M-Pesa POS Integration Guide 2026

M-Pesa Integration for Kenyan Businesses

Kenyan consumers prefer M-Pesa over cash. Your business needs to accept mobile money to stay competitive. Turning away customers leads to lost sales.

Not all integrations offer the same quality. Native integration is fast and reliable. This guide shows the right way to accept M-Pesa.

What is M-Pesa POS Integration?

M-Pesa POS integration allows your system to accept payments directly. No separate devices are necessary.

The Process

1. A customer selects items.
2. The cashier totals the sale.
3. The customer chooses M-Pesa.
4. The customer enters their phone number.
5. The system sends a push notification.
6. The customer enters their PIN.
7. Verification happens instantly.
8. The receipt prints automatically.

Total time is 15 to 30 seconds.

Technical Details

POS systems connect to Safaricom APIs. Native integration is built into the software. Instant confirmation and automatic reconciliation are standard. Third party plugins often add fees and delays.
