service and multilingual. Plan for 12 to 20 weeks, a day rate of 600-800 EUR and 6 to 12 months of included support.
Standard versus Premium: what each scope covers
The first structuring decision is scope. A Standard site is enough for controlled corporate communication; Premium becomes necessary as soon as there are subsidiaries, investors or a multi-level approval workflow.
| Criterion | Standard | Premium |
|---|---|---|
| Net price 2026 | 20,000-28,000 EUR | 30,000-45,000 EUR |
| Pages | 25-35 | 40-60 |
| CMS | Basic headless | Headless + approval workflow |
| Languages | FR + EN | FR + EN + 1 (RTL possible) |
| Governance | Simple roles | Multi-level + preview |
| Timeline | 12-14 weeks | 16-20 weeks |
| Included support | 6 months | 12 months |
The multi-level approval workflow is often underestimated: it conditions publication compliance for a listed or regulated group. Cost it during scoping, not as a late-stage option.
Typical structure of a 35,000 EUR net quote
A serious institutional quote reads line by line. Here is the split of a Premium project at 35,000 EUR net at a 700 EUR day rate.
| Line item | Share | Net amount |
|---|---|---|
| Scoping, governance, sitemap | 12% | 4,200 EUR |
| Custom corporate UI design | 25% | 8,750 EUR |
| Headless CMS + workflow | 22% | 7,700 EUR |
| Front-end dev & integration | 22% | 7,700 EUR |
| Content, migration, translation | 12% | 4,200 EUR |
| SEO, accessibility, QA | 7% | 2,450 EUR |
Add 20% VAT: 35,000 EUR net becomes 42,000 EUR gross. Also plan 200 to 500 EUR/month of maintenance and managed hosting suited to corporate traffic.
Mini case study
Sylvie, communications director of an industrial group (4 subsidiaries, 620 staff), weighs Standard against Premium. Premium at 34,000 EUR net costs 12,000 EUR more than Standard, but it includes the approval workflow that prevents publishing errors and a multilingual CMS for export subsidiaries. By bringing content updates in-house, she saves about 1.5 agency days/month at 700 EUR, or 12,600 EUR/year. The Premium premium is absorbed in under 12 months, with governance and compliance as a bonus.

FAQ
Why does an institutional site cost more than a showcase site?
Because it funds editorial governance, a multilingual CMS, accessibility and larger content volumes. An institutional site handles compliance and brand stakes a showcase site does not.
Is a headless CMS worth the 6,000-12,000 EUR premium?
Yes as soon as several contributors publish in several languages. It decouples content and display, secures publishing and prepares future channels (app, portal).
How long does an institutional project take in 2026?
Plan 12 to 20 weeks depending on scope and number of approvers. Internal approval and content readiness weigh more than the technology.
What does the 6-to-12-month included support cover?
Fixes, minor adjustments, security and contributor support. Beyond that, a 200-500 EUR/month maintenance contract takes over.
What is the equivalent budget in Berlin?
In 2026, a comparable institutional site is quoted between 25,000 and 55,000 EUR, with day rates and accessibility requirements close to France.
