A dealer group in Arkansas had a Buick GMC store that was running smoothly. Fifty-five new units a month, healthy grosses, a team that was happy and productive. One top salesperson was selling 25 units a month and earning well. Most of the others sold five or six. Nobody was killing themselves, and the store was working.
Then the manufacturer said they needed to sell over a hundred new units a month. GM set the target, the owner took off the handcuffs, and the direction was clear: sell cars, even if you lose money on every new unit to get the volume.
They got the volume. Fifty-five became sixty-five, then seventy-five, then eighty-five. Two of the last three months they crossed a hundred. But the team was calling the GM and saying they couldn’t keep doing it. Selling fifty units when they used to sell twenty-five, and taking home the same check or less. The math wasn’t working for the people doing the work.

Why the Gross Play Works Until It Doesn’t
The model that store had built was designed for a different environment. Gross-based commission structures work beautifully when the market supports margins. The salesperson who sold 25 units at healthy gross was earning well precisely because the math of the old model rewarded holding gross. Every dollar they protected on the deal flowed through to their commission.
Then the economics changed. OEM volume targets tightened. Floor plan costs rose. The manufacturer’s LMA (local marketing association) programs required dealers to contribute more from invoice. Every new structural cost that came out before the bottom line reduced the gross available to the salesperson. The pie got smaller before anyone renegotiated how it was cut.
The salespeople on gross-based pay didn’t get a say in any of that. They just started noticing that the same deal that used to pay them $600 was now paying $380, because three different things had pulled money out of the gross before it got to the calculation. When volume went up alongside shrinking margins, the work roughly doubled and the paycheck stayed flat or went down.
As the director who shared this story put it: “They’re going, I am selling fifty when I sold twenty-five, and my paycheck’s the same or less. I am sorry. I love you, but I can’t do this anymore. I got to feed my family.”
What Pay Plan Modeling Would Have Changed
The store eventually made adjustments. They built volume-specific pay plan components, including a retro kicker back to unit one for hitting the new volume threshold, to ensure that selling more cars visibly meant earning more money. But they built those components reactively, under pressure, after the calls from the floor started coming in.
Modeling the transition before it happened would have changed the sequence. With deal-level compensation data and a pay plan modeling tool, the corporate office could have run the existing pay plan against the projected new volume and margin environment before the announcement.
They would have seen exactly what each rep’s earnings would look like if they doubled their units at compressed margins. They could have designed the new compensation structure to maintain earnings parity or better at the new volume level, and shown each rep the math before asking them to commit to it.
Instead, the discovery happened on the floor. Salespeople worked harder, took smaller paychecks home, and only found out the numbers didn’t work when they had already been living the reality for several months. The team stayed together because, as the story goes, they worked well together, but most groups ain’t gonna be that lucky.
How Do You Change a Dealership Pay Plan From Gross-Based to Volume-Based?
The transition from a gross play to a volume play requires changing the fundamental question the pay plan is answering. A gross-based plan answers: how much did this deal earn? A volume-based plan has to answer: how much did this salesperson contribute to the store’s strategic position this month?
Volume-based pay plans need a different set of components.
Flat commissions or gross percentages that pay the same on high-gross and low-gross deals protect the salesperson from market compression they can’t control.
Volume bonus tiers that pay meaningfully more for hitting higher unit thresholds give salespeople a reason to push hard even when individual deals don’t gross well.
Retro structures that apply the bonus rate backward to unit one create a compounding incentive so that the last units of the month pull the whole month’s earnings up.
The stair-step structure the store eventually built, where hitting the threshold triggered a kicker back to unit one, was the right design. The problem was that it was designed after the fact, after the trust was already damaged.
A salesperson who had spent three months earning less than they expected and then sees the new structure is appropriately skeptical. “Prove it to me in numbers. Show me what I would have earned under the new plan on my actual deals from last quarter.”
Answering that question precisely is what pay plan modeling is for.
The pay plan change itself is rarely the problem. The problem is the gap between what the dealer understood the change to mean for earnings and what the salesperson experienced when the checks came. Modeling closes that gap before it becomes a retention problem.

The Forces That Compress Gross and What They Mean for Pay
The Arkansas story isn’t unique. The same dynamic is playing out across the industry. Manufacturers are pushing volume targets to protect market share. Floor plan costs are rising. Competitive pricing pressure is compressing new vehicle margins. FTC disclosure requirements mean pricing has to be honored as listed, which limits late-stage negotiation. Each of these forces independently reduces the gross available to salespeople paid on gross percentage.
The cumulative effect is a pay plan designed for a market that no longer exists. A commission structure built when a healthy new vehicle deal grossed $2,500 front produces a very different outcome when the same deal grosses $800 after OEM contributions, LMA fees, and below-invoice pricing. The pay plan hasn’t changed, but the market has, and most pay plans can’t keep up.
What Visibility Changes About the Transition
One of the harder parts of the gross-to-volume transition is that salespeople can see their unit count but can’t see the gross compression that’s driving the change in their earnings. They know they’re working harder, but they don’t have a clear view of why the paycheck hasn’t kept up. Without transparency into the economics driving the decision, the most natural interpretation is that the store is taking something from them.
A pay plan transition that includes real-time visibility into earnings as deals close, combined with clear documentation of what the new structure pays and why, gives salespeople something to work with beyond suspicion.
The rep who can see that this deal paid $420 because the front gross was $950 after deductions, and who can see their running total for the month and how close they are to the kicker threshold, has information they can act on. The rep who finds out at washout that their check is less than they expected has nothing to act on but anger.

Frequently Asked Questions
How do you change a dealership pay plan from gross-based to volume-based?
The transition requires redesigning the pay plan’s fundamental incentive structure: replacing or supplementing gross-percentage commissions with volume-based tiers, retro bonuses, and fast-start incentives that pay meaningfully more for hitting higher unit counts. Before announcing the change, model it against each rep’s actual prior-period deals to show them what they would have earned under the new structure. Salespeople who see the new plan would have paid them more or equivalently are far easier to transition than those finding out after the fact that their earnings declined.
Why do salespeople resist switching from a gross-based to a volume-based pay plan?
Because they’ve seen the earnings impact before the pay plan was redesigned to compensate for it. In most gross-to-volume transitions, the market compression that makes volume necessary also reduces per-deal gross before the pay plan is updated. Salespeople experience higher workload and lower pay simultaneously, before any new volume incentives are in place to offset it. The resistance is a rational response to a real earnings decline, not a philosophical objection to volume selling.
What is pay plan modeling and why does it matter for dealerships?
Pay plan modeling means running a proposed pay plan structure against actual historical deal data to see what each salesperson would have earned under the new structure on their real deals. It answers the question every salesperson asks when a pay plan changes: “What does this mean for my check?” Before modeling, that question gets answered after the fact when the first paycheck under the new structure lands. With modeling, it gets answered before the announcement, which changes the entire dynamic of the transition.
How do OEM stair-step programs affect salesperson earnings?
OEM stair-step programs pay the dealer additional money for hitting volume thresholds, often retroactively to all units in the period. The problem for salespeople paid on gross is that stair-step pressure sometimes pushes dealers to sell below-gross or at-loss deals to hit thresholds, compressing the front gross available for commission. The dealer makes up the difference through the OEM incentive payment, but that payment doesn’t automatically flow through to the salesperson’s commission under a gross-based structure.
What should a volume-based dealership pay plan include?
A volume-based pay plan should include: a flat or tiered commission that doesn’t penalize salespeople for compressed margins on individual deals, a meaningful volume bonus tier that pays more for higher unit counts, a retro structure that applies the bonus rate backward to unit one so that hitting the tier improves earnings on every deal in the month, and real-time visibility so salespeople can see their progress toward every threshold throughout the month rather than finding out at washout.
How do you keep salespeople engaged during a gross-to-volume transition?
Three things matter most. First, model the new pay plan against their actual prior deals before the announcement, so they can see the math rather than being asked to trust it. Second, consider a transition period where they earn the better of the old or new structure for 60 to 90 days, which gives them time to verify the new plan is fair. Third, give them real-time visibility into their earnings under the new structure so they can see the incentives working as they sell, rather than waiting until washout to find out whether the new math worked in their favor.
