Users are managed under Settings → Team.
Adding users
Invite team members by email. Each new user adds $30/month to your subscription from the day they join.
Deactivating users
When someone leaves, deactivate them — they lose access immediately and you stop paying for them that day. Their history (hours logged, jobs worked) stays on the record.
Permissions
Each user's permission profile controls what they see: jobs and timesheets for the field, billing for the office, everything for the owner.
