If you are not sure where to start, begin with the gap between a new inquiry and the first reply. Build one simple flow: when a form or call comes in, send a short, friendly message right away, tag the lead, and create a task for a person to follow up. It is easy to test, easy to explain to a client, and it solves a real problem. Once that works reliably, add reminders and then reporting. Starting small makes it easier to get each piece right.
