The verdict in three sentences
A marketplace's trust is won at the moment of dispute, not at purchase. An escrow model (funds held until delivery confirmed) plus a clear 48h resolution SLA keep both sides on the platform. In Nairobi, keeping a dispute rate below 4% is the true health metric of a marketplace.
The dispute cycle
The buyer's money must not reach the seller before delivery is confirmed. This hold window turns the platform into a trusted third party and makes every dispute arbitrable on evidence.
| Step | 2026 rule | Delay |
|---|---|---|
| Buyer payment | Funds held in escrow | Immediate |
| Delivery confirmation | Buyer validates or 72h auto | 0-72h |
| Dispute opened | Evidence required (photo, tracking) | Up to D+3 |
| Platform arbitration | Decision on evidence | 48h |
| Release or refund | Per decision | Immediate |
| Escalation | Manual mediation | 5 days |
In Douala, the same mechanism relies on a mobile-money hold and evidence-based arbitration.
Refund vs release rules
| Situation | Default decision | Share refunded |
|---|---|---|
| Proven non-delivery | Buyer refund | 100% |
| Non-conforming product (photos) | Partial refund | 50-100% |
| Dispute with no buyer evidence | Seller release | 0% |
| Late delivery, no damage | Seller release | 0% |
| Repeat-offender seller (3 disputes) | Suspension + refund | 100% |
| Shipping-damaged parcel | Insurance split | 50% |

Mini case study
In Nairobi, Wanjiru's marketplace handles 800 orders/month. At a 4% dispute rate, that's 32 disputes. Without escrow, she refunded out of pocket and lost sellers. With the hold-until-delivery model, 24 disputes resolve for the seller (proven delivery) and 8 in buyer refunds. Refund provision: 2% of a 12,000,000 KES GMV, or 240,000 KES/month, easily covered by commission.
FAQ
Do you really need to hold funds before delivery? Yes. Escrow is the only mechanism that makes arbitration credible: without it, a pre-paid seller has no incentive to resolve the dispute.
Which dispute rate is alarming? Above 4% of orders, hunt the root cause: fraudulent sellers, misleading descriptions or a failing carrier.
How long to settle a dispute? Aim for 48h on evidence. Beyond that, frustration pushes buyers and sellers to deal off-platform.
What about a repeat-offender seller? Automatic suspension on the 3rd valid dispute, with full refunds to affected buyers. Better to lose one bad seller than ten buyers.
Does this kind of project earn a referral commission? Yes: a marketplace project referred to Kolonell pays the referrer 10%.
