The verdict in three sentences
In Nigeria in 2026, Paystack charges 1.5 % + NGN 100 capped at NGN 2,000, while Flutterwave runs around 1.4 %, both settling at T+1. The cap makes Paystack very competitive on high-ticket baskets, where the effective rate falls well below 1.5 %. Integration takes 5 to 10 days and roughly 250,000 to 600,000 FCFA, and the confirmation webhook is mandatory to validate an order reliably.
Integration steps
A typical integration path runs like this:
| Step | Content | Estimated time |
|---|---|---|
| 1. Merchant account | Open Paystack/Flutterwave account, business KYC | 2 to 4 days |
| 2. API keys | Retrieve public / secret sandbox keys | 1 day |
| 3. Checkout | Payment button + redirect or inline modal | 2 to 3 days |
| 4. Webhook | Secure server-to-server confirmation endpoint | 1 to 2 days |
| 5. Testing | Live transactions + failure handling | 1 to 2 days |
The webhook is the heart of the system: it receives the server-to-server "payment confirmed" notification and triggers order validation. Never confirm an order on the buyer's browser return alone, which can be interrupted or spoofed.
Gateway cost comparison
For a merchant covering Nigeria and the wider region, here are 2026 orders of magnitude.
| Gateway | Transaction fee | Cap | Payout | Integration dev cost |
|---|---|---|---|---|
| Paystack (Nigeria) | 1.5 % + NGN 100 | NGN 2,000 | T+1 | 200,000 to 500,000 FCFA |
| Flutterwave (multi) | ~1.4 % | Per operator | T+1 | 250,000 to 550,000 FCFA |
| Moov Money (Benin) | ~1.5 % | 1,000,000 FCFA | T+2 | 250,000 to 600,000 FCFA |
| MTN MoMo (regional) | ~1.5 % | Per operator | T+2 | 250,000 to 600,000 FCFA |
Paystack tip: the fee is 1.5 % + NGN 100 but capped at NGN 2,000 per transaction. On a large basket, the effective cost drops well below 1.5 %, making Paystack very strong on high-ticket Nigerian sales.
Mini case study
Chidi, who runs a phone-accessories store in Lagos, commissions a Paystack + Flutterwave checkout for 450,000 FCFA, delivered in 8 days. He collects NGN 4,000,000/month. On Paystack with the NGN 2,000 cap, his high-ticket orders (above NGN 130,000) pay a flat NGN 2,000 instead of a rising percentage. Before, he lost roughly 12 % of baskets to clunky manual bank transfers. Recovering even half of those abandonments adds ~NGN 240,000/month in revenue, paying back the integration in under 4 months.

FAQ
How much does gateway integration cost?
Expect 250,000 to 600,000 FCFA of development depending on checkout complexity and operator count. Typical timeline is 5 to 10 business days, KYC included.
Is the webhook really mandatory?
Yes. It is the only reliable way to confirm a payment server-side. Without it, an order can be wrongly validated or lost if the buyer closes the browser.
Paystack or Flutterwave, which is cheaper?
Flutterwave is slightly lower at ~1.4 %, but Paystack's NGN 2,000 cap wins on high-ticket orders. Many merchants run both and route by basket size.
Can I test before going live?
Yes, a sandbox lets you simulate payments and failures. Always test failure paths (timeout, insufficient balance) before launch.
One gateway or several?
Several, ideally. A multi-gateway checkout cuts abandonment because each buyer pays with a familiar method. Kolonell wires Paystack, Flutterwave and local operators.
