Formstack Documents alternative: which one fits
Formstack Documents suits teams already collecting data in Formstack Forms or Salesforce who want documents without code: Word, Excel, PowerPoint, fillable PDF or drag and drop builder templates, If/Else logic and loops, Data Routes that send one request to several templates, and delivery to Formstack Sign, a CRM or SharePoint. Its trust center lists SOC 2 Type II, ISO 27001, HIPAA and PCI DSS, and the Suite bundles forms with unlimited electronic signatures. It fits operations and healthcare teams that turn form submissions into contracts, letters and order forms. Its entry price is $250 a month for 250 deliveries, Documents is not sold on its own, data is hosted only in the US, and there is no editor to embed in your own product or a dedicated or on premises option.
PDF Generator API starts at €8 a month for 50 credits and costs €52 for 1,000, so volumes that need the $250 Suite on Formstack fit a lower plan, and each credit covers a document of 1 to 5 pages. It adds a drag and drop embeddable template editor your customers use inside your app, web forms and signature fields and document signing on the same platform, HTML to PDF, fillable forms, watermarks and encryption, accessible PDF output, electronic invoices in XRechnung and Factur-X, ISO 27001 certification with GDPR and HIPAA compliance, shared cloud in the US, EU, UK and Australia, 8 SDKs, and dedicated or on premises deployment. To compare, rebuild one of your Formstack Documents templates during the free trial and send it the same data.
