The verdict in three sentences
The sticker rate (often 1.2-1.5%) is only the visible part: your real cost also includes payout fees, FX markup, failed payments and the human time spent reconciling. On 5,000,000 FCFA of monthly volume, the effective rate frequently climbs to 4-6%, or 200,000-300,000 FCFA per month. Measuring your true TCO lets you negotiate, pick the right provider and save several hundred thousand FCFA per year.
The six cost layers nobody calculates
The cost of accepting payments breaks down into layers. Most merchants only look at the first one, while the next five often weigh more.
| Cost layer | 2026 range (order of magnitude) | Often forgotten? |
|---|---|---|
| Advertised transaction fee | 1.2% to 3.5% | No |
| Withdrawal / payout fee | 0.5% to 1.5% or flat 200-500 FCFA | Yes |
| FX markup on EUR/USD sales | 2% to 4% | Yes |
| Cost of failed payments (retry, lost cart) | 0.3% to 1% of volume | Yes |
| Manual reconciliation time | 3 to 10 h/month | Yes |
| Fixed monthly / subscription fee | 0 to 25,000 FCFA | Sometimes |
A nicely negotiated "1.5%" rate can hide an effective rate of 5% once FX and payouts are included.
TCO simulated by monthly volume
Here is an estimate of total monthly cost by volume, for a store collecting via mobile money with 15% international card sales. Providers such as Paystack (1.5%), Flutterwave or M-Pesa apply similar layered structures.
| Monthly volume | Transaction fee (1.5%) | Payouts + FX | Failures + reconciliation | Estimated TCO | Effective rate |
|---|---|---|---|---|---|
| 1,000,000 FCFA | 15,000 FCFA | 12,000 FCFA | 8,000 FCFA | 35,000 FCFA | 3.5% |
| 3,000,000 FCFA | 45,000 FCFA | 33,000 FCFA | 22,000 FCFA | 100,000 FCFA | 3.3% |
| 5,000,000 FCFA | 75,000 FCFA | 55,000 FCFA | 40,000 FCFA | 170,000 FCFA | 3.4% |
| 10,000,000 FCFA | 150,000 FCFA | 100,000 FCFA | 70,000 FCFA | 320,000 FCFA | 3.2% |
The higher the volume, the more rate negotiation and reconciliation automation pay off: one percentage point saved on 10,000,000 FCFA is 100,000 FCFA per month.

Awa runs a cosmetics store in Dakar. She collects 4,000,000 FCFA/month, 10% by card for the diaspora. She thought she paid 1.5%, i.e. 60,000 FCFA. In reality: 60,000 FCFA transaction + 24,000 FCFA payouts + 12,000 FCFA FX markup on cards + roughly 15,000 FCFA of carts lost to failures = 111,000 FCFA/month, an effective rate of 2.8%. By switching to a provider with free payouts and adding automatic retries on failed payments, she drops to around 80,000 FCFA/month and saves ~370,000 FCFA/year.
FAQ
Why is the effective rate always higher than the sticker rate?
Because the sticker rate only covers transaction authorization. Withdrawals to your account, currency conversion and failed payments typically add 1 to 3 percentage points to the real cost.
How much does a failed payment cost?
A failure carries no direct fee, but you lose the sale if the customer gives up. With a 5-12% failure rate on mobile money and effective retries, you recover 20-40% of those carts, often worth 0.3 to 1% of volume.
Is FX markup worth optimizing?
If you sell to the diaspora in EUR or USD, a 3% FX markup on 500,000 FCFA of international sales is 15,000 FCFA/month. Choosing a lower-markup provider or billing in local currency can halve that cost.
At what volume should you negotiate your rate?
From 3,000,000 to 5,000,000 FCFA of monthly volume, most aggregators will discuss a tiered rate. Above 10,000,000 FCFA, a custom rate and free payouts are realistic.
