Each tier of settings inherits the settings from all of the tiers above it unless explicitly expressed otherwise. As of v3.3 of Blesta, company and system settings have an 'inherit' field which determines whether or not that field can be inherited.

For example, if we would like to retrieve all of the client group settings for some client group, the result would include all client group settings, all company settings for that matching client group, and all system settings. In this case, if a client group setting and a company setting shared an identical key, the client group setting would be used because it takes precedence through the hierarchy over inherited duplicate keys.
