The verdict in three sentences
Payment confirmation (the customer paid) and settlement (the money is in your usable account) are two different moments, sometimes 72 hours apart. In Lagos, Nairobi and Accra, Paystack settles next-day (T+1) while some aggregators run T+2 to T+3 with a 0 to 10 % rolling reserve. The real cost is not the headline 1 to 1.5 % fee — it is the working capital you cannot touch while you wait to restock.
What settlement really means
When a customer completes a Paystack or M-Pesa payment, your dashboard shows "success" within seconds. But that money first sits in the provider's technical account. The payout to your bank or wallet follows its own schedule: frequency, cutoff time, minimum amount and fee.
Two stores with identical revenue can face very different cash positions depending on the provider. The one paid T+0/T+1 restocks the next morning; the one on T+3 waits — and on fast-moving goods, that means stockouts.
Settlement window comparison (2026 order of magnitude)
| Provider | Settlement window | Payout fee | Minimum payout | Cutoff | Rolling reserve |
|---|---|---|---|---|---|
| Paystack (Nigeria) | T+1 next-day | 1 % (capped) | NGN 100 | Midnight | 0 % |
| Flutterwave | T+1 to T+2 | 1.4 % | NGN 100 | 22:00 | 0 to 5 % |
| M-Pesa Paybill/Till (Kenya) | Near-instant to T+0 | 0 to 1.5 % | KES 10 | Rolling | 0 % |
| M-Pesa B2B | T+0 | 1 % | KES 10 | Rolling | 0 % |
| MTN MoMo (Ghana) merchant | T+1 to T+2 | 1.5 % | GHS 1 | 18:00 | 0 to 5 % |
The rolling reserve deserves attention: some aggregators hold 5 to 10 % of your takings for 30 to 60 days to cover disputes or refunds. On a month at 5,000,000 FCFA equivalent, an 8 % reserve means roughly 400,000 FCFA frozen.
The hidden cost of tied-up cash
| Scenario (5,000,000 FCFA equiv./month) | Average cash tied up | Restocking impact |
|---|---|---|
| Paystack T+1 | ~ 160,000 FCFA | Near-daily restock possible |
| Flutterwave T+1/T+2 | ~ 250,000 FCFA | Restock every 2-3 days |
| Aggregator T+3 + 8 % reserve | ~ 800,000 FCFA | Weekly restock, stockout risk |
The longer the window and the higher the reserve, the more you are quietly financing your provider. At a 20 % net margin, tying up 800,000 FCFA instead of 160,000 FCFA means giving up roughly 1.5 to 2 stock turns per month.
Mini case study
Chidi runs a cosmetics store in Lagos. He sells about 5,000,000 FCFA equivalent per month, 25 % net margin, with products that turn every 10 days. On an aggregator at T+3 with an 8 % reserve, he had on average 800,000 FCFA tied up.

Moving most collections to Paystack (T+1, 0 % reserve), his tied-up cash dropped to about 160,000 FCFA. He freed 640,000 FCFA of permanent working capital. At 25 % margin, reinvesting that in extra stock earns roughly 160,000 FCFA of additional margin per month, or about 1,920,000 FCFA a year — without selling a single extra unit, just by settling faster.
FAQ
Is the 1 to 1.5 % fee the provider's real cost?
No. The headline fee is visible; the cash-flow cost is invisible but often larger. An 8 % reserve held for 60 days costs far more in lost opportunity than a 1 % payout fee.
How long before Paystack money is available?
Usually T+1: a payment received today is typically settled to your bank the next business day, with no rolling reserve on standard accounts.
Why do aggregators hold a reserve?
To cover disputes, fraud and refunds. It is legitimate but negotiable: a clean 3-6 month history often brings the reserve down from 10 % to 0-3 %.
Which provider if my cash is tight?
Favour the shortest window and lowest reserve, even if the nominal fee is slightly higher. On fast-moving goods, T+1 usually beats saving 0.5 % on fees.
Can I combine several providers?
Yes, and it is recommended: M-Pesa or Paystack for speed, another rail for international card coverage. Each order is routed to the optimal channel.
