This project demonstrates my ability to manage, organize, and process invoicing and billing data accurately using spreadsheet tools like Microsoft Excel and Google Sheets. The dataset includes 20 sample invoices generated over a three-month period, simulating real-world business transactions across multiple international clients.

Each record contains essential billing details such as invoice date, unique invoice number, client name, service description, quantity/hours worked, unit pricing, total amount calculation, and payment status (Paid, Pending, or Overdue).

Maintaining data consistency and structure

Handling financial records with attention to detail
