User ID is the identifier for a specific user. Normally a person/individual using the application.
The Account ID, is the identifier for a group of users. This can be a specific department within a company, but can also be used for a company or subsidiary of a company within a certain country or region.
The Company ID is the identifier for a group of Accounts. For example, when a large company has multiple country organisations with each its own Account ID, we can link these Account ID’s together via a Company ID.
The Account ID is used so multiple users within a same group, location or department all can view and access the same dashboard. This works great in case you have multiple users working simultaneously on similar or even the same activities.
The Company ID and Account ID is mostly used for reporting purposes linking Account ID’s.
