The verdict in three sentences
A bilingual EN/FR website for an international NGO costs EUR 5,300 to 12,200 in 2026 (FCFA 3.5 to 8 million when built for a field office in Bamako), over 8 to 12 weeks. Donors now expect online impact reports, a donation module and transparency on funded programmes. The budget usually fits the communication and visibility line of 5 to 7% of projects, provided it is planned in the technical proposal.
What donors ask for, and what it costs
The European Union, AFD, bilateral agencies, foundations and UN bodies have precise visibility rules: logos, funding statements, publication of results. A well-designed site meets them once and for all, instead of patching one page per project.
| Module | Indicative 2026 budget (EUR) | Donor requirement covered |
|---|---|---|
| Bilingual EN/FR design and architecture | 1,200 - 2,400 | Identity, readability, accessibility |
| Programme and project pages (CMS) | 1,400 - 3,000 | Visibility per funder, logos, statements |
| Interactive impact reports (indicators, maps) | 1,100 - 2,700 | Accountability, measured results |
| Online donations (card, SEPA, mobile money) | 800 - 1,800 | Diversified funding |
| Document library (reports, tenders) | 450 - 1,100 | Transparency, archives |
| Low-bandwidth optimization and 12-month hosting | 450 - 1,100 | Access for field partners and beneficiaries |
| Total | 5,300 - 12,200 | 2026 order of magnitude |
Recurring costs stay modest: hosting and maintenance of EUR 75 to 230 per month, and payment fees of 1 to 3% per donation depending on the channel.
A light site for 3G: the thresholds to require
Even for an Amsterdam headquarters, many partners, beneficiaries and journalists in programme countries browse on mobile with unstable connections. A heavy site excludes precisely the people the NGO serves.
| Metric | Typical NGO site | Optimized target |
|---|---|---|
| Average page weight | 3 - 6 MB | < 1 MB |
| Load time on 3G | 8 - 15 s | < 4 s |
| Image format | Uncompressed JPEG | WebP / AVIF, lazy loading |
| Annual report | 20 MB PDF | HTML page + compressed PDF < 3 MB |
| Data cost to the visitor (FCFA 500/GB) | FCFA 1.5 - 3 per page | < FCFA 0.5 per page |
| Offline reading | No | Key pages cached (PWA) |
The under-1 MB rule holds with simple choices: system fonts or a single web font, static maps rather than interactive ones on mobile, videos hosted on an external platform and loaded on click.
Timeline and budget: building it into the funding proposal
Typical timeline: scoping and content collection (2 weeks), design (2), development (3 to 5), content entry and translation (2), testing and training (1). Content collection is the number one cause of delay: appoint one contact per programme. For funding, place the site in the visibility line with a measurable deliverable (site live, X reports published, Y visits), which donors value at evaluation.
Mini case study
Aminata, communications officer of an international NGO, manages 3 funded projects totalling EUR 1,830,000. The 5% visibility line represents EUR 91,500, part of which is already committed to workshops and print materials.

She allocates EUR 8,850 to the website (bilingual, impact reports, card and mobile money donations) and EUR 1,830 to 12 months of hosting and maintenance, EUR 10,680 in total, under 0.6% of the overall project budget. If the donation module collects 150 donations a month at an average of EUR 15, i.e. EUR 2,250 a month in unrestricted funds, the site pays for itself in under 5 months while meeting the visibility obligations of all 3 donors.
FAQ
Can a donor fund the website?
Yes, if it is included in the project's communication and visibility line, usually 5 to 7% of the budget. It must display the statements and logos each funder requires.
Which payment methods for donations?
Cards and SEPA cover European donors, while Orange Money and Wave reach donors in West Africa. Allow 1 to 3% in fees per transaction.
Should we translate into local languages?
For beneficiary-facing pages, a few key pages in a local language or as audio greatly improve access. Budget EUR 230 to 600 for 5 to 10 pages.
How long until the site goes live?
Between 8 and 12 weeks, of which 2 are often lost collecting content. Preparing texts and photos before kickoff cuts the timeline by about 25%.
Who updates the site after delivery?
The communications team, trained on the CMS in half a day. A maintenance plan of EUR 75 to 230 per month covers security, backups and small changes.
