Many businesses find Safaricom's M-Pesa for Business portal hard to use. KEPAS made an easier one. It is simple, saves time, and has extra features. It is built with our daraja-js tool, which makes it easier and better than using Safaricom's basic connection tools directly.

The plumber, the cleaner, the rider and the mechanic people need every day live and work around them. Clients have no way to reach them, and the workers have no way to reach the clients who would pay them. A client sees who is near, calls the worker from the app and watches them come on the map. The client pays with M-Pesa before the work starts, Wabi holds the money, and the worker is paid when the client confirms the job is done. Transport fares come from the real road distance and time. Wabi is an Android app for Kenya, built and owned by KEPAS Technologies. The code is private.

Every developer in Kenya who adds M-Pesa to an app runs into the same Daraja problems: unclear errors, callback issues, token expiry, and B2C mistakes that cost real money. The API works, but some behavior is not documented. Your code can pass in sandbox and fail in production. For example, phone numbers must be JSON numbers, balances come as one string with pipes between values, and callbacks do not retry. Most teams find this out during an outage. There was no typed library built from real production experience. So we built daraja-js from a real PayBill number. It fixes 14 problems we hit in production, so the next team does not have to learn them the hard way. Every fix is in the type definitions or the request layer. Anyone is free to use this SDK
