The verdict in three sentences
A corporate website for a mid-market industrial company (200 to 800 employees) costs between 30,000 and 80,000 EUR (excl. VAT) in 2026, built around a multilingual headless CMS and editorial governance. The timeline is 3 to 5 months depending on the number of languages, the press room, the recruitment module wired to your ATS and the investor data room. RGAA accessibility and GDPR compliance are not optional: they are RFP criteria and a legal risk.
Standard, Premium or Group: what each tier covers
Budget depends mostly on the number of languages, the volume of corporate content and business integrations. Here are the three tiers we quote for an industrial mid-market company.
| Tier | 2026 price (excl. VAT) | Languages | Modules | Timeline |
|---|---|---|---|---|
| Standard | 30,000 - 45,000 EUR | FR + EN | Press, basic HR, CMS | 3 - 3.5 mo |
| Premium | 46,000 - 65,000 EUR | FR/EN/DE | Press, ATS, data room, RGAA AA | 4 mo |
| Group | 66,000 - 80,000 EUR | 3+ languages | Multi-site subsidiaries, intranet, SLA | 4.5 - 5 mo |
| Interactive annual report | + 8,000 - 15,000 EUR | Per site | Data viz, generated PDF | + 3 - 4 wks |
| Maintenance / support | 400 - 900 EUR/mo | - | Security, updates, support | Ongoing |
The headless CMS (e.g. Sanity or Strapi) enables a multi-level approval workflow before publication: essential when corporate communication runs through legal and the executive board.
Cost lines and business integrations
On a corporate website, it is not the pages that drive cost, it is the integrations and governance. Here is the typical split of a Premium project at 55,000 EUR.
| Line | Detail | Budget share |
|---|---|---|
| Design & design system | Digital brand, components | 20 % |
| Headless CMS & architecture | Modeling, editorial workflow | 24 % |
| Multilingual (FR/EN/DE) | i18n, hreflang, editorial ops | 14 % |
| Press & investor room | Releases, secure data room | 12 % |
| Recruitment + ATS | Job connector, applications | 12 % |
| RGAA AA accessibility | Audit, remediation, statement | 10 % |
| QA, SEO, launch | Testing, redirects, training | 8 % |
The ATS connector (Teamtailor, Welcome to the Jungle, SAP SuccessFactors) auto-syncs jobs and pulls in applications: for a company hiring 40 to 80 people a year, that is a direct win for the employer brand.
Mini case study
Catherine, marketing director of a precision-engineering mid-market firm near Lyon (450 employees), launches a FR/EN/DE corporate site at 55,000 EUR. Goal: support German exports and streamline recruitment. Previously, each job posted manually across 4 channels cost ~1.5 h of HR time; with the ATS connector it drops to 10 minutes. Across 60 postings a year, that is ~78 HR hours saved, roughly 2,900 EUR a year, on top of the extra export traffic from the German version.

FAQ
Why a headless CMS rather than WordPress?
For performance, security and multi-level editorial workflow. Headless separates content from presentation, letting you publish to the site, an intranet and an app from the same source. The upfront premium pays back in governance and scalability.
Is RGAA compliance mandatory?
For a private company, the strict legal obligation mainly targets the public sector and large enterprises, but RGAA AA has become an RFP and reputation criterion. Budget 8 to 12 % for audit and remediation.
How much does an extra language cost?
As a 2026 order of magnitude, each additional language adds 10 to 18 % to the budget: translation, editorial ops, hreflang and linguistic QA. A 4th language costs less than the 2nd because the i18n architecture is already in place.
What is a realistic timeline for a Group site?
Between 4.5 and 5 months for a multi-site setup with subsidiaries and intranet. Governance scoping and CMS modeling often take the entire first month.
What support budget should I plan?
From 400 to 900 EUR/month depending on SLA, covering security, backups, minor evolutions and support. A guaranteed 99.9 % uptime with 24/7 monitoring sits at the top of the range.
