## Tools (4)

- `draft_invoice`: Price an invoice (subtotal, tax after discount, shipping, total) and get a builderUrl that opens the free AI Invoice Generator builder prefilled. The human can download a PDF there, or connect Stripe to get a pay link that accepts partial payments. Nothing is stored or sent.
- `list_invoice_templates`: List five editable sample invoices: hourly consulting, retainers, milestones, contractor labor/materials and deposit requests. Example rates in USD cents, not pricing advice. No account needed.
- `prepare_invoice_template`: Select a template by ID and add sender, customer and dates. Returns invoice JSON, calculated totals and an editable builderUrl. Example amounts need review. Nothing stored or sent.
- `render_invoice_pdf`: Generate a downloadable PDF artifact without a browser, account or storage. Requires sender/customer names, invoice number, dates and complete line items. Western European text only; unsupported characters or logos return an explicit error, use the web builder for those. Does not send invoices or process payments.
