The verdict in three sentences
Showing the price in the customer's currency lifts conversion and removes FX surprises at debit. In 2026 the diaspora basket is worth 2 to 4 times the local basket, which more than justifies opening USD, GBP and EUR alongside naira and cedi. The real decision: fixed prices per currency (stable margin, simple) versus real-time conversion + FX margin (1 to 3 % on top of payment fees), which becomes mandatory once volatile naira or cedi is involved.
Fixed prices vs real-time conversion
Some pairs are effectively stable and can be pinned; others are volatile. The NGN (Nigeria) and GHS (Ghana) move sharply in 2026, so they need a regular rate refresh or you sell at a loss.
| Criterion | Fixed price per currency | Real-time conversion + FX margin |
|---|---|---|
| FX margin added | 0 % (fixed) | 1 to 3 % |
| FX risk | none on stable pairs | covered by margin |
| Suitable currencies | USD, GBP, EUR | NGN, GHS |
| Update frequency | manual | every session |
| Technical complexity | low | medium |
2026 rule: pin the stable currencies, go real-time for NGN, GHS and any volatile pair.
Providers and diaspora fees
The West African diaspora sends billions of dollars a year. To capture those baskets you need rails that accept international cards and local currencies. Paystack and Flutterwave support NGN, GHS and USD.
| Currency / rail | Typical provider | FX margin | Payment fee | Use |
|---|---|---|---|---|
| USD / card | Flutterwave, Paystack | 1 to 3 % | 3 to 3.8 % | US diaspora |
| GBP / card | Stripe, Flutterwave | 0 to 1 % | 2.9 % + fixed | UK diaspora |
| NGN | Paystack, Flutterwave | real-time | 1.5 to 2 % | Nigeria local |
| GHS | Paystack, Flutterwave | real-time | 1.5 to 2 % | Ghana local |
| Mobile money | MTN MoMo, Airtel | 0 % | 1 to 2 % | Local market |
A full multi-currency module costs between 200,000 and 500,000 FCFA in 2026 depending on how many currencies and providers you wire in.

Mini case study
Ama, a jewellery maker in Accra, sells 90 % locally (average basket GHS 250) and so far refuses foreign cards. Yet she gets 60 requests a month from the diaspora in the UK and USA.
She opens GBP (pinned) and USD (real-time + 2 % FX margin). Average diaspora basket: GHS 750 (3x local). If 40 of the 60 requests convert, that's GHS 30,000/month in new sales. After card fees (~3.5 %) and FX margin, she keeps over GHS 27,000/month, paying back the module in under a month.
FAQ
Can I pin some prices without FX risk? Yes: for stable pairs you set the price once and carry no exchange exposure. Reserve real-time conversion for volatile currencies like naira and cedi.
Why refresh the rate for naira and cedi? NGN and GHS swing hard in 2026. Without a per-session update you risk selling 5 to 10 % below the true rate and eroding your margin.
How much does a multi-currency module cost? Between 200,000 and 500,000 FCFA depending on the number of currencies and providers (Paystack, Flutterwave, Stripe) integrated, excluding transaction fees.
What FX margin should I apply? A margin of 1 to 3 % above the provider fees covers volatility and hidden costs while staying competitive for the diaspora.
Should I show every currency to everyone? No: detect the visitor's country and show the relevant currency by default, while keeping a manual selector for mixed-diaspora cases.
