BPC PowerForms for SharePoint Licensing Information
PowerForms licensing is simple. A license is required for each SharePoint front-end server in a farm where user interaction occurs for PowerForms.
The initial license price includes one year of Basic (email based) Support and Software Assurance (free upgrades to all minor and major versions released during the year). Additional years of Software Assurance and Basic Support can be bought after the bundled year ends.
Every organization that purchases BPC PowerForms has the right to get development licenses for a single farm at a 20% discount. This is a full functioning license with no limitations other than it must be on a different farm from your production licenses.
