The verdict in three sentences
The advertised collection rate (1 to 2 %) is only part of the 2026 real cost: fixed fees on small baskets, cash-out, API and disputes all add up. On a 1,000 FCFA transaction, a 75 FCFA fixed fee equals 7.5 % effective, well above the quoted rate. The rule in Abidjan as in Nairobi: the lower the average basket, the more the hidden fees hurt.
Anatomy of hidden fees 2026
Here are the main fee layers seen across MTN MoMo, Moov Money and Wave (2026 order of magnitude).
| Fee type | 2026 range | Who bears it | Frequency |
|---|---|---|---|
| Collection (rate) | 1 to 2 % | Merchant | Every sale |
| Small-basket fixed fee | 50 to 100 FCFA (<1,000 FCFA) | Merchant | Small sales |
| Cash-out / payout | 0.5 to 1 % | Merchant | Withdrawal |
| API subscription | 0 to 25,000 FCFA/month | Merchant | Monthly |
| Manual reconciliation | internal time | Merchant | Weekly |
| Dispute / chargeback | 500 to 2,000 FCFA | Merchant | Dispute |
The classic trap: comparing only the "rate" column and forgetting that fixed fees and cash-out sometimes double the cost on a low-price catalog.
Effective cost by average basket
The same fixed fee weighs very differently by amount. Here is the combined effective cost (1.5 % rate + 75 FCFA fixed fee under 1,000 FCFA) per basket.
| Average basket | Rate fee (1.5 %) | Fixed fee | Total effective cost |
|---|---|---|---|
| 500 FCFA | 8 FCFA | 75 FCFA | 16.6 % |
| 1,000 FCFA | 15 FCFA | 75 FCFA | 9.0 % |
| 2,500 FCFA | 38 FCFA | 0 FCFA | 1.5 % |
| 5,000 FCFA | 75 FCFA | 0 FCFA | 1.5 % |
| 15,000 FCFA | 225 FCFA | 0 FCFA | 1.5 % |
Takeaway: above roughly 2,500 FCFA per basket only the rate matters; below it, fixed fees dominate and can exceed 15 %.
Mini case study
Ibrahim, a restaurant owner in Abidjan, mostly sells 1,500 FCFA dishes and takes in 800 transactions/month, i.e. 1,200,000 FCFA. He thought he paid 1.5 %, but 40 % of his sales fall under 1,000 FCFA with a 75 FCFA fixed fee. His real cost: about 18,000 FCFA in rate + 24,000 FCFA in fixed fees = 42,000 FCFA/month, i.e. 3.5 % effective instead of 1.5 %. By bundling orders (2,000 FCFA combo menu), he pushes 60 % of baskets above the threshold and saves about 15,000 FCFA/month.

FAQ
Which fees are most often overlooked?
The small-basket fixed fee and the cash-out cost. On a low-price catalog they can exceed the advertised rate itself.
Does the mobile money API always cost money?
Not always. Some direct integrations are free, others go through an aggregator charging 0 to 25,000 FCFA/month. Compare by your volume.
How do I reduce the impact of fixed fees?
Raise the average basket (combos, cross-sells) to pass the 1,000 FCFA threshold where fixed fees often disappear.
Are disputes expensive in mobile money?
Less than a bank card, but a dispute can cost 500 to 2,000 FCFA plus your time. Good automatic reconciliation sharply reduces their frequency.
Is it better to integrate directly or via an aggregator?
Directly to minimize fees if your volume is stable; via aggregator for simplicity and multi-operator support if you are starting out.
