Lease, Buy, or Broker? The Real Numbers on a Work Fleet
Whether it is two vans or a dozen trucks, how you put work vehicles on the road decides your taxes, your cash flow, and how many afternoons you lose at a dealership. Here is the actual math behind leasing, buying, and letting a broker source the whole fleet for you.

A fleet is not a bigger version of a personal car purchase. The rules are different, the tax code is on your side, and the mistakes cost more because you make them several times over.
Most small-business owners default to whatever their last vehicle was, or whatever the dealer pushes. That default quietly decides thousands of dollars in taxes and cash flow. So before you sign for the next van, here is what the numbers actually say.
The Tax Lever
Section 179 changed in your favor
The single biggest reason buying can beat leasing for a business is the tax code. Under the One Big Beautiful Bill Act passed in 2025, the write-offs got dramatically larger. If a vehicle is used more than 50 percent for business, you can deduct a large share of its cost the same year you put it to work instead of spreading it over five.

Not tax advice. Deduction amounts depend on vehicle weight, business-use percentage, acquisition and in-service dates, and your taxable income. Confirm your specifics with a qualified tax professional.
Here is what that means in practice. Buy a qualifying heavy work truck or van for the business and use it fully for the job, and a large portion of the purchase can come straight off your taxable income in year one. A long-bed pickup or a cargo van avoids the passenger SUV cap entirely and can often be fully expensed. That is a powerful reason to buy, if the cash flow works.
The tax code rewards buying a work vehicle. Your cash flow is what decides whether you can afford to take the reward.
The Tradeoff
Lease, buy, or broker: side by side
Buying wins on taxes and long-term equity. Leasing wins on cash flow and flexibility. A broker is not a third way to finance, it is how you source either one at a better price and without the dealership. Here is the honest comparison.

The row that owners underrate is time cost. Sourcing one vehicle at a dealership is an afternoon. Sourcing five is a week of your life you do not get back, and every one of those visits is a fresh chance to overpay.
The Multiplier
Why fleet mistakes cost more
Every dollar you overpay on a single car gets multiplied by the size of your fleet. The finance-office profit on an average deal runs around $2,500 per vehicle. Sourced through a broker who works your side, that is margin you keep, on every unit. Drag to see it add up.

The Answer
Where a broker changes the math
Decide lease or buy based on your taxes and cash flow. That part is yours and your accountant's. But whichever you choose, a broker changes three things at once: the price you pay, the time it takes, and the number of dealership trips, which drops to zero.
The takeawayLease or buy is a tax decision. How you source it is a savings decision. Do not let the second one happen by default.
We source any make or model for your business, structure it to lease or buy, and deliver each vehicle ready to work, so you keep the margin and the hours.
We work with owners on everything from a first work van to a growing fleet. For the leasing side specifically, our overview of business car leasing benefits covers how the payments and terms work, and our notes on fleet management best practices help once the vehicles are on the road.

Frequently asked questions
Is it better to lease or buy vehicles for a small business?
It depends on cash flow and taxes. Buying qualifying vehicles opens up Section 179 and 100% bonus depreciation, which can deduct a large share of the cost in year one, and you build equity, but it ties up more capital and you carry resale risk. Leasing keeps monthly costs predictable and payments are generally deductible, but there is no ownership and mileage is capped. High-mileage work trucks usually favor buying; tight cash flow or image-driven fleets often favor leasing.
How much can Section 179 save my business on a work vehicle?
For 2025 the total Section 179 cap is $2.5 million, heavy SUVs between 6,000 and 14,000 pounds are capped at $32,000, and 100% bonus depreciation applies to the remaining basis on qualifying vehicles placed in service after January 19, 2025. A qualifying heavy truck or van used fully for business can often be largely or fully expensed in year one. The exact figure depends on the vehicle and your tax situation, so confirm with your accountant.
What does a broker do for a business fleet?
A broker sources the vehicles for you, whether you lease or buy, negotiating price across dealer relationships instead of you visiting lots one by one. On a fleet, that saves the per-vehicle markup on every unit and eliminates the dealership time entirely, since vehicles are delivered ready to work. You still make the lease-versus-buy call with your accountant; the broker handles getting the vehicles at the right price.
