Can I manage multiple businesses independently without sharing login credentials?

I want to avoid sharing logins, passwords etc.

Yes you can. If you setup Cogsworth for someone else, you can simply invite them as a staff member and make them administrator. This will give them full authority over the business, but you will be able to login and view the business separately.

You can also invite secretaries and call centre staff to view and manage your calendars and bookings this way also.
