The verdict in three sentences
Redesigning a 120-page foundation website with a donor area and online giving costs between EUR 25,000 and 60,000 excl. VAT in 2026, depending on how deeply it connects to the donor CRM. The most profitable line item is not design but the giving journey, which can lift online donations by 15 to 25%. Plan 4 to 6 months and an accessibility audit (WCAG 2.1 AA, the reference behind EN 301 549 and France's RGAA) from the scoping phase, not at the end.
Three scopes, three budgets
The communications director must first decide on scope. Price gaps come from integrations (CRM, payments, tax receipts) far more than from page count.
| Scope | 2026 budget (excl. VAT) | Content | Online giving | Donor area | Timeline |
|---|---|---|---|---|---|
| Visual and editorial redesign | EUR 25,000 to 35,000 | 120 pages migrated, new identity | Embedded third-party form (iRaiser, Mollie forms) | External link | 4 months |
| Redesign with native giving journey | EUR 35,000 to 48,000 | + campaign and project pages | One-off and monthly giving, automatic tax receipt | Donation history, PDF receipts | 5 months |
| Full platform | EUR 48,000 to 60,000 | + multilingual NL/EN | Gifts, legacies, corporate giving | CRM connection (Salesforce NPSP, HubSpot) | 6 months |
| Accessibility audit | EUR 3,000 to 6,000 | 15 to 20 sample pages | included in audit | included | 2 to 3 weeks |
| Content migration | about EUR 4,000 | 120 pages, media, PDFs | n/a | n/a | 3 to 4 weeks |
| Maintenance and hosting | EUR 300 to 800 a month | updates, backups | payment monitoring | monitoring | ongoing |
Publicly recognised foundations increasingly have to publish an accessibility statement. An audit at EUR 3,000 to 6,000 avoids discovering 40 issues after launch, when each fix costs three times more.
The method that keeps the budget on track
Foundation redesigns almost always slip on content approval by the board and programme teams. The following method limits that risk.
| Step | Duration | Deliverable | Share of budget |
|---|---|---|---|
| Audit of existing site and analytics | 2 weeks | Pages to keep, merge, delete | 5% |
| Donor workshops and journeys | 2 to 3 weeks | Target giving journey, wireframes | 10% |
| Design and web identity | 3 to 4 weeks | Approved mock-ups, accessible components | 20% |
| Development and integrations | 6 to 8 weeks | Site, CRM, payments, tax receipts | 40% |
| Migration and testing | 3 to 4 weeks | 120 pages migrated, 301 redirects | 15% |
| Accessibility audit and fixes | 2 to 3 weeks | Accessibility statement | 10% |
A useful rule: trimming the site from 120 to 70 or 80 pages during the audit is common, because a third of a non-profit site's pages often get zero visits in 12 months. Fewer pages means less migration and less approval work.
Mini case study
Camille, communications director of an education foundation in Amsterdam, raises EUR 420,000 a year online, with an 11% donation form conversion rate. She picks the native giving journey scope at EUR 42,000 excl. VAT, with a EUR 4,500 accessibility audit and EUR 4,000 migration, for a total of EUR 50,500.
After the redesign, the form drops from 9 fields to 5, monthly giving is offered by default and the tax receipt is sent instantly. Assuming a cautious 15% rise in online donations, income grows by EUR 63,000 a year. The redesign pays for itself in about 10 months, before counting the long-term value of monthly donors, as a 2026 order of magnitude.

FAQ
What budget should a foundation plan for a website redesign?
Between EUR 25,000 and 60,000 excl. VAT for a 120-page site, depending on integrations. Most projects land around EUR 35,000 to 45,000 with a native giving journey.
Is an accessibility audit mandatory?
It is for many public-interest bodies under the European Accessibility Act and national rules, and strongly advised for foundations. Expect EUR 3,000 to 6,000 for a 15 to 20 page sample.
Keep a third-party donation tool or build native giving?
A third-party tool is cheap or free but takes donors off your site. A native journey costs EUR 8,000 to 15,000 more and typically lifts online giving by 15 to 25%.
How long does the redesign take?
4 to 6 months on average. Internal approvals often account for 30% of the total timeline.
How do we avoid losing search rankings during migration?
By mapping a 301 redirect for every kept or merged URL. Done well, the traffic dip stays under 5% and lasts a few weeks.
