BillKazi - Mobile-first invoicing app for African freelancers
Published Feb 19, 2026
🔴 Problem Identified
African freelancers and small businesses are forced to use WhatsApp text messages or messy Excel sheets for invoicing because existing solutions don't support local currencies (RWF, KES, NGN) or understand local tax systems. Current invoicing tools are also desktop-focused when most African users primarily work on mobile devices.
💡 Proposed Solution
A mobile-first, free invoicing app that supports African currencies, auto-calculates local taxes (Rwanda 18%, Kenya 16%, Nigeria 7.5%), and allows invoice sharing via WhatsApp without requiring client sign-ups. The app is specifically designed for mobile-first users in African markets.
