The verdict in three sentences
A corporate foundation website with online donations, calls for projects and an impact report costs between EUR 15,000 and 35,000 excl. VAT in Paris in 2026, depending on the depth of the donation module and the interactivity of the report. The core value is twofold: automatic tax receipts (individual donors in France get a 66% income tax reduction) and proof of impact project by project, which protects the founding company's reputation. Before pricing, check who can give: a French corporate foundation (fondation d'entreprise) cannot appeal to the general public, it collects mainly from employees, officers, shareholders and group companies.
The four building blocks and their cost
The executive director of a typical Paris corporate foundation (a group with 4,800 employees, 40 funded projects, a multi-year budget of EUR 2.5M) has three audiences: nonprofits applying for funding, employees who donate or volunteer their skills, and stakeholders (press, CSR department, board members) who want evidence. The website must serve all three without becoming an institutional brochure.
| Building block | Content | 2026 range (EUR excl. VAT) |
|---|---|---|
| Editorial site | Mission, governance, focus areas, news, 10 to 15 pages | 5,000 to 9,000 |
| Project pages | 40 projects, filters by focus area, region, year, amount committed | 2,500 to 5,500 |
| Donation module | One-off or monthly gifts, card, SEPA, donor account | 3,000 to 7,000 |
| Automatic tax receipts | Numbered PDF generation, email delivery, accounting export | 1,500 to 3,500 |
| Online calls for projects | Application upload, attachments, scoring grid, jury | 3,000 to 8,000 |
| Interactive impact report | Project map, indicators, animated figures, PDF export | 2,500 to 7,000 |
A foundation starting with the editorial site, project pages and a simple donation module lands around EUR 15,000 excl. VAT. A calls-for-projects platform with online jury and an interactive impact report lead to EUR 30,000 to 35,000 excl. VAT. Accessibility (contrast, keyboard navigation, text alternatives) should be built in from design: it is 5 to 10% of the budget if planned, double if fixed afterwards.
Online donations: provider, fees and tax
The payment provider choice determines fees, donor experience and admin workload. There are three families: donation platforms specialised in nonprofits, general payment providers integrated into the site, and free solutions funded by a tip requested from the donor. For a corporate foundation, image matters: a tip requested at checkout may be poorly received by employees.
| Payment option | Typical 2026 fees | Tax receipt | Watch point |
|---|---|---|---|
| Dedicated donation platform | 0.8 to 1.5% plus EUR 0.25 | Automatic | Subscription EUR 0 to 100 a month |
| General payment provider | 1.5% plus EUR 0.25 (European cards) | To be built | More design flexibility |
| Monthly SEPA direct debit | EUR 0.35 to 0.80 per debit | Annual summary | Better donor retention |
| Free solution with tip | 0% for the foundation | Automatic | Tip requested from donor |
| Direct bank transfer | EUR 0 | Manual | Manual entry and reconciliation |
On tax, an individual giving EUR 150 gets a EUR 99 tax reduction (66%, up to 20% of taxable income): their real cost is EUR 51. Corporate donors get a 60% reduction (40% above EUR 2M of gifts), capped at EUR 20,000 or 0.5% of revenue. Showing this calculation on the donation page, with a simulator, noticeably raises the average gift. The receipt must follow the official Cerfa template and be numbered without gaps: this is the feature to test first.
Allow 8 to 12 weeks for the project, calls for projects included, with 2 weeks of acceptance testing with the finance department for receipts.
Mini case study
Camille, executive director of a services group's foundation in Paris (4,800 employees), currently collects via paper forms and bank transfers: 3% of employees give, EUR 90 on average, i.e. EUR 12,960 a year. The team spends about 10 minutes on each manually issued tax receipt.

With a website at EUR 28,000 excl. VAT (one-off and monthly gifts, automatic receipts, calls for projects, impact report), the target is 9% of employees giving at an average of EUR 110, driven by the tax simulator and monthly giving: 432 donors, i.e. EUR 47,520 raised. Payment fees at 1.2% come to about EUR 570. Admin time saved on receipts reaches 72 hours a year. Over two annual campaigns, the additional funds raised (about EUR 34,500 a year) exceed the website cost before the end of year one, with EUR 3,000 of annual maintenance.
