The verdict in three sentences
The diaspora card is a valuable but risky channel: its chargeback rate runs around 1.2%, versus 0.3-0.5% locally. The real danger is not the refunded amount but the 0.9% network threshold that triggers monitoring programs (and fines). Your best defense is documentary: 3DS, proof of delivery and KYC kept systematically.
Anatomy of a dispute's cost
A chargeback never costs only the contested amount. 2026 orders of magnitude.
| Item | 2026 order of magnitude |
|---|---|
| Diaspora card chargeback rate | ~ 1.2% |
| Local chargeback rate | 0.3 - 0.5% |
| Fixed fee per dispute | 5,000 - 15,000 FCFA |
| Customer dispute window | up to 120 days |
| Time to respond (representment) | 7 - 20 days |
| Network alert threshold | 0.9% |
| Win rate with a full file | 40 - 60% |
Above the threshold, you risk fee surcharges, a financial reserve, even termination of the merchant account.
Defense and prevention: the evidence table
Winning a dispute comes down to the quality of the file sent within 7-20 days. Prevention is better: every missing proof is a lost dispute.
| Dispute reason | Decisive evidence | Prevention |
|---|---|---|
| Unauthorized transaction | Successful 3DS authentication | Force 3DS on diaspora |
| Item not received | Tracking + delivery signature | Systematic tracking number |
| Item not as described | Photos + customer messages | Description + fast support |
| Unwanted subscription | Mandate + reminder emails | Double opt-in, D-3 reminder |
| Friendly fraud | KYC + account history | Cap first order |
3D Secure shifts fraud liability to the issuing bank: it is lever number one.
Mini case study
Ibrahim sells traditional outfits in Abidjan to a diaspora clientele (2,500,000 FCFA/month, 200 orders). At 1.2%, he faces about 2-3 disputes/month. By enabling 3DS and always attaching tracking, he drops his rate to 0.4% and wins 55% of remaining disputes — saving fixed fees and, above all, staying below the 0.9% threshold.

FAQ
Why does the diaspora generate more chargebacks?
Time-zone gaps, foreign cards poorly recognized by anti-fraud systems, international delivery delays and sometimes "friendly fraud" (a relative used the card). The ~1.2% rate in 2026 follows.
How long does a customer have to dispute?
The window often reaches 120 days after the transaction depending on the network, so keep evidence for several months.
Does 3DS prevent all chargebacks?
No, but it shifts liability for "unauthorized" fraud to the issuer. It does not cover "item not received" disputes.
What happens if I exceed 0.9%?
You may enter a network monitoring program, with monthly fees, a financial reserve and the threat of losing card acceptance.
Should I push mobile money for the diaspora?
Where possible, yes: mobile money has no network chargeback. But much of the diaspora only has cards, hence the value of solid 3DS.
