The verdict in three sentences
Selling in Naira, Cedi and USD attracts the diaspora, but every conversion adds 1 to 3 % of invisible FX margin that few merchants measure. In 2026 the operator's FX margin (~1.5-2.5 %) dwarfs the real interbank spread (~0.3 %). The winning play: show the local price, collect in local currency, convert in batches rather than per sale.
FX cost table for 2026
2026 order-of-magnitude rates for currency conversion on e-commerce flows.
| FX cost source | 2026 order of magnitude | Who charges it |
|---|---|---|
| Operator / PSP FX margin | 1.5-2.5 % | Payment aggregator |
| Real interbank spread | ~0.3 % | Bank / market |
| Card network conversion | ~1 % | Visa / Mastercard |
| Currency withdrawal fee | 0.5-1 % | Destination bank |
The hidden margin is the gap between the interbank rate (~0.3 %) and the rate the operator applies (up to 2.5 %): as much as 2.2 points of pure loss.
FX loss on USD 5,000/month of diaspora sales
| FX strategy | Effective rate | Monthly loss | Yearly loss |
|---|---|---|---|
| Convert per sale (2.5 %) | 2.5 % | ~USD 125 | ~USD 1,500 |
| Card network conversion (1 %) | 1.0 % | ~USD 50 | ~USD 600 |
| Negotiated monthly batch (0.6 %) | 0.6 % | ~USD 30 | ~USD 360 |
| Collect in local currency | ~0.3 % | ~USD 15 | ~USD 180 |
Moving from convert-per-sale to a monthly batch saves roughly USD 1,140/year — the equivalent of well over FCFA 700,000.

Aminata runs a wax-fashion store selling to the Paris diaspora: USD 5,000/month. Converting per sale at the operator's 2.5 % rate, she loses ~USD 1,500/year. By pricing in the local sale currency, collecting there, then converting once a month in a negotiated batch at 0.6 %, her loss drops to ~USD 360/year — USD 1,140 recovered, roughly a full extra restock every year.
FAQ
Why is the FX margin so hard to see?
It's baked into the exchange rate applied, not billed as a separate line. You only see the amount credited, never the reference interbank rate — hence the invisible gap.
Should I price in local or foreign currency?
Display in the customer's currency to maximize conversion, but collect and hold in local currency where possible to reduce FX exposure.
Is batch conversion risky with a volatile rate?
On pegged pairs (like FCFA/EUR) the risk is near zero. On USD, a weekly batch limits exposure while capturing most of the saving.
How much can I earn as a referral partner?
In e-commerce, 12 % of the sale plus 5 % recurring: introducing 3 stores at FCFA 2,000,000 earns FCFA 720,000 in commissions, before recurring.
Does a multi-currency module slow the checkout?
No, well built it shows the converted price instantly and adds no step. We integrate it with no impact on conversion rate.
