The verdict in three sentences
A training app turns expertise into a scalable product: the course is produced once then sold without limit, with mobile money payment built in. The verifiable certificate raises perceived value and thus conversion, while the subscription creates recurring revenue more stable than one-off sales. The real battle isn't technical but the completion rate, which good quizzes and pacing push up.
The economics of online knowledge
Unlike hourly work, an online course sells with no limit of time or place. The app hosts videos, documents and quizzes, collects via Wave/Orange Money/Stripe, tracks each learner's progress and generates a certificate with a verification code.
Two models coexist: one-off sale (one course = one price) and subscription (access to the whole catalog for a monthly fee). Subscription smooths revenue and raises customer lifetime value.
| Metric | One-off sale | Subscription (2026) |
|---|---|---|
| Average price | 15,000 - 50,000 FCFA / course | 5,000 - 15,000 FCFA / month |
| Revenue | One-time | Recurring (MRR) |
| Completion rate | 10 to 40 % | 20 to 45 % |
| Retention | Low | Medium to high |
| Certificate effect | +conversion | +conversion |
| Marginal cost / sale | ~0 | ~0 |
What drives sales: certificate, quiz, price
A verifiable certificate (unique code checkable online) turns a course into professional proof, which justifies a higher price and improves conversion. Here's a 2026 budget order of magnitude.
| Item | 2026 range (FCFA) | Note |
|---|---|---|
| Training platform (web + mobile) | 2,500,000 - 5,000,000 | Courses, quizzes, certificate |
| Mobile money integration | Included | Wave / OM / Stripe |
| Learner monthly subscription | 5,000 - 15,000 | Catalog access |
| Average course price | 15,000 - 50,000 | By length / level |
| Monthly maintenance | 75,000 - 150,000 | Support + updates |
Since the marginal cost of an extra sale is near zero, every sale beyond break-even is almost pure profit.
Mini case study
Fatou, an accounting trainer, produces 4 courses sold at 25,000 FCFA each. In year one she sells 400 units, i.e. 10,000,000 FCFA. The verifiable certificate lifts her sales-page conversion from 3 % to 4.5 %.
She then launches a 9,000 FCFA/month subscription giving access to the whole catalog. 120 subscribers generate 1,080,000 FCFA MRR, nearly 12,960,000 FCFA/year recurring. The platform, at 3,500,000 FCFA, pays off in under six months, and the marginal cost of each new sale stays near zero.

FAQ
How does the verifiable certificate work?
At course end (often after passing a quiz), the app generates a certificate with a unique code. Anyone — employer, client — can verify its authenticity online, which gives it value.
What completion rate should I target?
In 2026, online courses often run between 10 and 40 % completion. Short modules, regular quizzes and SMS reminders help stay at the top of that range.
Can I collect via mobile money AND card?
Yes. We integrate Wave and Orange Money for the local market and Stripe for international card payments, opening up the diaspora and export.
One-off sale or subscription: which to choose?
Both combine. One-off sales capture occasional buyers; subscription builds more stable recurring revenue (MRR). Many platforms offer both in parallel.
How long to launch?
Expect 6 to 10 weeks for a full platform (courses, quizzes, certificate, payment). You can start with a small catalog and expand later.
