What You Get

Everything your business needs
to accept M-Pesa

No POS machine. No till hardware. Just an Android phone or Windows PC — and InforPay handles the rest.

📲

Works on Any Android Phone

No POS terminal needed. InforPay runs on any Android phone or tablet your staff already has. Install the app, enter your store key, and start accepting M-Pesa in minutes.

🏦

Your Own Private Gateway

InforPay runs against a private gateway server hosted exclusively for your business. Your M-Pesa credentials, your transaction data — stored on your server, not shared with any third party.

📲

STK Push Payments

Send a payment prompt directly to your customer's phone. They enter their M-Pesa PIN and the transaction completes instantly — no USSD codes to remember.

🏪

Till Number Payments

Customers pay to your till number at their own pace. InforPay automatically detects the payment and matches it to the right transaction on your device.

🖨️

Instant Bluetooth Receipts

Print a professional receipt via Bluetooth thermal printer the moment payment is confirmed. Each receipt carries the M-Pesa code, amount, and your business details.

📱

Android POS App

A clean, fast Android app your cashiers will actually use. Simple two-tap flow: enter amount and reference, tap Pay, done. Works on Android tablets and phones.

🖥️

Windows Desktop App

A full-featured WinForms desktop application for Windows PCs. Same M-Pesa STK Push and Till flows, local SQLite storage, and receipt printing — no browser required.

👥

Staff Management

Create cashier and admin accounts. Cashiers process payments; admins access settings and reports. Default admin lets you set up a fresh device before syncing staff.

📊

Transaction Reports

View payment history by date range. See every M-Pesa receipt number, customer phone, amount, and reference. Export-ready for your accounting.

🔒

Secure Architecture

Your M-Pesa credentials never leave your private gateway server. The Android app communicates only with your gateway — no third-party cloud stores your business data.

⚡

Multi-Device, Multi-Cashier

Run four or more devices simultaneously. Atomic payment claiming ensures two cashiers can never accidentally confirm the same till payment.

🧾

Reference Tracking

Every transaction requires an invoice or registration number. Payments are matched to their reference — giving you a clean audit trail from day one.

Private Gateway

Your data lives on
your server — full stop.

Most payment solutions route your transactions through a shared third-party platform. InforPay is different. We set up a private FastAPI gateway server exclusively for your business — your M-Pesa API credentials, your customer phone numbers, and your payment history stay on infrastructure you control.

01
Dedicated instance

Your gateway is provisioned exclusively for your business. No shared queues, no shared databases.

02
Direct Safaricom integration

The gateway registers directly with Safaricom's Daraja API under your Till or Paybill credentials — no middleman takes a cut.

03
Real-time callbacks

Safaricom fires M-Pesa confirmation callbacks directly to your gateway. Payment status updates reach your app in under a second.

04
Multi-device atomic claiming

When four devices work simultaneously, the gateway ensures each payment is claimed by exactly one device — no double-printing, no race conditions.

The Flow

From sale to receipt in four steps

InforPay is built around a simple, repeatable flow your team masters in minutes.

1

Enter the Sale

Cashier enters the amount, customer's phone number, and invoice or registration reference.

2

Send Prompt or Await Till

STK Push sends a payment request to the customer's phone. Till mode waits for the customer to pay to your till number.

3

Payment Confirmed

M-Pesa confirms payment in real time. InforPay receives the callback from Safaricom and updates the transaction status instantly.

4

Receipt Printed

A receipt with the M-Pesa code, amount, reference, and business name prints automatically via your Bluetooth thermal printer.
