Supply-house credit at scale, the fleet, and inventory: the second truck's paperwork and the parts on it
Lesson 7 of 12~10 minFree previewCurrent as of September 2026
The second truck triples the paperwork of the first. This lesson is the three systems that grow with the fleet: supply-house credit when three people are buying on the account and the limit has to carry a $30,000 month; the fleet itself, including the rule most plumbers discover from a CHP officer, that a service truck with a gross vehicle weight rating over 10,000 pounds makes the shop a motor carrier that needs a Motor Carrier Permit, a carrier number, and a terminal inspection; and truck inventory, the parts that make a call a one-visit job and the count that keeps them from walking away.
What the full lesson covers
- Credit at scale: one account, named buyers with limits, job numbers on every ticket, the statement reconciled to the job folders weekly, and a limit request made before the big month, not after the ticket is refused.
- A truck with a GVWR over 10,000 pounds (most three-quarter-ton and one-ton service bodies) is a commercial motor vehicle under Vehicle Code 34601; operating it for the business requires a DMV Motor Carrier Permit and a CA carrier number (34620), commercial registration, and puts the shop in the CHP's Basic Inspection of Terminals program with driver and maintenance records.
- Every truck is lettered to B&P 7029.5 (name, address, number, 1.5-inch letters) the day it goes into service; every driver is on the commercial auto policy.
