Paystack vs Flutterwave as an Aggregator in Kenya: The 2026 Decision Table

The verdict in three sentences

Paystack shines on developer experience and a polished web checkout, while Flutterwave covers wider on payouts, cross-border and multiple rails. The fee gap between them sits around 0.5 to 1%, which becomes significant beyond a few hundred transactions a month. The right choice depends less on the headline price than on your dominant channel: pure web checkout or multi-country, multi-rail collection.

The decision matrix

Before comparing fees, compare what each does well. Here is a 2026 order of magnitude.

Paystack wins when everything goes through a clean web checkout; Flutterwave wins when you collect across countries with many rails and need broad payouts.

Cost per 1,000 sales

To decide, normalize to a standard volume. Here is the 2026 estimate for 1,000 sales at NGN 9,000 (revenue = NGN 9M).

Over 1,000 sales, the fee gap is about NGN 45k/month, i.e. NGN 540k/year. That may favor Paystack on fees, but Flutterwave's cross-border reach can capture more markets and compensate.

Support and documentation

Support quality weighs over years of operation, not just at launch.

Mini case study

Wanjiru, who runs a ready-to-wear brand in Nairobi, sells 60% online and 40% cross-border, for 1,200 sales/month at NGN 9,000 (NGN 10.8M/month). With Paystack her web checkout recovers ~1.5 conversion points on the online channel, i.e. ~NGN 97k/month extra sales, but Flutterwave's cross-border reach opens a market worth ~NGN 120k/month. If cross-border matters, Flutterwave nets ~NGN 23k/month more despite higher fees. If she were 90% domestic web, Paystack would win on fees and checkout.
