Mpesa Aggregated Merchant Agreement Form Download May 2026

1. What is an MPESA Aggregated Merchant Agreement? An MPESA Aggregated Merchant Agreement is a contract between Safaricom (or an authorized Payment Service Provider - PSP) and a business that wants to receive payments via MPESA. Under this model, the business does not need a direct contract with Safaricom. Instead, it signs up through an aggregator —a licensed third-party company that integrates multiple merchants under one master MPESA paybill/till number.
