The verdict in three sentences
The diaspora wants to pay in USD, GBP or EUR with their card, not guess a local-currency amount. You can display in their currency, collect via international cards and settle in your local currency: two costs stack, card fees (3.5 to 4.5 %) and the FX spread (1 to 3 %). Tuned right, this multi-currency checkout opens a high-spending market without eroding your margin.
The cost of collecting from the diaspora
Each currency and method has its cost and delay. Here is the 2026 order of magnitude for a merchant based in local currency.
| Currency / method | Transaction fee | FX spread | Settlement delay |
|---|---|---|---|
| USD - international card | 3.5 - 4.5 % | 1 - 3 % | T+2 / T+3 |
| GBP - international card | 3.5 - 4.5 % | 1 - 3 % | T+2 / T+3 |
| EUR - Paystack/Flutterwave | ~3.9 % | 1 - 2 % | T+1 / T+3 |
| Local - M-Pesa / MoMo | 1.5 - 3 % | 0 % | T+1 / T+2 |
| USD - wire transfer | Fixed bank fees | negotiated | 2 - 5 days |
Lesson: diaspora cards cost more than local mobile money, but the diaspora basket is often 2 to 4 times larger, which easily absorbs the surcharge.
Global processor vs local aggregator for the diaspora
Two routes to collect internationally: a global processor (worldwide cards) or a local aggregator that accepts intl cards and settles locally. Comparison.
| Criterion | Global processor | Local aggregator |
|---|---|---|
| International cards | Excellent | Good |
| Local-currency settlement | Not direct | Yes |
| Card fee | ~2.9-3.9 % | 3.5 - 4.5 % |
| Local mobile money | No | Yes (M-Pesa/MoMo) |
| Setup | Intl account required | Simple local KYC |
Often the best combination is both: a global processor for cheaper international cards, a local aggregator for mobile money and local settlement. Orchestration routes the customer to the right rail.
Mini case study
Kwame sells crafts from Accra to customers in the UK and US. Average diaspora basket: GBP 80, versus a much smaller local basket. On 40 diaspora orders a month he pays ~4 % card fees plus ~2 % spread = 6 % total. He keeps 94 % of the diaspora revenue net. Without a multi-currency checkout, those 40 orders simply would not have existed.

FAQ
Do I really need to show prices in USD/GBP/EUR?
Yes: a diaspora customer converts poorly in their head and abandons at a local-currency price. Displaying in their currency lifts conversion clearly, even if settlement stays local.
What is the true cost of a diaspora payment?
Expect 3.5 to 4.5 % card fees plus 1 to 3 % FX spread, roughly 5 to 7 % total. The diaspora basket, 2 to 4 times larger, absorbs the surcharge.
Global processor or local aggregator: which to pick?
A global processor is unbeatable on international cards (~2.9-3.9 %); the local aggregator handles local settlement and mobile money. The best option often combines both with routing.
How do I protect my margin from FX?
By locking the display price and monitoring the applied spread: anything above 3 % should be renegotiated or routed to another rail.
