The verdict in three sentences
To cover Europe and francophone Africa, your agency must master two worlds: Stripe/cards on the European side and Wave/Orange Money on the African side, with a site built for low-data and multilingual use. A purely local agency (European or African) always leaves a blind spot paid for in delays and rebuilds. The right criterion is not the lowest price but proven bi-continental capability backed by references.
A criteria grid to decide
Assess each agency on objective criteria, not sales feeling.
| Criterion | What to require | Weight |
|---|---|---|
| Bi-continental references | Delivered Europe + Africa projects | High |
| Modern stack | Next.js/React, headless, API | High |
| Payments | Native Stripe + Wave + Orange Money | High |
| Security & GDPR | Compliance, hosting, encryption | High |
| Multilingual & i18n | FR/EN (even Arabic RTL) | Medium |
| Low-data performance | 3G-optimized, WebP, edge/CDN | Medium |
| Code ownership | IP assignment, Git repo on your side | High |
An agency ticking fewer than 5 of 7 exposes you to costly patches in phase 2.
Budget ranges by project type
2026 orders of magnitude help calibrate a tender and flag abnormal quotes.
| Project type | 2026 indicative budget | Timeline |
|---|---|---|
| Multilingual showcase site | 4,500-12,000 EUR | 3-6 weeks |
| Site + blog + advanced SEO | 12,000-25,000 EUR | 6-10 weeks |
| Wave/Stripe e-commerce | 15,000-45,000 EUR | 8-14 weeks |
| Custom business web app | 40,000-120,000 EUR | 3-6 months |
| Platform / marketplace | 80,000-250,000 EUR | 5-10 months |
A quote 40 % below the low range often hides a truncated scope or programmed technical debt.

Mini case study
Karim, marketing director of a cosmetics brand in Lyon, wants to sell in France and Senegal. A French agency offers a Stripe e-commerce at 38,000 EUR — without Wave, which nonetheless accounts for 60 % of payments in Senegal. He picks a bi-continental agency at 32,000 EUR with native Stripe + Wave + Orange Money. Result: simultaneous launch on both markets, +40 % conversion on the Senegalese side thanks to mobile payment, and 6,000 EUR saved.
FAQ
Why not pick the cheapest agency? Because an abnormally low quote hides a truncated scope, a fragile stack or technical debt. A 3-month delay on a 60,000 EUR project can cost 15,000 EUR in lost revenue and rework.
Is mobile payment really essential? In West Africa, yes: Wave and Orange Money capture most transactions. An e-commerce without them loses most of its local conversion, whatever the design quality.
How to verify bi-continental capability? Ask for quantified references on both markets, live demos and payment stack detail. A credible agency shows Europe AND Africa projects already in production.
What budget for a dual-market e-commerce? Count on 15,000 to 45,000 EUR in 2026 depending on catalog, integrations and customization. The added cost of Wave/Orange Money is marginal against the conversion gain.
Who keeps code ownership? Require an IP assignment clause and a Git repo on your organization. Without it, you stay locked to the agency for every future change.
