Web app & WhatsApp bot for expense tracking

The Challenge

Small businesses and freelancers needed a simple way to track expenses without complex accounting software. Existing solutions required too much manual data entry, leading to incomplete records and poor financial visibility.

Our Solution

We built a web dashboard paired with a WhatsApp bot that lets users log expenses conversationally. The bot understands natural language, categorizes transactions automatically, and syncs everything to a clean web interface with charts and export options.
