Sales Invoice Tracker

This invoice tracker centralizes your billing operations across multiple sheets: customer database with company details, master invoice records with dates and tax rates, and itemized line items for each invoice. It uses VLOOKUP and formulas to link customers to invoices automatically, calculate totals with tax, and reduce manual data entry errors.

Ideal for small businesses, freelancers, and service providers who need to organize invoicing without complex accounting software. Manage customer contact information, track invoice status, and generate records for accounting and cash flow analysis all in one workbook.
