User Instructions

1. Open the template and save a copy as your project-specific file.
2. Prefill the Client Directory and Product/Service Catalog sheets with master data.
3. To create a new invoice, enter data in the Invoice Master table. The system auto-calculates totals and fetches related values.
4. Data Version Management: Any change to an invoice triggers a new version entry in the Data Version Log with timestamp and user.
5. Use the Summary Dashboard for reporting, filtering by date range, client, or status.
6. To update a previously issued invoice (e.g., due to price adjustment), edit the record — system will log this change as a new version.
7. Regularly back up your file and consider using Excel's "Track Changes" feature for enhanced auditability.
