What differs for built-in forms
Each one maps built-in forms fields into a template and saves a document sent for e-signature; 8 of the 13 build that template in a visual builder. 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. A submission to the tool's own form builds the document from the answers.
You can try 6 of them on a free tier. Published starting prices run from $15 to $250 a month, the top end from Formstack Documents. When the output is a document sent for e-signature, the most common use cases are contracts (13), onboarding packs (7) and letters (4). Prices were checked on 20 Oct 2026.
