PLATFORM COMPARISON
FormAssembly vs. Formstack
If clean Salesforce data is the foundation of how your business runs, that architectural difference matters from day one.
FormAssembly writes directly to your Salesforce records. Formstack writes to its own database first and syncs from there.
Who each platform is for
Choose FormAssembly if:
- You run a mature Salesforce instance, manage regulated data, or build forms that update multiple Salesforce objects in a single submission.
- You need a platform whose architecture treats Salesforce as the source of truth from the moment a form loads.
Choose Formstack if:
- You want a single vendor across forms, documents, and e-signatures, and the breadth of the product line matters more than the depth of any single integration.

Deep object-first Salesforce architecture
When a form is submitted, FormAssembly writes directly to the Salesforce records you mapped — any standard or custom object, multiple objects in one pass, with prefill and bi-directional updates in real time.
Formstack offers two Salesforce options, both with tradeoffs. Its standard connector routes submissions through Formstack’s own database first, which can be the source of duplicate-record problems that admins routinely spend time reconciling. Its native “Forms for Salesforce” app removes that middleman but locks you into Salesforce-only publishing and requires a separate purchase.
FormAssembly has no such tradeoff. The same connector that writes directly to any Salesforce object also routes data to HubSpot, SharePoint, payment processors, Google Sheets, and more — no extra license, no deployment constraints.
Say “Hey” to Fai
Fai is FormAssembly’s built-in AI assistant. It generates branded, enterprise-ready forms and full workflows — including data routing, conditional logic, and integrations — in seconds. Every suggestion is transparent, editable, and optional, so your team gains the speed of AI without losing control of what ships.
Formstack offers an AI form builder that produces form fields from a prompt. It does not generate end-to-end Salesforce-integrated workflows, apply compliance controls, or operate as an agentic assistant — it produces a starting point rather than a finished, deployable workflow.
FedRAMP authorized. FERPA. Government Cloud.
FormAssembly holds FedRAMP authorization, HIPAA Business Associate Agreement coverage, SOC 2 Type II, PCI-DSS Level 1, and FERPA certification. FormAssembly’s enterprise infrastructure layer, runs on dedicated AWS environments with controls for PHI, data residency, and global compliance, and FormAssembly offers Gov Cloud plans for federal, state, and local agency workloads.
Formstack holds SOC 2, PCI, and HIPAA on Enterprise plans or HIPAA plans. It does not hold FedRAMP authorization and does not offer a Government Cloud plan. If your data falls under federal contract requirements or state and local government compliance frameworks, that gap makes the decision for you.
One platform built for forms-to-data, not a suite of products bolted together
FormAssembly is one platform. Salesforce mapping, conditional logic, document generation, and e-signature collection are built into a single workflow. Build a form once, route the data, generate the document, capture the signature, and update the Salesforce record without leaving the platform or licensing a separate product.
Formstack sells those capabilities as separate products in a suite — Forms, Documents, and Sign — each with its own licensing and configuration surface. Teams that buy the full suite still spend time stitching the products together. Teams that buy just one find the integration to the others less than they expected.
Independent reviewers say the same thing
FormAssembly ranks #1 in four SoftwareReviews categories: Ease of Implementation, APIs and Integration, Breadth of Features, and Ease of Customization. Formstack does not place in the top 10 for any of these four.

Frequently asked questions
How does FormAssembly’s Salesforce integration compare to Formstack’s?
FormAssembly writes directly to Salesforce records when a form is submitted — to any standard or custom object, across multiple objects in a single submission, with prefill from existing records and no intermediate database.
Formstack’s standard connector routes submissions through Formstack’s own database first, which is the source of the duplicate-record pattern that Formstack admins routinely report. A native but separately-sold “Forms for Salesforce” product removes the intermediate step — but it is a separately licensed product, and it only works inside Salesforce or Salesforce Experience Sites. Forms can’t be published externally.
FormAssembly has no such constraint. The same workflow that updates a Salesforce record can also route data to HubSpot, generate a document, collect an e-signature, update your Google Sheets, and send a conditional notification — all in one platform, without a separate license or a Salesforce-only deployment.
Does Formstack have FedRAMP authorization?
No. Formstack does not hold FedRAMP authorization and does not offer a Government Cloud plan. Federal agencies and contractors required to use FedRAMP-authorized systems for in-scope data collection cannot deploy Formstack for that work. FormAssembly is FedRAMP authorized and offers a Government Cloud plan for federal, state, and local agency workloads.
Is FormAssembly HIPAA compliant?
Yes. FormAssembly offers HIPAA Business Associate Agreement coverage and is built to handle Protected Health Information across enterprise plans. FormAssembly also holds FedRAMP authorization, SOC 2 Type II, PCI-DSS Level 1, and FERPA certification — making it one of a small number of form platforms certified to support healthcare, government, and education workflows on a single platform. Formstack offers HIPAA Business Associate Agreement coverage on Enterprise plans or HIPAA plans, but does not hold FedRAMP authorization or FERPA certification.
How long does it take to migrate from Formstack to FormAssembly?
Most teams complete a Formstack-to-FormAssembly migration within 30 to 60 days. The migration is typically slower than a Jotform-to-FormAssembly cutover because Formstack customers often have Salesforce mappings and workflow logic that need to be re-architected, not just rebuilt. FormAssembly’s Implementation Services team can lead the full migration, including form rebuilds, Salesforce object mapping, and workflow configuration. Every plan includes implementation guidance and a template library to accelerate the form-rebuild step.
Your Salesforce data deserves better than a sync.
Your Salesforce records are the foundation of how your business runs. The platform that feeds them should be built around that — not bolted on as one connector among many in a multi-product suite. FormAssembly is.
