Ads create leads. A CRM makes sure those leads don't disappear. If you run paid traffic without a follow-up system, you're paying twice — once for the click, and again in lost revenue.
Set up a simple pipeline: new lead → contacted → qualified → booked → client. Automate the first response so no one waits longer than a few minutes.
Once your CRM and follow-up sequence is in place, ads become easier to measure and improve.
