The verdict in three sentences
Split payments divide each collection between platform and vendor: badly calibrated, they wreck vendor cash flow or erode your margin. On a 10,000 basket at 15 % commission, the platform keeps 1,500 and pays out 8,500 net, less 0.5 to 1 % payout fees. The real decision: instant split (vendor paid immediately) or weekly deferred (better handling of refunds and disputes).
Money flow by commission rate
For the same 10,000 basket, here is the breakdown at three common commission rates on a 2026 marketplace (payout fees estimated at 0.8 %).
| Line item | 10 % commission | 15 % commission | 20 % commission |
|---|---|---|---|
| Buyer basket | 10,000 | 10,000 | 10,000 |
| Platform commission | 1,000 | 1,500 | 2,000 |
| Collection fee (1 %) | 100 | 100 | 100 |
| Payout fee (0.8 %) | 72 | 68 | 64 |
| Net paid to vendor | 8,900 | 8,500 | 8,000 |
| Platform net margin | 828 | 1,332 | 1,836 |
Beyond the headline rate, it's the collection fees (borne by platform or vendor?) and VAT on commission that determine real margin. Clarify these rules in your vendor terms from day one.
Instant vs deferred split: which to pick?
Instant split reassures vendors (paid on sale) but complicates refunds: if the buyer cancels after payout, you must claw funds back. Deferred split (weekly payout) gives a window to handle disputes and returns before paying.
| Criterion | Instant split | Deferred split (weekly) |
|---|---|---|
| Vendor satisfaction | High | Medium |
| Refund handling | Hard (clawback) | Simple (withhold before payout) |
| Platform cash risk | Low | Moderate (funds held) |
| Reconciliation load | High | Low (1 cycle/week) |
| Recommended for | Trusted vendors | Consumer marketplace |
For a consumer marketplace with frequent returns, weekly deferred is often safest: it aligns payout with the end of the return window.

Mini case study
Awa launches a fashion marketplace in Lagos with 15 % commission and weekly deferred split. In one week, 120 orders for a GMV of 1,800,000. Gross commission: 270,000. Of those sales, 6 orders are refunded (90,000) before payout, withheld with no clawback. Net paid to vendors: 1,800,000 − 270,000 − 90,000 = 1,440,000, settled in one bulk payout at 0.8 % (11,520 in fees). Thanks to deferral, no refund required recovering already-paid funds.
FAQ
Who pays the collection fees in a split? It's a model choice: either the platform absorbs them (thinner margin) or they pass to the vendor (lower net). What matters is spelling it out in the terms to avoid disputes.
How do you handle a refund after an instant split? You need a clawback mechanism: withhold the amount from the vendor's future sales, or request a reversal. This is instant split's main weakness, hence the appeal of deferral.
Is commission subject to VAT? Yes, platform commission is a service supply that is generally taxable. Build VAT on commission into your net-margin calculation from the design stage.
What commission rate should you pick? Between 10 and 20 % by category: 10 to 12 % for low-margin products, 15 to 20 % for services or handmade goods. Test and adjust based on vendor retention.
Does split work with local wallets like Flutterwave? Yes, you collect the full basket then compute the vendor net for the weekly payout. Split need not be provider-native: it's handled platform-side at reconciliation.
