Receipts are just invoices by another name — a few line items, a total, some party details. InvoicePDF generates a clean receipt PDF from JSON with the same one-call API, so you can email or store it instantly.
Set your line items and total; the generated PDF works equally well as a receipt. Free to try at the live playground.
The API is stateless — it returns the PDF bytes directly, so there's no storage to manage and nothing to clean up.
