M-Pesa, POS & KRA eTIMS IntegrationPayments that hold up at peak volume.

M-Pesa · POS · eTIMS · E-commerce

We build and integrate payment systems for businesses where every transaction counts — high-volume M-Pesa processing, point-of-sale and KRA eTIMS tax compliance, reconciled end to end. Our team has built and run production systems that process large daily volumes of M-Pesa transactions.

What’s included

01

High-volume M-Pesa integration

Mobile money engineered for scale, where a missed or duplicated callback means real money.

  • STK Push (Lipa na M-Pesa Online), C2B Paybill and Till, B2C payouts and B2B
  • Queue-based callback processing that absorbs traffic peaks
  • Idempotency, so no payment is ever counted twice
  • Timeouts, retries and failed-payment handling
  • Automated reconciliation and settlement reporting
  • Monitoring and alerts on failed or delayed transactions
02

POS integration

Point-of-sale connected to payments, stock and the back office.

  • M-Pesa and card payments at the till
  • Inventory, pricing and sales synced across branches and outlets
  • Sales capture that keeps working when the connection drops
  • Integration with existing ERP, accounting and loyalty systems
03

KRA eTIMS integration

Tax compliance built into every sale, not bolted on at month-end.

  • System-to-system eTIMS integration via OSCU or VSCU, matched to your transaction volume
  • Tax invoices generated and transmitted automatically from POS, ERP or billing
  • Credit notes, item and stock data handled in the same flow
  • Error handling and retry so invoices are never silently lost
04

E-commerce & subscriptions

Owned sales channels with real checkout behind them.

  • Multi-tenant storefronts and custom domains
  • Product variations, inventory and shipping
  • Subscription plans, gifting and recurring billing
  • Card and PayPal alongside mobile money

Frequently asked questions

Can your M-Pesa integration handle high transaction volumes?

Yes. Our team has built and run production payment systems that process large daily volumes of M-Pesa transactions. We design for peaks with queue-based callback processing, idempotency so no payment is counted twice, automatic retries, and reconciliation against M-Pesa statements.

Can you integrate our POS or ERP with KRA eTIMS?

Yes. We connect POS, ERP and billing systems to eTIMS through system-to-system integration — OSCU or VSCU depending on your transaction volume — so tax invoices are generated and transmitted automatically with every sale.

Do you build POS systems or integrate existing ones?

Both. We integrate the POS you already use with payments, stock and eTIMS, or build a custom point-of-sale where off-the-shelf systems don’t fit how you operate.

Can you integrate M-Pesa into our existing website or app?

Yes. We add STK Push, Paybill/Till or B2C payouts to existing systems, including callback handling and reconciliation so every payment matches an order.

Our current payment integration drops or duplicates transactions. Can you fix it?

Yes. We audit the integration, trace where callbacks are lost or double-processed, fix it, and add monitoring so you know immediately if it happens again.
