Overview
Formstack Documents is a no-code document-generation module that merges data from forms, CRMs, and databases into templated contracts, invoices, and reports in DOCX, PDF, PPTX, or CSV format.
The product originated as WebMerge, an independent document-automation company founded in 2011, which Formstack acquired in April 2019 and rebranded into its current form as part of the broader Formstack platform.
Key Features
Core capabilities include a visual template builder with merge fields, conditional logic that changes document content based on incoming data, and automatic routing of finished documents to approval workflows or cloud storage like Google Drive and Dropbox.
Formstack Documents integrates with Formstack Forms as well as external CRMs and databases, and exposes an API for developers who want to trigger document generation from their own applications.
Pricing
Standalone plans start at $110 per month for the Starter tier (150 merges, 2 users, 10 templates), rising to $220 per month for Teams and $440 per month for Pro, with a custom-priced Enterprise tier for larger, compliance-heavy deployments.
Organizations that also need forms and e-signatures often choose Formstack's bundled Suite plan at $250 per month billed annually instead of purchasing Formstack Documents as a standalone subscription.
Key Features
Template-based document merge — Build a reusable document template once and automatically populate it with data from forms, CRMs, or databases.
Conditional logic in documents — Show, hide, or change document content dynamically based on the incoming data for each merge.
Multiple output formats — Generate finished documents as DOCX, PPTX, PDF, or CSV files depending on the use case.
Automated routing — Send generated documents automatically for approval or deliver them to cloud storage services like Google Drive or Dropbox.
CRM and database integrations — Pull data directly from external CRMs and databases in addition to Formstack Forms submissions.
API access — Trigger document generation programmatically from custom applications via the Formstack Documents API.
Reusable template library — Store and manage multiple document templates for different document types within a single account.
HIPAA-compliant Enterprise option — Custom Enterprise plans support HIPAA-compliant document generation for regulated industries.
