Built forTop Quality AutomotiveCairo, Egypt
ERP system built for Top Quality Automotive to manage warehouse operations, tax handling, and invoice generation. The system supports complex business logic where each product can be purchased with or without tax, affecting invoice calculations and financial workflows. Built from scratch as a full enterprise solution.

Problem solved
Products could be purchased and sold under different tax conditions, making invoice totals, stock valuation, and financial records difficult to manage consistently. The business needed traceable rules rather than repeated manual calculations.
