What differs for built-in forms

For invoices delivered as PDF, templates are built in Word (4), a visual builder (3) and HTML (1). 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. Of these, 6 have a free tier.

Besides PDF, these tools for invoices also write DOCX (4), email (3) and XLSX (2). A submission to the tool's own form builds the document from the answers. Published starting prices run from $11 to $29 a month, the top end from Docupilot. Prices were checked on 20 Oct 2026.
