How this tool works

This generator calculates subtotal, tax, and total, then formats a simple invoice with invoice number, dates, payment terms, service details, and client information.

Formula or template logic

subtotal = quantity * rate; taxAmount = subtotal * (taxPercentage / 100); total = subtotal + taxAmount; dueDate and paymentTerms are added to the invoice text but do not change the total

Example use case

Use this for a simple one-line invoice after a project is approved or completed, then copy, download, or print the invoice from your browser.

Frequently asked questions

Is this payment processing?

No. It only creates invoice text and a preview. It does not collect payments.

Can I print the invoice?

Yes. Use the print action to open your browser print dialog.

Can I add payment terms?

Yes. Add a due date and payment terms so the copied invoice is clearer for the client.

Does it store invoices?

No. The tool runs in your browser and does not save invoice data to a database.

Should I add tax?

Add tax only when it applies to your business and location.
