FAQs

What format does the CSV file need?

The CSV should have three columns in this order: Customer Name, Invoice Amount, Invoice Date (e.g., YYYY-MM-DD). The first row should be a header, as the tool is programmed to skip it.

Is my financial data safe?

Yes. All processing and calculations are performed directly in your web browser. No invoice data ever leaves your device or is sent to a server.

Can I export the report?

Currently, the tool displays the report on-screen for immediate analysis. You can use your browser’s print-to-PDF function to save or share a copy.

Is this calculator free to use?

Yes, it’s completely free with no restrictions or hidden costs.

Can I edit an invoice after adding it?

The current version does not support editing an entry. To make a correction, simply re-upload a corrected CSV file or refresh the page to start over with manual entries.
