CashFlow Tracker – Automated M-PESA Business Analytics Platform

CashFlow Tracker (Simux Tech Product)
February 2026
5 months

CashFlow Tracker is a WhatsApp-powered financial analytics and business cash flow management platform built specifically for Kenyan SMEs and informal businesses.

The platform allows users to forward M-PESA transaction messages directly to a WhatsApp bot, where the system automatically parses transaction data, categorizes income and expenses, tracks balances, generates reports, and provides real-time business insights.

The project was designed to solve one of the biggest challenges facing small businesses in Kenya: poor financial visibility caused by manual bookkeeping and fragmented transaction tracking.

The platform combines financial analytics, automation, WhatsApp integration, M-PESA payment processing, subscription billing, reporting systems, and cloud infrastructure into a scalable SaaS platform tailored for African SMEs.

CashFlow Tracker was architected as a production-ready fintech solution with secure payment processing, automated subscriptions, webhook infrastructure, PostgreSQL data persistence, analytics dashboards, forecasting systems, and scalable deployment architecture.

The Challenge

Millions of SMEs in Kenya operate without proper accounting systems due to:

  • Manual bookkeeping processes

  • Low technical literacy
  • Lack of real-time analytics
  • Poor cash flow monitoring
  • No centralized reporting systems
  • Difficulty tracking income versus expenses
  • Limited access to affordable fintech tools

Most existing accounting platforms were too complex, expensive, or poorly adapted for the Kenyan market and mobile-money ecosystem.

  • Exportable reports (PDF, CSV, Excel)
  • Subscription lifecycle automation
  • PostgreSQL analytics database
  • Cloud-based deployment architecture
  • Secure API and webhook handling
  • Real-time notification systems
  • Business performance dashboards

The system was designed to provide enterprise-level business visibility while remaining extremely simple for non-technical users.
