Tools to Manage Clients, Ads & Leads
For startup agencies aiming to keep costs down and run as lean as possible, you will at a minimum require a CRM. Working without a CRM may seem like a cost-saving option to start, but you will waste so many man-hours that growth will be impossible. I have always worked with GHL, as it is reasonably easy to pick up, and as you grow, you can add more integrations and easily use the white-label services to set up sub-accounts for clients.
