Frequently Asked Questions

Is the invoice legally valid?

Yes, the PDF invoice is legally valid for business transactions. However, check your local regulations as some jurisdictions may require specific fields or tax registrations.

Currently, the tool doesn't save data between sessions. We recommend keeping a copy of invoice details in a separate document or spreadsheet for future reference.

How do I add my company logo?

This version generates text-based invoices. To add a logo, you can edit the PDF using a PDF editor or add it to your company letterhead before printing.

The tool uses $ symbol by default. While you can't change the currency symbol, you can add currency information (e.g., "USD", "EUR") in your notes section.

What happens to my invoice data?

All data stays in your browser. Nothing is uploaded to servers or stored. Your invoice information is completely private and secure.

Can I edit the invoice after generating PDF?

Once generated, you'll need to make changes in the tool and regenerate the PDF. Alternatively, use PDF editing software to modify the downloaded file.

You can add unlimited line items. The PDF will automatically adjust to accommodate all items. For very long invoices, consider splitting into multiple pages.
