The verdict in three sentences
For an international NGO registered in London with field offices in West Africa, the website serves two very different audiences: UK and European donors who pay by card and expect proof of impact, and local partners browsing on mobile over 3G. A redesign should be judged on one metric, the donation page conversion rate, which can move from 0.5% to 1.5% with a two-step flow and visible trust signals. London agencies typically quote 20,000 to 60,000 GBP, while Kolonell scopes it at 1,830 to 3,050 EUR (Growth) or 3,050 to 5,340 EUR (multilingual Premium).
What makes people give, and what makes them leave
2026 charity sector benchmarks show that a donation page visitor decides in under 30 seconds. Conversion gaps between two equally known charities come down to a handful of measurable elements.
| Donation page element | Estimated conversion impact | Setup cost |
|---|---|---|
| Form in 2 steps maximum | +30 to 50% | Included in redesign |
| Suggested amounts with concrete equivalents (25 GBP = 1 school kit) | +15 to 25% | Copywriting, 1 to 2 days |
| Monthly giving preselected | Recurring gifts up 2 to 3 times | Stripe configuration |
| Gift Aid declaration built into the form | +25% value on eligible UK gifts | Form logic, 1 day |
| Share of funds spent on programmes (e.g. 82%) | +10 to 20% among major donors | Figure already known |
| Mobile money (Wave, Orange Money) for diaspora and local giving | Opens small gifts of 2,000 to 10,000 FCFA | API integration, 3 to 5 days |
| Load time under 3 seconds on 3G | Fewer mobile drop-offs | Image and code optimisation |
The average online gift from a UK or European donor sits between 35 and 60 EUR (2026 order of magnitude), versus 5,000 to 15,000 FCFA for a local or diaspora donor using mobile money. Both audiences deserve their own path, on the same page.
Redesign cost: London agency, freelancer, Kolonell
An NGO with 4 regional offices usually needs pages per programme and per region, a news module, a press area and a second language. Here are 2026 orders of magnitude.
| Option | Budget | Timeline | Languages | Notes |
|---|---|---|---|---|
| UK freelancer (market estimate) | 5,000 to 12,000 GBP | 6 to 10 weeks | EN | Limited capacity for payments and security |
| London charity agency (market estimate) | 20,000 to 60,000 GBP | 3 to 6 months | EN, FR | High quality, budget often out of reach |
| Kolonell Starter | 1,220 to 1,830 EUR (800,000 to 1,200,000 FCFA) | 3 weeks | EN | Simple institutional site, no advanced giving |
| Kolonell Growth | 1,830 to 3,050 EUR (1,200,000 to 2,000,000 FCFA) | 4 to 6 weeks | EN, FR | Donation page, Stripe, news blog, analytics |
| Kolonell Premium | 3,050 to 5,340 EUR (2,000,000 to 3,500,000 FCFA) | 6 to 8 weeks | EN, FR, local language or Arabic | Wave, Orange Money, Stripe, office pages, advanced SEO |
Payment fees are the variable NGO directors tend to underestimate. Indicative 2026 rates: around 1.5% plus 0.20 GBP per UK card gift via Stripe (charity discounts may apply), 1% on Wave, 1 to 2% on Orange Money depending on the merchant contract. On 100,000 GBP of annual card gifts, that is roughly 1,700 GBP in fees.
After launch, maintenance costs 35,000, 75,000 or 120,000 FCFA per month depending on the tier. For campaign and programme page rankings, our monthly SEO packages start at 100,000 FCFA.
Transparency as a conversion lever
Institutional and individual donors check. A credible NGO website in 2026 shows, without extra clicks:
| Proof | Where to place it | Update frequency |
|---|---|---|
| Audited annual accounts and Charity Commission number | Footer and Transparency page | Yearly |
| Spending split (programmes, overheads, fundraising) | Donation page, below the form | Yearly |
| Map of the 4 offices and intervention areas | Home page | Twice a year |
| Impact indicators per programme | Programme pages | Quarterly |
| Partners and funders (logos) | Home page | As agreements are signed |
| Automatic receipt and Gift Aid confirmation | After payment, by email | Instant |
Gift Aid matters a lot: for an eligible UK taxpayer, it adds 25% to the gift at no cost to the donor. A donor who gets a clean receipt in 30 seconds is more likely to give again.

Mini case study
Illustration: Sarah, head of digital at a London-registered education NGO with 4 regional offices in Senegal (Thiès, Kaolack, Ziguinchor, Saint-Louis). The donation page gets 4,000 visitors a month and converts at 0.6%, meaning 24 gifts averaging 40 GBP, about 960 GBP a month.
After a Premium redesign, if conversion reaches 1.5%, she gets 60 gifts, or 2,400 GBP a month. The gain is 1,440 GBP a month, before Gift Aid. First-year investment: 5,340 EUR for the redesign plus 75,000 FCFA monthly maintenance (about 1,370 EUR a year), roughly 6,710 EUR or 5,700 GBP (estimate). The project pays back in about 4 months, before counting diaspora mobile money gifts.
FAQ
Can we accept Wave and Orange Money alongside cards?
Yes, on Premium we integrate Wave and Orange Money merchant APIs next to Stripe. Indicative fees are 1% on Wave and 1 to 2% on Orange Money, versus around 1.5% plus 0.20 GBP for a UK card.
How many languages should an international NGO plan for?
English and French cover 90% of European donors and funders. A third language (Wolof, Arabic or Portuguese) makes sense if your programmes reach those audiences, and is included in Premium up to 5,340 EUR.
Do we need a donor CRM as part of the redesign?
Not necessarily: under 2,000 active donors, an automatic export to a spreadsheet or email tool is enough. Beyond that, a custom donor management app falls in the 2,500,000 to 4,000,000 FCFA range (3,810 to 6,100 EUR).
How long does the redesign take?
Allow 4 to 6 weeks on Growth and 6 to 8 weeks on Premium. Gathering content from the 4 regional offices is usually the critical step, so name one contact per office.
How do we prevent fraudulent card donations?
Stripe Radar filters most stolen card testing, and we add an invisible captcha and a cap per attempt. These measures keep the dispute rate under 0.1% in most cases.
Let's scope your project. A multilingual redesign with a donation page, Gift Aid, Stripe, Wave and Orange Money scopes at 3,050 to 5,340 EUR for a launch in 6 to 8 weeks. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
