Automated Invoice Generator | Excel VLOOKUP + LOOKUP TABLES
Built a fully automated invoice system that eliminates manual entry:
How it works:
• Select Client → Name, Address, Email auto-fills via VLOOKUP from Clients Table
• Select Item Code → Description & Unit Price auto-fills from Products Table
• Line Total, Subtotal, Tax (10%), Total Amount calculates automatically
• Reference data hidden (Products & Clients tables) for easy updating
Formulas used: VLOOKUP, IFERROR, SUM, multiplication for totals
Result: Create a professional invoice in 30 seconds vs 15 minutes manually. Perfect for small business owners.
I can customize this with your logo, tax rate, and currency.
