One store for a mixed business
The practical argument for a list this long is that most businesses are not one thing. A contractor runs a loader, a truck, a trailer and three pickups. A supplier runs vans and the owner's car. Splitting that across a commercial store and a repair shop means two relationships, two sets of records and two conversations about the same fleet.
Here it is one account. Fleet services holds the specifications and the schedule, and the rest of the list does the work, from an OTR change-out to an oil change.
