In their own words
Formstack Documents
Formstack Documents is a cloud, no-code document generation service that turns business data into dynamic files. Users can create templates with the AI-powered Document Builder or upload DOCX, PPTX, PDF and CSV templates. Data from CRMs, form builders, databases and other business systems populates those templates. Conditional logic can show or hide sections, while routing can combine files or generate multiple documents from one source. CRM data can produce proposals, contracts, invoices and reports. Bulk generation, data merging and an open REST API support larger workflows. Documents can be sent to Formstack Sign or DocuSign for electronic signatures. Listed protections include SSL, encryption, firewall protection, secure downloads and document encryption; Formstack says merged data is not stored. HIPAA and GDPR compliance are listed. The service runs on the web and through an API, with documentation and ticket support. A free trial is available, but there is no free plan.
