The problem: every missed call is a lost booking
A one-chair shop runs on the barber's time. When you're mid-cut, the phone rings and you can't answer it. The client hangs up, tries Instagram, maybe sends a DM. Maybe they book somewhere else.
For a shop with a 5-star reputation and real demand, that's not a minor inconvenience — it's a leak in the funnel that happens every single day.
