SimplyPaye is a fintech collection ecosystem: Mobile Money (Orange Money, Airtel Money, M-Pesa), card payments, payment links, QR codes, a merchant dashboard and, beyond the apps, developer SDKs (Flutter/Dart, Node, Laravel, WordPress/WooCommerce). According to Gift Bambi Nzuzi, SimplyPaye now serves more than 50 merchants.

The problem

In the DRC, accepting digital payments means juggling several Mobile Money operators, each with its own integration, fees and reconciliation delays.

The solution

One integration to collect across every network, track transactions in real time in CDF and USD, and withdraw to Mobile Money from a merchant app.

My contribution

Creator of the product: architecture, transactional APIs and the merchant app published on the App Store. Author of the WooCommerce plugin on WordPress.org and the Flutter/Dart SDK on pub.dev.
