What Do I Need To Setup Group Leads For Clients & Make Money

You just have to be an admin or a moderator to your client's Facebook group so as to be able to approve new members.

You know, Group Leads works when you approve new members and am not sure if a moderator status can approve new members.

Secondly, as an admin, you would be able to set up the group onboarding questions the right way in case the client has not done so.

You can then bill your client(s) to help them generate leads from their Facebook group into Google sheet and their CRM

I hope this answers your questions.
