The verdict in three sentences
On a marketplace, never let money flow directly from buyer to vendor: collect into a single platform account, then distribute through an internal ledger. Paystack offers split at checkout, but the resilient pattern still keeps a software ledger and materializes payouts weekly. With a 10 to 15 % commission and a clean ledger, you stay solvent, auditable and compliant.
The split architecture: collect then distribute
The robust model has two phases. First the buyer pays 100 % into the marketplace account. Then an internal service writes two ledger lines: the net amount owed to the vendor and the platform commission. Physical money only moves at payout.
Take a ₦10,000 order with a 15 % commission:
| Ledger entry | Account | Debit (₦) | Credit (₦) |
|---|---|---|---|
| Buyer collection | Cash Paystack | 10,000 | — |
| Vendor liability | Vendor payable | — | 8,500 |
| Platform commission | Commission income | — | 1,500 |
| Vendor payout (D+7) | Vendor payable | 8,500 | — |
| Cash out payout | Cash Paystack | — | 8,500 |
After payout, the vendor payable balance returns to zero and the platform keeps the ₦1,500 commission minus disbursement fees.
Commission scale and real fees
The commission rate depends on category and vendor volume. Here is a 2026 order of magnitude for a general marketplace in Lagos:
| Category | Commission | Payout fee (est.) | Net platform on ₦10,000 |
|---|---|---|---|
| Fashion & accessories | 15 % | ~1 % | ~₦1,415 |
| Electronics | 8 % | ~1 % | ~₦715 |
| Local groceries | 12 % | ~1 % | ~₦1,115 |
| Services | 18 % | ~1 % | ~₦1,715 |
| Crafts | 15 % | ~1 % | ~₦1,415 |
Disbursement fees are an estimate; confirm the exact scale in your Paystack contract.
Partial refunds: the real challenge
A customer returns one of three items on a ₦10,000 order. You refund ₦3,400. The ledger must claw ₦2,890 back from the vendor payable (85 %) and ₦510 from commission (15 %), otherwise the platform alone absorbs the loss. If the vendor was already paid, the clawback is deducted from the next payout with a timestamped, traceable line.

Aminata runs a fashion marketplace in Lagos with 40 vendors. In March 2026 she processes 2,800 orders at an average basket of ₦12,500, i.e. ₦35,000,000 of volume. At 15 % commission she earns ₦5,250,000. After ~1 % disbursement fees on the ₦29,750,000 paid out (~₦297,500), her net margin before overhead is about ₦4,952,500. Without an automated ledger she spent 20 h/month reconciling manually; software split brings that under 2 h.
FAQ
Does Paystack offer automatic split at checkout?
Yes, Paystack supports splits, but the resilient pattern still keeps a software ledger so you control refunds and clawbacks. The ledger is the source of truth, not the gateway.
How long should you hold money before payout?
A weekly cycle is the standard: it covers the return window (often 48 to 72 h) and smooths refunds. A weekly payout to 40 vendors costs ~1 % per transfer, a controlled expense.
How do you avoid double-crediting a vendor?
Each payment carries a unique reference and a uniqueness constraint in the database. If the webhook arrives twice, the insert fails and no second credit is written.
What commission rate is realistic?
Between 8 % (electronics, thin margins) and 18 % (services). Above 20 % vendors leave; below 8 % the marketplace struggles to cover its fees.
Should you charge VAT on commission?
Yes, commission is a taxable service. Isolate VAT in a dedicated ledger line to simplify filing.
