What each one actually does
Flutterwave is a licensed processor that handles card acquiring, transfers, and settlement across several African markets. They own the rails for the payments they process.
PayKato is not a processor and is not a bank. PayKato provides invoicing, payment links, a merchant dashboard, KYB onboarding, and itemised settlement records — routing payments to licensed processor and payout partners. Specific partner availability is confirmed during onboarding.
