The verdict in three sentences
A collaborative intranet redesign costs 25,000 to 80,000 EUR for 10 to 20 weeks, depending on modules (directory, news, document management, HR workflows). A modern intranet lifts the adoption rate from 20 to 65 % and cuts information search time by 30 %, roughly 1 hour per employee per week returned to useful work. For a 300-person company, that gain alone represents several hundred thousand euros of time per year.
Why old intranets fail
A little-used intranet is not a content problem but an experience one: poor search, no mobile, scattered information. The redesign tackles these causes.
| Symptom (old intranet) | Cause | Redesign answer |
|---|---|---|
| Adoption 15-25 % | dated UX, no mobile | responsive design + app |
| Info impossible to find | weak search | indexed engine + tags |
| Duplicate documents | no structured DMS | document management |
| HR processes by email | no workflow | forms + approval |
| No measurement | no analytics | usage dashboard |
What the redesign budget covers
The core groups directory, news and search. Collaborative modules and HR workflows adjust the price.
| Module | 2026 budget (EUR) | Duration |
|---|---|---|
| Core (directory, news, search) | 12,000-20,000 | 5-6 weeks |
| Document management (DMS) | 6,000-14,000 | 3-4 weeks |
| HR workflows (leave, expenses) | 7,000-16,000 | 3-5 weeks |
| SSO + Microsoft 365 integration | 5,000-11,000 | 2-3 weeks |
| Collaborative team spaces | 5,000-12,000 | 2-4 weeks |
| Mobile app / notifications | 8,000-16,000 | 3-5 weeks |
A typical project combines core + DMS + HR workflows + SSO, around 45,000 EUR for 14 weeks.
What the recovered time is worth
The redesign cost compares against the time employees lose every week searching for information or running a process by email.
| Indicator | Before redesign | After redesign |
|---|---|---|
| Adoption rate | 20 % | 65 % |
| Information search time | ~3.5 h/week | ~2.5 h/week |
| Leave approval delay | 3-5 days | <1 day |
| Obsolete documents circulating | high | controlled (DMS) |
| Internal satisfaction (eNPS) | low | +15 to +25 pts |

Nathalie is HR director of a 320-employee services company in Nantes. Her legacy SharePoint intranet is used by 22 % of teams; leave and expense requests go by email. She commissions a 48,000 EUR redesign with DMS, HR workflows and Microsoft 365 SSO, delivered in 15 weeks. Adoption reaches 64 % within a quarter and each employee regains about 1 h/week. Across 320 people at an average loaded cost of 28 EUR/h, those hours represent about 470,000 EUR/year of redeployed time: the redesign pays back in a few weeks of use, before counting fewer HR process errors.
FAQ
How much does an intranet redesign cost in 2026?
Between 25,000 and 80,000 EUR depending on modules; a directory + news + search core starts around 25,000 EUR, a full platform with HR workflows and mobile approaches 80,000 EUR.
Should we start over or modernize the existing one?
It depends on the debt: a heavily customized SharePoint can be modernized, but beyond a certain age a redesign on a modern core is often cheaper to maintain.
How do you guarantee adoption after launch?
Mobile, strong search and Microsoft 365 integration are decisive; a change-management plan pushes adoption beyond 60 % within a quarter.
Does the intranet integrate with Microsoft 365 or Google Workspace?
Yes, SSO and directory/file connections are built for 5,000 to 11,000 EUR and avoid double account management.
What annual maintenance budget should I plan?
Expect 12 to 18 % of development cost per year for evolutions, security and support, plus hosting.
