What this invoice generator is for
This tool generates an invoice with automatic calculation of the subtotal, tax, and total amount due, based on the line items you enter. It avoids manual calculation errors and produces a clean document, ready to send to your client.
Practical use cases
- Freelancers and contractors: bill clients for completed work with a professional-looking document.
- Small businesses: issue invoices without needing dedicated accounting software.
- One-off sales: quickly produce an invoice for a single transaction.
How to use this tool
- Fill in your company's information (name, address, tax ID, contact).
- Add the client's name and address.
- Enter the invoice number, issue date, and due date.
- Choose the applicable tax rate, or enter a custom one.
- Add one line per service with its quantity and unit price: the total is calculated automatically.
- Add your payment terms as a note, then download the PDF.
Key benefits
- Automatic calculation of the subtotal, tax, and total: no rounding or manual entry errors.
- As many line items as you need, with a customizable tax rate.
- No sign-up, no limit on how many invoices you can create.
Practical tips
- Use a continuous, chronological numbering scheme (e.g. INV-2026-001, INV-2026-002…) — this is a legal requirement in many jurisdictions.
- Keep a copy of every invoice you issue; legal retention periods commonly run several years, depending on where you operate.
- If you're exempt from charging tax, note that exemption clearly instead of applying a tax rate.
Good to know
An invoice should identify the issuer and the client, carry a unique number, show the issue date, list services with quantities and unit prices, and state the tax rate applied. Check the mandatory disclosures specific to your business and location (tax IDs, tax regime notes, etc.) with an accountant if you're unsure — this tool helps with formatting but doesn't replace accounting advice. Everything you enter stays in your browser, and the PDF is generated locally on your device.
Common problems
If the total looks off, check each line's quantity and unit price, and confirm the correct tax rate is selected. If your business is exempt from a particular tax rate, choose "0%" or a custom rate and add a clarifying note explaining the exemption.
