The verdict in three sentences
The cost of a mobile money integration breaks down into three buckets: one-shot development, recurring PSP fees per transaction, and monthly maintenance. In 2026, a single operator costs 300,000 – 600,000 FCFA in dev, versus 800,000 – 1,500,000 FCFA for a multi-operator stack (Wave + Orange Money + MTN). The real question is not the sticker price but the volume threshold at which PSP fees weigh more than development.
Cost items, one-shot vs recurring
Many merchants only look at the development invoice and discover too late that PSP fees eat into margin on every sale. Here is the realistic breakdown for a Senegalese e-commerce site in 2026.
| Cost item | Nature | 2026 range |
|---|---|---|
| 1-operator integration | One-shot | 300,000 – 600,000 FCFA |
| Multi-operator integration | One-shot | 800,000 – 1,500,000 FCFA |
| PSP fee per transaction | Recurring | 1 – 2% of amount |
| Maintenance / API updates | Recurring | 50,000 FCFA / month |
| SSL certificate + hosting | Recurring | 25,000 – 75,000 FCFA / month |
| Accounting reconciliation | Recurring | 30,000 FCFA / month |
One often-forgotten point: operator APIs change version 1 to 2 times per year. Without a maintenance contract, an API break can freeze your collections for several days.
Build in-house or delegate to an agency
The decision hinges on available internal time and the risk of regression on confirmation webhooks.
| Criterion | In-house | Via agency |
|---|---|---|
| Sticker cost | 0 (dev time) | 300,000 – 1,500,000 FCFA |
| Time to launch | 3 – 8 weeks | 1 – 3 weeks |
| Webhook reliability | Variable | e2e tested |
| API maintenance | On you | Included in contract |
| Incident support | None | Defined SLA |

In-house, the cost is hidden: a developer working 4 weeks part-time already represents 400,000 to 800,000 FCFA of real load, with no guarantee of reliable webhooks.
Mini case study
Awa runs a cosmetics shop in Dakar. She sells on average 250 orders per month at an 18,000 FCFA average basket, i.e. 4,500,000 FCFA in revenue. At 1.5% PSP fees, she pays 67,500 FCFA/month. Her multi-operator integration at 1,000,000 FCFA therefore pays for itself, through fees avoided and sales recovered, in under 6 months, because accepting both Wave AND Orange Money lifted her checkout conversion by 12%.
FAQ
Do I pay PSP fees on subscriptions too? Yes, every collected transaction is billed 1 to 2%, including subscription renewals. On 100,000 FCFA collected, expect 1,000 to 2,000 FCFA in fees.
Is Wave cheaper than Orange Money for the merchant? In 2026, pricing varies, but Wave has historically advertised aggressive merchant fees (often around 1%), while Orange Money sits closer to 1.5 – 2%. Always check your current merchant contract.
How much does it cost to add an operator later? Adding a second operator on an already clean base usually costs 200,000 – 400,000 FCFA, versus 300,000 – 600,000 FCFA for the first integration.
Is the 50,000 FCFA/month maintenance negotiable? Yes, it depends on the number of operators and the SLA. A low-volume single-operator site can drop to 30,000 FCFA/month.
