Many businesses still create invoices manually in Excel.
This project demonstrates how repetitive billing tasks can be standardized and automated using Excel Tables, XLOOKUP, Structured References, and reusable VBA modules.
Customer information, invoice numbers, payment terms, due dates, tax rates, currencies, and invoice calculations are automatically managed through a table-first architecture designed for maintainability and scalability.
Rather than being an accounting system, this project focuses on practical business process automation using Microsoft Excel.
