## How it works

Invoice total = sum(line items) − discount + tax. Line items are description, quantity, and unit price.

## Worked example

An invoice can list website tune-up, monthly support, tax, terms, invoice number, amount due, and a note before you copy or print it.

## Assumptions

- This is a local browser invoice draft, not accounting software.
- Tax, invoice numbering, payment terms, and recordkeeping requirements vary by jurisdiction.
- Review the output before sending and keep your own records.

## Common questions

### Is this a full invoice system?

No. It creates a local invoice draft. It does not store clients, track payment status, or file taxes.

### Does the site store invoice data?

No. The output is generated in your browser and should be copied, printed, or saved by you.

### What should I verify before sending?

Business details, client details, taxes, terms, legal requirements, and payment instructions.
