When installing any of the Clever Apps into a Business Central Environment, some additional dependent Apps will also need to be installed which work in conjunction with the main App.
When installing from Appsource into a SaaS Environment, the dependant Apps will be automatically installed for you. However, for On-Premise Environments, they will need to be manually installed. More information on this can be found here Clever App - Installing Apps into On-Premise Environments
The below Matrix shows the dependant Apps for each of our Clever Apps.
