The verdict in three sentences
Full KYC imposed at sign-up scares off nearly half of vendors before they even list a product. No KYC, conversely, opens the door to fraud and makes every payout risky, even illegal. The right 2026 architecture is progressive KYC: minimal friction to register, full verification triggered just before the first disbursement.
Progressive KYC vs full upfront KYC
The dilemma is real: every field added to sign-up costs vendors, every check removed costs in fraud. Progressive resolves the tension by moving the heavy check to the moment money moves.
| Criterion | Progressive KYC | Full upfront KYC |
|---|---|---|
| Onboarding abandonment | ~ 20% | ~ 48% (> 5 fields) |
| Fields at sign-up | 3-4 | 8-12 |
| Document check timing | Before 1st payout | At sign-up |
| Fraud exposure | Low (blocks payout) | Low |
| Time to first listing | Immediate | 24-48 h |
| Active vendors at 30 days | High | Reduced |
What to require, and when
The principle: let vendors create an account and shop with the bare minimum, then require documents when a payout becomes due. This concentrates effort on genuinely active vendors.
| Step | Data requested | 2026 delay / threshold |
|---|---|---|
| Sign-up | Name, email, phone, shop | Immediate |
| First listing | Category, address | Immediate |
| Before 1st payout | National ID or passport + selfie | Verify 24-48 h |
| Business vendor | Business reg. + settlement account | Verify 24-48 h |
| Enhanced check threshold | High monthly volume | Auto-triggered |
| Target vendor fraud rate | — | < 3% |
Vendor fraud runs around 3% without checks; progressive KYC before payout brings it well below, because a fraudster never clears the verified-ID step.

Mini case study
Fatou launches a crafts marketplace in Lagos targeting 200 vendors in the first quarter. With a 10-field form she saw 48% abandonment: of 400 vendor visitors, only 208 finished. Switching to 4 fields at sign-up and deferring ID + selfie to before the first payout, abandonment drops to 20%: 320 accounts created. Of those 320, the ones who actually sell (and trigger a payout) clear document verification in 24-48 h. Result: more active vendors, and no fraud clears the first disbursement.
FAQ
Why does abandonment explode beyond 5 fields? Every extra field adds cognitive friction; past 5, abandonment climbs toward 48%. Cutting to 3-4 fields at sign-up is the most profitable lever.
Which documents before a payout? At minimum an ID (national ID or passport) and a verification selfie; for a business vendor, add the business registration and a settlement account in the matching name.
How long does verification take? Expect 24-48 h in 2026 for document verification, partly automated. The vendor can keep preparing their shop during that time.
Is progressive KYC compliant? Yes, as long as full verification is done before any money movement. No payout should go to an unverified vendor.
How do you handle the 3% fraudsters? They are blocked at the ID + selfie step, before the first disbursement. An enhanced check auto-triggers beyond a certain monthly volume.
