What differs for built-in forms

For invoices built from answers to their own forms, the lowest paid starting price is $11 a month after conversion to dollars, from Gravity PDF. Published starting prices run from $11 to $29 a month, the top end from Docupilot.

These tools for invoices most often write PDF (7), DOCX (4) and email (3). Among them, 3 need Zapier, Make or n8n to read answers to their own forms, so they sit after the tools with a direct connection. A submission to the tool's own form builds the document from the answers. Prices were checked on 20 Oct 2026.
