## Automate it
The template is plain HTML and CSS. Use the View HTML button to copy it, fill it from your billing data, and POST it to /v1/pdf from a cron job, a webhook or an n8n flow. The PDF comes back in about a second or two.

## What a US invoice usually includes
- Your business name and address, plus the client's
- Invoice number, issue date and due date (for example Net 30)
- Line items with quantity, rate and amount
- Subtotal, sales tax (if you collect it) and the total due
- How to pay: ACH or bank details, a card link or a mailing address for checks

## FAQ
### Does it calculate sales tax?
It applies the tax rate you enter to the subtotal. It doesn't look up rates. Check your state's rules for what's taxable.

### Is the invoice saved?
No. Nothing you type is stored. Keep the PDF you download.
