When M-Pesa launched the concept of mobile money in 2007, the core use case was peer-to-peer transfers: workers sending money home to rural families, bypassing the expensive and slow formal banking system. This use case remains important. But the African mobile money ecosystem has evolved far beyond its original architecture into a sophisticated financial services infrastructure reshaping how businesses pay and get paid across the continent.
Total mobile money transaction values in sub-Saharan Africa exceeded $900 billion in 2023, up 22% year-on-year. The share attributed to purely personal P2P transfers has been declining as a percentage of total volumes, while merchant payments, bulk disbursements, and business-to-business transactions have grown rapidly.

Merchant Payments: The Commercial Frontier
Mobile merchant payments have become mainstream in Kenya, Ghana, Tanzania, and Rwanda. The infrastructure has standardised around QR code-based payment acceptance and merchant aggregators who onboard thousands of SME merchants onto payment platforms. Merchants who accept mobile payments see reduced cash handling costs, reduced theft risk, automatic reconciliation, and data records that banks can use to extend credit. Safaricom's Lipa na M-Pesa merchant platform processes over $1 billion in monthly transactions in Kenya alone, with 550,000 active merchant tills.
Supply Chain Finance via Mobile
The most transformative recent development is supply chain finance embedded in mobile platforms. Platforms like KCB M-Pesa, Stanbic's FlexiPay, and several B2B fintech applications allow large buyers (FMCG companies, distributors, manufacturers) to provide early payment to smaller suppliers using mobile money infrastructure as the settlement layer.
This solves a specific problem in African supply chains: large companies pay 60-90 day terms while small distributors cannot afford to wait that long. Mobile-enabled supply chain finance brings payment forward to 24-72 hours after delivery, funded by the large buyer's credit facility. Early results show the approach reducing working capital strain by 40-60% for enrolled SME suppliers.
