The verdict in three sentences
On a marketplace, without trust there is no second purchase — and without repeat purchase, no profitability. The two decisions that build that trust are: verified versus free reviews and escrow versus direct payment. In 2026 in Kampala, verified reviews bring +20 % conversion, escrow cuts disputes by 50 %, and a vendor rating below 4/5 costs 40 % of sales.
Verified reviews and escrow: the two pillars
A free review, which anyone can post, quickly loses credibility: fake reviews, competitor reviews, favour ratings. A verified review, tied to a confirmed purchase on the platform, is worth far more to the buyer. That is why it raises conversion by 20 %: the buyer trusts a signal they know is authentic.
Escrow — holding funds until receipt is confirmed — protects the buyer against defaulting vendors and the vendor against false disputes. It halves the dispute rate because everyone knows the money moves only once the transaction is honoured. It is a particularly powerful trust pillar in a market where cash on delivery remains the norm out of caution.
| Trust mechanism | 2026 effect | Implementation cost |
|---|---|---|
| Verified reviews (confirmed purchase) | +20 % conversion | Moderate |
| Escrow (funds held) | -50 % disputes | High (technical) |
| Product moderation < 24 h | -3 % counterfeits | Recurring (human) |
| Verified vendor badge | +12 % clicks | Low |
| Vendor replies to reviews | +8 % repeat purchase | Low |
| Dispute resolution < 72 h | +15 % retention | Recurring |
Trust is a measurable metric
Trust is not declared, it is measured. A vendor rating, a dispute resolution time, a reported counterfeit rate: all figures to track on a dashboard. The critical threshold is the 4/5 rating — below it, the vendor's sales drop by 40 %, which must trigger support or exclusion.
| Health metric | 2026 target | Alert threshold |
|---|---|---|
| Average vendor rating | ≥ 4.5 / 5 | < 4 / 5 |
| Reported counterfeit rate | < 3 % | > 5 % |
| Dispute resolution time | < 72 h | > 120 h |
| Product moderation | < 24 h | > 48 h |
| Dispute rate / orders | < 4 % | > 8 % |
| Verified reviews / total | > 80 % | < 50 % |

Mini case study
Grace runs a multi-category marketplace in Kampala. At launch she accepts free reviews and direct payment: she suffers 9 % disputes and an average rating of 3.8/5, which drags down conversion. She switches to verified reviews and escrow, and enforces product moderation under 24 h. Within three months, disputes fall to 4 %, the average rating climbs back to 4.4/5 and conversion rises by 20 %. On a monthly GMV of 25,000,000 FCFA, those extra 20 conversion points represent several million FCFA of recovered sales.
FAQ
Verified or free reviews? Verified reviews, tied to a confirmed purchase, bring +20 % conversion because buyers trust them. Free reviews are quickly polluted by fake testimonials and lose all value.
Is escrow worth its technical complexity? Yes. Holding funds until receipt cuts disputes by 50 % and reassures a market used to caution. It is a technical investment but a major trust pillar.
What product moderation time should I target? Under 24 h. Beyond that, counterfeits and prohibited products accumulate, damaging the whole platform's reputation, not just the offending vendor's.
What to do with a vendor below 4/5? A rating under 4/5 drops their sales by 40 % and harms the platform. Trigger targeted support, then suspension if the rating doesn't recover.
