What it does
Formstack Forms is a paid online form builder for business requests, applications and other data collection. Prefilled links, conditional logic and approvals help connect a form to an existing process. Try the Forms service for 14 days without entering card details; a paid account is needed afterward.
Prefill, collect and route a request
Formstack can send a form with known details already filled in, apply conditional logic and route the response through approvals. Connections include Salesforce, HubSpot, Stripe and Airtable. This is useful for organizations collecting requests that need to reach an existing business system.
