Marketplace split payments with Paystack subaccounts in 2026

The verdict in three sentences

The split must be computed at order time, not at payout, otherwise you lose traceability the moment a dispute or refund appears. In 2026 the platform commission sits between 10 % and 15 %, leaving 85 % to 90 % to the vendor. Two architectures compete: split at capture (the provider divides the money live) or internal ledger + deferred payout (you capture everything, then pay out).

Split at capture or internal ledger: the structural decision

Wave and Orange Money do not expose a native multi-account split like Stripe Connect. So the 2026 practice in Senegal and Côte d'Ivoire is to capture 100 % onto the platform merchant account, immediately write one ledger line per vendor, then trigger a deferred payout via the Disbursement API. Paystack, by contrast, offers subaccounts with a split_code that truly divides the payment at the PSP level.

The split, line by line

Take a 10,000 FCFA order, 15 % commission, 1.5 % PSP fee borne by the platform. Here is the exact breakdown to write into the ledger as soon as the payment is validated.

The key: the vendor always sees 8,500 FCFA because the PSP fee is absorbed by the platform margin (1,500 → 1,350). If you pass the fee to the vendor, they only receive 8,350 FCFA — a commercial decision to lock in the contract.

Mini case study

Awa runs Marché Teranga, a creators' marketplace in Dakar with 40 vendors. In July 2026 the platform captures 3,200,000 FCFA over 380 orders, average commission 15 %. Her ledger computes 480,000 FCFA of gross commission. After the 1.5 % PSP fee (48,000 FCFA), her net margin is 432,000 FCFA. Vendors receive 2,720,000 FCFA in weekly payout, each line traced from capture. No dispute froze funds because retention was native.

FAQ

Should I compute the split at payout to simplify? No. Compute it at order time and store the line. At payout you only sum already-frozen lines, which avoids any drift when a partial refund happens.

Does Wave allow a native split like Paystack? Not in 2026. Wave and Orange Money require the internal-ledger + payout model via their Disbursement API, with a typical weekly transfer above a 5,000 FCFA threshold.

Who should bear the 1.5 % PSP fee? It is a contractual decision. The most vendor-friendly option is for the platform to absorb it on its margin (1,500 → 1,350 FCFA), but many pass it to the vendor.

What happens on a refund? Because the split is frozen at order time, you replay the line in reverse: the 1,500 FCFA commission is cancelled and the 8,500 FCFA vendor share is clawed back before the next payout.

How long between capture and vendor payment? In the Wave/OM model, expect a weekly cycle, i.e. up to D+7. Paystack subaccounts credit the vendor subaccount almost immediately.
