A full calendar is not the same as a profitable day. Six tickets spread across the metro can lose to four tickets in one zip code once you count windshield time. Dispatch density is how close jobs sit in time and geography — and it is one of the fastest levers small shops have on profit per hour.
Why a packed board still loses money
Travel is paid labor. Vehicle miles are a real cost. Overhead still attaches to every hour the truck is moving. A tech who spends 2.5 hours driving and 4.0 hours on site looks "busy" and still produces fewer billable dollars than a tech with 5.5 onsite hours and 1.0 hour of travel.
Cost both days in the job profitability calculator with honest travel and miles. The scattered day often shows thinner net margin and weaker profit per hour even if revenue is similar.
Cluster by window and zip, not by whoever called first
- Offer morning / afternoon windows by zone instead of exact times citywide.
- Hold a slot for a nearby add-on instead of taking a far call that splits the route.
- Batch membership visits and similar short tickets in the same neighborhood.
- Say no (or charge a trip premium) when a call sits outside today's density.
Rules that protect profit per hour
- Set a max drive time between consecutive jobs (for example 20–25 minutes) unless the ticket is high-contribution.
- Price distant work with a zone fee so the customer funds the extra miles.
- Review yesterday's map weekly: which zips paid, which only filled holes.
Density is not about refusing work forever. It is about not letting a random far call destroy an otherwise tight route.
Frequently asked questions
What is dispatch density for contractors?
It is how close jobs sit in time and geography. A packed calendar with long drives can lose to fewer clustered tickets once you count windshield time.
Why does a full board still lose money?
Travel is paid labor and miles are a real cost. A tech who spends hours driving produces fewer billable dollars than a tech with a tight route.
How do I cluster jobs without refusing work forever?
Offer windows by zone, hold a slot for a nearby add-on, surcharge distant calls, and review which zips actually paid — not which ones only filled holes.
