Invoice Generator

What this tool does

Invoice Generator builds a clean, professional invoice with your business and client details, line items, discount and tax, previewed live exactly as it will print, with a one-click "Print / Save as PDF" button using your browser’s own print dialog.

Creating a professional-looking invoice for a client usually means either paying for dedicated invoicing software or formatting one by hand in a word processor, more overhead than a simple one-off invoice needs.

This tool builds a clean invoice from your business and client details plus line items, with optional discount and tax, previewed live exactly as it will print, ready to save as a PDF directly from your browser’s own print dialog.

How to use Invoice Generator

1. Fill in your business details, the client’s details, invoice number and dates.
2. Add line items with quantity and rate.
3. Set any discount and tax percentages.
4. Press Print / Save as PDF and choose "Save as PDF" as the destination.

Tips for better results

• When the print dialog opens, choose "Save as PDF" (or "Microsoft Print to PDF" on Windows) as the printer/destination instead of an actual physical printer, to get a PDF file rather than a paper printout.
• Only the invoice itself is included when printing, the editing form above it is automatically hidden, so you get a clean, client-ready document without any extra UI in the PDF.
• Discount is applied to the subtotal before tax is calculated, matching standard invoicing convention (tax on the discounted amount, not the pre-discount total).
• All fields and line items are saved locally as you edit, so refreshing the page won’t lose your work in progress.

Common use cases

• Creating a one-off invoice for a freelance client or small business sale.
• Generating a professional invoice without subscribing to dedicated invoicing software.
• Quickly calculating a total with tax and discount applied correctly before sending it to a client.
• Producing a PDF invoice to attach to an email without needing a word processor.

Common mistakes to avoid

• Printing to an actual physical printer instead of choosing "Save as PDF" as the destination in the print dialog, resulting in a paper printout instead of the PDF file you likely wanted.
• Forgetting that discount is calculated on the subtotal, then tax is calculated on the discounted amount, not on the original pre-discount subtotal, this matches standard invoicing practice but is worth double-checking against your own requirements.
• Not double-checking the invoice number and dates before sending, since this tool doesn’t automatically increment invoice numbers across separate invoices you create.
