# Contractors on Multiple Design Accounts
Contractors may be working with multiple design firms that use CollabMind. Each design firm would invite the contractors as they would any other collaborator.
The contractors dashboard includes a "Join Company" button that needs to be clicked to enter invitation codes from subsequent design firms after their first invitation.
The drop down menu at the top of the dashboard will allow the contractor to switch between design firm accounts. They will only be able to see one design firm's projects at a time; they cannot see all projects they're associated with at one time.
The multiple designs firms will have no view or knowledge that the contractor is invited to multiple accounts.
*Tip: Only Contractors can be added to multiple accounts, so if there is vendor, supplier, etc that you could imagine may be included by others on their accounts, then put them in the contractor role.*
