Formstack review

Formstack targets organizations where forms feed documents, signatures and Salesforce records. The Forms plan at $83 per month paid annually includes one builder user, 25 forms, 1,000 submissions per form and 2GB of storage. Suite at $250 per month paid annually adds Documents and Sign, with 3 builder users, 100 forms, 5,000 submissions per form, 250 document deliveries a month and unlimited eSignatures. Salesforce teams can buy native forms with dynamic prefill and document generation powered by Salesforce data, and Enterprise brings SSO, custom SLAs and unlimited users and submissions. Integrations cover Salesforce, Stripe, PayPal, HubSpot and Airtable, and submissions can be routed for approval. The downsides are price and access: there is no free plan, the entry tier has a single builder, and simple signup or feedback forms cost far less elsewhere. It earns its place for regulated intake and document-heavy processes.
