We're deciding whether to add a crew with nothing but a gut feel
The phones have been busy for a couple of months and the owner starts thinking about a third install crew or a fifth van. Nobody runs the numbers on how many booked calls that crew needs each week to cover payroll, fuel, and the truck payment, or how many months it will take to get there. The decision gets made off how busy the summer felt, not off what the schedule actually shows.
A part-time CFO's job is to turn that gut feel into a model: current close rate, average ticket, and call volume from ServiceTitan or Housecall Pro run forward to show exactly when a new crew breaks even and what it costs the business to get there.
Adding a crew before the call volume supports it commonly costs a shop 20,000 to 30,000 dollars in unrecovered payroll and vehicle expense during the months it takes to ramp up, cash that has to be pulled from somewhere else in the business.
