The verdict in three sentences
In 2026, card fraud accounts for 1 to 2.5% of transactions in Africa, and each chargeback costs 15 to 25 EUR in amount + roughly 15 EUR in fees, on top of the risk of a merchant-account block from just 1% of disputes. The right defence is not a single wall but a stack: 3D Secure, anti-fraud rules (velocity, blacklist) and manual review of big orders. The challenge is to block fraudsters without scaring off honest customers with too many false positives.
The real cost of a chargeback
A dispute costs more than the refunded amount. It stacks several losses and a systemic risk.
| Item | 2026 order of magnitude |
|---|---|
| Refunded amount (basket) | 15 to 25 EUR (10,000 to 16,000 FCFA) |
| Dispute handling fee | ~15 EUR (~10,000 FCFA) |
| Lost product / margin | variable |
| Merchant-account block threshold | 1% of transactions disputed |
| Case handling time | 30 to 90 min |
Hitting 1% of disputes can suspend your ability to collect by card — an existential risk, far beyond the amount of any single fraud in isolation.
Three lines of defence compared
| Defence | Fraud reduction | False positives | Customer friction | Best for |
|---|---|---|---|---|
| Mandatory 3D Secure | −60 to −80% | 2 to 5% | Medium | All cards |
| Velocity rules + blacklist | −20 to −40% | 1 to 3% | None (invisible) | Automated attacks |
| Manual review of big orders | −10 to −20% | near zero | Validation delay | High baskets |
3D Secure is the strongest lever, but it introduces 2 to 5% false positives (honest customers blocked). Hence the value of combining it with invisible rules and reserving manual review for orders above a threshold, say 300,000 FCFA.
Mini case study
Fatou runs an online fashion store in Johannesburg, 800 orders a month, 20% by card (160 orders). At a 2% fraud rate she faces about 3 chargebacks a month, at 40 EUR total cost each — 120 EUR (nearly 79,000 FCFA) a month. She enables 3D Secure: fraud drops 70%, cutting disputes to under 1 a month. She adds manual review above 300,000 FCFA, affecting only about ten orders a month. Result: her dispute cost falls below the critical 1% line, and her merchant account is no longer at risk.

At what dispute rate am I in danger?
The critical threshold is around 1% of transactions disputed. Above it, your provider may raise your fees or suspend your merchant account.
Doesn't 3D Secure scare customers away?
It introduces 2 to 5% false positives but cuts fraud by 60 to 80%. The trade-off is very favourable, especially if you avoid imposing needless steps on small trusted baskets.
How do I handle big suspicious orders?
Manual review above a threshold (say 300,000 FCFA) removes 10 to 20% of residual fraud with a near-zero false-positive rate, at the cost of a slight validation delay.
Is mobile money exposed to chargebacks?
Less than card, since there is no classic bank reversal, but abusive refund requests exist. Velocity rules and customer history help filter them.
Does Kolonell integrate these protections?
Yes: we wire 3D Secure, configurable anti-fraud rules and manual-review thresholds into your checkout, with a dispute dashboard.
