When creating campaigns, projects, contact lists, agents and products, you can associate them with an office. This is an administrative flag which can later be used to filter views and reports to show only that office. Unlike sponsors, offices are not mandatory, so you can choose to use them or not.
The name "office" suggests these are locations, and indeed they can be used as such. You can have campaigns associated with offices for your Paris-based team and your Amsterdam-based team, for example. However, offices in LeadDesk do not have to be location based. You might instead use different offices for different departments or teams.
When you create a new Team Leader, Manager or Sponsor, if you assign them an office, they will only be able to see campaigns, agents and products associated with that office. If you assign them no office, they will only be able to see campaigns, agents and products that also do not have an associated office.
