Most service businesses sell hours. Route-based businesses sell something far more valuable: a dense, recurring claim on a geography that compounds every time a stop is added to the truck. That structural difference, not the price of any single visit, is where these businesses are won or lost.
The route is the asset, not the service
Ask an owner what their pest-control or pool-service company sells and they will describe the service: the spray, the skim, the mow. Ask an acquirer what they are buying and they will describe the route: a list of recurring customers, clustered tightly enough that a technician can serve a dozen of them between sunrise and lunch. The service is a commodity. The route is the moat.
