Formstack
Secure forms, document generation and e-signature for regulated teams
Formstack is a forms & surveys tool for Small businesses and Enterprise, offered as paid ($99/mo). Founded in United States in 2006. Popular alternatives include Zoho Forms.
About Formstack
Formstack is a no-code forms and workflow platform founded in 2006 in Indianapolis by Ade Olonoh. Over the years it added Formstack Documents (from the WebMerge acquisition) and Formstack Sign, and bought Formsite. In 2025 the company renamed itself Intellistack and moved its headquarters to Denver, but Formstack products continue to be sold and supported under their own brand.
Formstack Forms covers drag-and-drop forms with conditional logic, payments, approval workflows, HIPAA-ready data handling, data encryption and offline collection through the Formstack Go mobile app. Documents turns submissions into filled PDFs or Word files, and Sign collects legally binding signatures, so a typical flow runs from intake form to generated contract to signature. Plans start with Forms for one builder user, Suite bundles all three products for three users, and Enterprise and Salesforce Solutions are quoted.
Formstack fits healthcare, education, government and financial teams that care about compliance and want forms, documents and signatures from one vendor. Jotform offers far more templates at lower prices, Typeform is better for conversational marketing forms, and Fillout gives modern forms with a generous free plan. Formstack has no free plan and per-form submission caps.
For Salesforce users, the native Salesforce forms product is the main reason to choose Formstack. Use the 14-day trial to confirm the submission limit per form fits your volume.

Our take
Formstack is a dependable choice when compliance and form-to-signature workflows matter more than price. If you only need forms, Jotform or Fillout will do the job for much less; choose Formstack Suite when documents and signatures are part of the process.
