Formstack is a familiar name in the no-code productivity space. It covers forms, document automation, and e-signatures, with a native Salesforce AppExchange app and integrations with HubSpot and Microsoft Dynamics. For teams looking for a broad suite of digital workflow tools, it’s a widely adopted option. But organizations with complex Salesforce needs or compliance requirements have found that Formstack’s limits become business limits.
What is Formstack?
Formstack is a workplace productivity platform offering three core products: Forms for data collection, Documents for document automation, and Sign for e-signatures. A Suite bundle combines all three. The platform has a native Salesforce AppExchange app and integrates with HubSpot and Microsoft Dynamics.

FormAssembly vs. Formstack: Where Formstack falls short
Formstack’s Salesforce connector has documented architectural constraints. The connector requires double data storage — one record for the form submission, one for the object record created in Salesforce — which increases storage consumption. The Salesforce native connector is a separate product from the core offering. Using the unique URL prefill feature requires setting up a guest user criteria-based sharing rule for each Salesforce object, which counts toward Salesforce’s limit of 50 criteria-based sharing rules per object. Salesforce Experience Site page views are also subject to a 1,000,000 page view limit for guest users. The Salesforce Pro plan is not HIPAA-compliant, limiting options for regulated data collection. Pricing is based on both the number of admin users and the number of form submissions, which can make cost unpredictable as usage grows.
Why organizations choose FormAssembly instead
FormAssembly’s Salesforce integration is built with a different architecture — one that does not create the double-storage requirement or the sharing rule dependency that Formstack’s connector introduces. For organizations with large Salesforce deployments or high submission volumes, that architectural difference has meaningful operational and cost implications. FormAssembly also offers HIPAA compliance as part of its platform — not as an unavailable option on the standard plan — along with SOC 2, FedRAMP, and DoD IL4 certifications. For organizations that have outgrown Formstack’s limits, FormAssembly provides a path to more scalable, compliant Salesforce data collection.
