What differs for Google Sheets

Each one maps Google Sheets fields into a template and saves a document sent for e-signature; 2 of the 3 build that template in Google Docs. All 3 read Google Sheets data without a Zapier, Make or n8n step in between. Add-ons run from the Extensions menu or on a schedule, and Apps Script can run on edit or on a time trigger.

You can try 3 of them on a free tier. Published starting prices run from $6.58 to $42 a month, the top end from Portant. When the output is a document sent for e-signature, the most common use cases are invoices (2), contracts (2) and certificates (2). Prices were checked on 20 Oct 2026.
