All versions are provided by one managed package, available on the AppExchange.
By default, FormulaShare Lite will be installed to your org when installing from the AppExchange. Features of Enterprise or Unlimited can be unlocked remotely by our team without another installation or any changes being needed in your org. After purchase, we'll make a change which means after installation FormulaShare will include the features in your contract right away.
If you'd like to secure a trial of Enterprise or Unlimited either before or after installing, contact us at formulashare@cloudsundial.com, or register your interest and we'll be in touch.
