The verdict in three sentences
A marketplace does not scale on its catalog but on its remittance engine: automated split of every order and reliable weekly payout to vendors. On a 10,000 FCFA order at 15% commission, 8,500 FCFA goes to the vendor and 1,500 FCFA to the platform, computed and traced automatically. Two models compete: split-at-capture (immediate) and escrow-then-payout (hold then release), each with its own trade-offs on disputes.
Split-at-capture vs escrow
| Criterion | Split at capture | Escrow then payout |
|---|---|---|
| Split timing | Immediate, at capture | After hold period |
| Dispute handling | Harder (funds gone) | Easier (funds held) |
| Vendor cash flow | Fast | Deferred 3-7 days |
| Tooling | Paystack Split, Flutterwave Subaccounts | Platform hold account |
| Best for | Trusted vendors, small tickets | Big tickets, new vendors |
| Fraud risk | Higher | Lower |
Many platforms combine both: immediate split for established vendors, escrow with a 3-to-7-day hold for new ones or large amounts.
The economics of one order, line by line
Take a typical order and follow every FCFA (2026 order of magnitude, aggregator fee ~2.8%).
| Item | Amount | Share |
|---|---|---|
| Customer order | 10,000 FCFA | 100% |
| Aggregator fee (2.8%) | -280 FCFA | 2.8% |
| Platform commission (15%) | 1,500 FCFA | 15% |
| Vendor remittance | 8,500 FCFA | 85% |
| Vendor payout fee | -100 to -300 FCFA | ~1-3% |
| Vendor net after payout | ~8,200-8,400 FCFA | ~82-84% |
Who absorbs the 280 FCFA aggregator fee? That is a model decision: platform, vendor, or shared. Set it from day one, because over 5,000 orders/month it adds up to 1,400,000 FCFA.

- KYC before any payout: verify vendor identity before the first remittance (legal and anti-fraud requirement).
- Configurable split: commission rate per vendor or category, between 5 and 20%.
- Reserve / hold: keep a share of funds for 3 to 7 days to cover disputes and refunds.
- Weekly batch: group remittances once a week to reduce payout fees.
- Per-vendor reconciliation: a clear statement per vendor (sales, commissions, holds, net paid) to avoid disputes.
Mini case study
Samuel launches an appliance marketplace in Douala. By month 3, 40 active vendors, 1,200 orders, average basket 25,000 FCFA, so 30,000,000 FCFA of volume. At 15% commission, the platform books 4,500,000 FCFA gross. Aggregator fees (2.8%) cost 840,000 FCFA and payout fees ~120,000 FCFA. Net platform margin: ~3,540,000 FCFA. Without automation, Samuel spent 2 days a week computing and making manual transfers with regular errors; with automated split + weekly batch + per-vendor statement, he spends 30 minutes validating and vendor disputes over amounts drop to zero.
FAQ
What is a payment split? It is the automatic division of an order between the platform and the vendor at capture time. On 10,000 FCFA at 15%, the system automatically assigns 1,500 FCFA to the platform and 8,500 FCFA to the vendor, with no manual handling.
Should I pay vendors immediately or hold? For new vendors or large amounts, a 3-to-7-day hold protects against disputes and refunds. For established vendors, an immediate split improves their cash flow and loyalty. Many platforms combine both.
Why pay vendors in a weekly batch? Because each payout costs fees (100 to 300 FCFA). Grouping remittances once a week reduces those fees and simplifies accounting, while staying frequent enough to keep vendors happy.
What commission rate should I pick? Between 5 and 20% depending on the sector and the platform's added value. Kolonell's default is 15%. Service marketplaces often go higher, high-volume goods marketplaces stay lower. The rate must cover your aggregator fees, payout, and margin.
Is KYC required before paying a vendor? Yes, for legal and anti-fraud reasons. Verifying vendor identity (ID, number, payout details) before the first remittance protects the platform and prevents laundering. It is a non-negotiable building block of the payout engine.
