Templates
Each one is a single API call with your JSON. Every page below was rendered by the engine from the template's sample data.

Invoice
Clean, modern invoice with line items, discount, tax, amount-due panel and payment details. Multi-page with a repeating table header.

Receipt
Proof-of-payment receipt with an amount-paid panel and PAID badge, payment method and transaction ID, compact line items, discount, tax, and a support or refund-policy note.

Quote
Quote or estimate for agencies and service businesses: line items grouped into sections with subtotals, discount, tax, terms and a client acceptance block with signature lines. Multi-page with a repeating table header.

Credit note
Credit note against an earlier invoice: credit-amount panel with issued/applied/refunded status, original invoice reference and reason, credited line items, tax and how the credit will be applied.

Statement of account
Customer statement for a period: balance-due panel with opening, invoiced, paid and closing balances, an activity table with a running balance, an optional aging summary and payment instructions. Multi-page with a repeating table header.

Certificate
Landscape course-completion or achievement certificate with an accent frame, issuer mark, large serif recipient name, one or two signature lines, seal, credential ID and verification link. Always exactly one page.

Generic document
Generic layout for any JSON: header from title/from/to, a details panel, then one section per key. Objects become key/value grids, arrays of objects become tables. Used automatically when no template is chosen and none matches.
