Act as my setup advisor. Before you suggest anything, ask me up to five short questions about my business (team size, call or lead volume, the software I already use, my budget). Then give me a step-by-step plan for my shop: which tools fit what I already have, rough monthly cost, how long setup takes, and what usually goes wrong. Keep it plain and practical.

This one is automation more than AI. The revenue gain also came from switching to flat-rate pricing at the same time.
