What differs for built-in forms

For onboarding packs delivered as e-sign documents, templates are built in a visual builder (5), Word (3) and a fillable PDF form (2). Among them, 2 need Zapier, Make or n8n to read answers to their own forms, so they sit after the tools with a direct connection. Of these, 4 have a free tier.

Besides e-sign documents, these tools for onboarding packs also write PDF (7), DOCX (3) and PPTX (2). A submission to the tool's own form builds the document from the answers. Published starting prices run from $15 to $250 a month, the top end from Formstack Documents. Prices were checked on 20 Oct 2026.
