The verdict in three sentences
A multi-subsidiary corporate website for an industrial group in 2026 lands between 50,000 and 100,000 USD for the corporate platform plus three subsidiary sites. The delivered design system (7,000-17,000 USD) and multi-level editorial governance are the two line items CIOs most often underestimate. Plan for 4 to 6 months and ongoing maintenance of 1,000 to 2,200 USD/month to sustain SLA and security over time.
The line-by-line breakdown
A corporate project budget is never just "the price of the site." It is a platform, a shared technical foundation and a governance framework. Here are 2026 orders of magnitude for a mid-size group (corporate + 3 subsidiaries).
| Line item | 2026 range (USD) | Comment |
|---|---|---|
| Discovery & architecture | 6,000 - 12,000 | Workshops, sitemap, specs |
| Delivered design system | 7,000 - 17,000 | Tokens, components, Figma docs |
| Corporate platform | 22,000 - 38,000 | Headless CMS, templates, integrations |
| 3 subsidiary sites | 17,000 - 33,000 | Shared base, own content |
| Editorial governance | 4,500 - 9,000 | Multi-level approval workflow |
| Accessibility (WCAG audit) | 3,500 - 7,000 | Audit + fixes |
| QA & go-live | 3,500 - 7,000 | Testing, migration, training |
| Project total | 50,000 - 100,000 | Excluding recurring |
The design system is the structural investment: delivered once, it cuts the marginal cost of every future subsidiary by 30 to 50%. A group planning to open 2 subsidiaries a year amortizes this line in under 18 months.
Recurring costs not to forget
Operating TCO weighs heavily over 3 years. A high-availability corporate site demands more than 15 USD/month shared hosting.
| Recurring item | 2026 range | Basis |
|---|---|---|
| High-availability hosting | 170 - 450 USD/month | 99.9% SLA |
| Application maintenance | 1,000 - 2,200 USD/month | Fixes + enhancements |
| Monitoring & security | 55 - 220 USD/month | WAF, 24/7 alerts |
| Certificate & compliance | 170 - 450 USD/year | EV / audit |
| Backups & DR | 35 - 140 USD/month | Defined RPO/RTO |
Over 3 years these recurring costs often add 45,000 to 70,000 USD: build them into the RFP from day one to avoid budget surprises in year 2.
The criteria that win an RFP
A well-scored RFP in 2026 rewards: agile methodology (sprints, weekly reviews), proof of WCAG 2.1 AA accessibility, reversibility (source code delivered, no lock-in), security (regional hosting, CSP headers) and a 3-year maintenance plan with figures. Vendors who present a documented design system and clear editorial governance consistently stand out.
Mini case study
Laurent, CIO of a 600-employee industrial group in New York, is scoping an RFP for a corporate platform plus 3 metallurgy subsidiaries. Selected project budget: 76,000 USD, of which 14,000 USD for the design system. Recurring: hosting 320 USD/month + maintenance 1,600 USD/month = 23,040 USD/year.

Amortization math: the design system lets him open a 4th subsidiary for 9,000 USD instead of 17,000 (saving 8,000 USD). With 2 openings planned over 3 years, cumulative savings reach 16,000 USD, more than the initial design system cost. Total 3-year TCO comes to ~145,000 USD, a coherent order of magnitude for a group this size.
FAQ
How much does the corporate platform alone really cost?
Between 22,000 and 38,000 USD in 2026, excluding subsidiaries and design system. That covers the headless CMS, templates and base integrations.
Is the design system essential?
For a multi-subsidiary group, yes. Delivered at 7,000-17,000 USD, it cuts the cost of each new site by 30 to 50% and guarantees brand consistency.
What timeline for a multi-site project?
Expect 4 to 6 months from discovery to go-live, depending on the number of subsidiaries and the complexity of ERP integrations.
What SLA should a corporate site require?
A 99.9% uptime SLA is the 2026 standard, meaning under 8.8 hours of downtime per year, with 24/7 monitoring and regional hosting.
Should maintenance be budgeted at the RFP stage?
Yes. Maintenance of 1,000 to 2,200 USD/month equals 36,000 to 79,000 USD over 3 years: omitting it completely distorts the bid comparison.
