A commercial account is valuable when the work, price, collections and service obligations are documented. A list of local employers or a verbal relationship is not contracted fleet revenue.
Define the service and authorized users
Specify vehicle types, services, hours, frequency, identification, exclusions and who may approve washes. Assess dimensions and compatibility before accepting unusual vehicles. Staff need a consistent process rather than a familiar driver’s verbal authorization.
Separate paid account work from complimentary services or internal arrangements. Track visits and invoices by customer and period so the buyer can see how revenue was earned.
Evaluate collection and concentration
Request signed agreements, billing history, aging, disputes and actual collections. A large monthly invoice can create a cash gap if payment is slow. Compare direct service costs with realized net revenue, not just quoted contract value.
Measure exposure to the largest accounts and identify renewal, cancellation and price-change rights. A concentration risk can remain even when the account has paid reliably for several years.
Review whether the relationship transfers
Ask counsel about assignment and required consent in an asset sale. Confirm who actually controls purchasing at the customer. Do not assume personal relationships or a government contact become the buyer’s contracted business automatically.
Keep a transition plan with authorized contacts, billing setup and service continuity. Public procurement and other specialized arrangements require review of the actual solicitation and contract; this page does not promise government fleet eligibility.
Model capacity before adding volume
Compare the proposed visit schedule with retail queues, staffing and equipment capacity. A lower contract price may be acceptable at one time of day and costly at a peak period. Test profitability with the actual service obligations and collection timing.
