Can I track which team member or partner each deal came from?

Yes. Since Levr is free for brokers, you can give everyone on your team their own login at no cost, so nobody has to share an account. To see where each deal originated, use tracked signup links: give each team member or partner their own link with their name set as the Source, and your account shows which deals came in through which link. That gives you clean attribution by person without any per-seat cost.
