Why Teams are Choosing FormAssembly Over Formstack
Smarter Data Collection. Highly-Rated Salesforce Integration. Unlimited Forms & Responses.
As your business grows, its data collection abilities need to scale with it.
And if your team depends on Salesforce for secure, scalable data collection, you’re going to hit roadblocks as your use cases and data needs become more complex. That is, of course, if the tools you use offer simple, limited Salesforce integrations.
FormAssembly delivers powerful Salesforce functionality, unlimited forms and responses, and better long-term value for data-driven teams. That’s why teams are choosing FormAssembly over Formstack.
FormAssembly’s Salesforce integration has been built for reliability, customization, and scale, providing a streamlined connection that reduces redundancy and handles complex use cases with ease.
“One of the cons we found with FormStack – double data storage needs. You’d have one record for the submission, one for the actual record created.”

Feature-by-Feature Comparison
Why an industry-leading Salesforce integration matters:
- Map data to any Salesforce object
- Avoid duplicate records and unnecessary API calls
- Get support for dynamic picklists, prefilled forms, conditional logic, and more
- Fully supported across integrations you need, like Salesforce Government Cloud, NPSP, and Health Cloud
No Arbitrary Limits on Forms or Responses
FormAssembly’s plans do not place a limit on the number of forms, responses, or documents you can use. As your company grows or your use cases become more complex, FormAssembly makes it easy to test and scale, whereas Formstack places limitations.
FormAssembly includes unlimited forms, responses, and connectors in every plan so that you can build freely and expand confidently.
“We needed a platform that wouldn’t nickel-and-dime us every time we launched a new form or campaign. FormAssembly gives us room to grow.”
Built for IT and Non-Coders Alike

These results go to show that FormAssembly helps teams get up and running faster, aided by support that’s included in every plan and options for consulting when you need it.
“FormAssembly gave our team the flexibility and integration depth we couldn’t find anywhere else. Their support is also exceptional.”
