The verdict in three sentences
A bespoke corporate website in Frankfurt budgets in 2026 between 25,000 and 80,000 EUR for a 20-to-60-page scope, with a headless CMS and custom design. Three-language multilingual adds around +25 %, accessibility conformance +15 %, and sovereign EU hosting costs 150 to 600 EUR/month. Finally, plan for annual maintenance of 6 to 12 % of the build: a corporate site is a living asset, not a frozen deliverable.
The 2026 budget grid
Corporate site cost depends first on page volume and the sophistication of the editorial back-office. Here are the ranges seen on the Frankfurt market for a group or mid-cap.
| Scope | Pages | CMS | 2026 budget (EUR) |
|---|---|---|---|
| Essential corporate | 15-25 | Standard headless | 25,000 - 40,000 |
| Advanced corporate | 25-40 | Headless + workflow | 40,000 - 60,000 |
| Multi-brand group | 40-60 | Headless + multi-site | 60,000 - 80,000 |
| Sovereign EU hosting | - | monthly | 150 - 600 /mo |
| Annual maintenance | - | yearly | 6-12 % of build |
A headless CMS (content decoupled from the front end) lets you serve website, app and press room from a single source. It costs more to integrate but halves the cost of future evolutions.
The hidden costs to anticipate
Three line items inflate the budget and are too often forgotten at scoping. Pricing them up front avoids mid-project overruns.
| Line item | 2026 surcharge | Basis |
|---|---|---|
| 3-language multilingual | +25 % of build | hreflang integration + workflow |
| Accessibility AA | +15 % of build | audit + remediation + testing |
| Editorial governance | 5,000 - 15,000 EUR | roles, approval workflow |
| Professional translation | 0.12 - 0.20 EUR/word | per target language |
| Security audit | 3,000 - 8,000 EUR | pentest + CSP headers |
Structured agency vs freelance collective: the agency charges 15-25 % more but carries contractual liability, accessibility conformance and 3-year continuity. The collective is cheaper but fragments warranty and governance, a real risk for an exposed institutional asset.
Mini case study
Sophie is head of communications at a 900-person industrial group in Frankfurt. She is preparing the budget for a 35-page corporate site, trilingual (DE/EN/FR), fully accessible.
Maths: base build 48,000 EUR, +25 % multilingual = 12,000 EUR, +15 % accessibility = 7,200 EUR, editorial governance 8,000 EUR. Total build 75,200 EUR. Add EU hosting 350 EUR/month (4,200 EUR/year) and maintenance at 8 % = 6,016 EUR/year. First-year full cost: 85,400 EUR. By scoping multilingual to two languages instead of three, she saves 6,000 EUR and gets the file through committee.

FAQ
Why does a corporate site cost 5 to 10 times more than an SME brochure site?
Page volume, multi-stakeholder editorial governance, accessibility conformance and hardened security change the nature of the project. A 60-page site with an approval workflow draws on a cross-functional team over 3-5 months.
Is a headless CMS worth the surcharge?
Yes for a group that publishes often across several channels. It costs 20-30 % more to integrate but halves evolution costs and lets you serve multiple sites from one source.
Is accessibility conformance mandatory?
For bodies meeting certain criteria, yes, with a conformance declaration requirement. Budget +15 % of the build for audit and remediation. It is also an SEO factor and a signal of institutional seriousness.
How much is annual maintenance?
Maintenance runs 6 to 12 % of the build cost per year, i.e. 4,500 to 9,600 EUR for an 80,000 EUR site. It covers security, evolutions, editorial support and version upgrades.
Do I need sovereign EU hosting?
For sensitive data or strong GDPR requirements, it is recommended. Budget 150-600 EUR/month depending on traffic and SLA. EU hosting with CDN and daily backups reassures IT and compliance.
