NEON by Vehicle AI · Use Case · Negative-Gross Deal Detection

Find the deals that closed under cost.Before next month's variance meeting.

Vehicle AI surfaces every used-car deal that closed under cost — with VIN-level loss attribution so you can find the root cause (over-allowance, trade discipline, ACV miscalibration) before the pattern repeats.

  1. Step 1 of 3

    Every closed deal gets a gross check.

    As soon as a used car closes, NEON compares the sale price to total cost.

  2. Step 2 of 3

    The ones under cost get flagged.

    Within hours, not at month close, with the loss on every VIN.

  3. Step 3 of 3

    The pattern becomes coaching.

    When over-allowance jumps, it lands in your morning briefing with the gross it gave up.

The problem

You don't see the loss-leaders until they're already 9 deep.

Most dealerships find out about negative-gross used car deals at the end of the month, when accounting reconciles. By then you've closed the next 30 deals, and whatever caused the first nine to lose money has probably caused another six.

Vehicle AI flags them daily, by VIN, with the loss broken down: how far over ACV was the trade, what was the recon variance, where did the front-end gross actually go. So you can fix the rule — not just count the damage.

And we don't surface false alarms: new-car deals routinely show negative gross in the DMS feed because manufacturer holdback, OEM incentives, and floorplan credits aren't booked into cost — those recover through separate accounting. Our negative-gross queue is used cars only.

How NEON solves it

From signalto action.

  1. Step 1 · Step 1

    Every closed deal gets a daily gross check.

    As soon as a used car closes, Vehicle AI compares sale price to total cost (acquisition + recon + holdback + reconditioning). Negative-gross deals get flagged within hours, not at month close.

    Capital Trap: $1.6M tied up in overstocked Rogues
    New Rogues are 36% of inventory value but only 15% of recent sales — a 20-point imbalance strangling cash flow. Dealer trade or aggressive lease push to rebalance.

    Missed Opportunity: INFINITI QX60 inventory running dry
    You moved 21 QX60 units last month and are down to your final 7 — 10 days of supply at current pace. Secure additional inventory before you lose front-end gross.

  2. Step 2 · Step 2

    Loss attribution by root cause.

    Per deal: how much of the loss came from over-allowance on trade, how much from recon variance, how much from price erosion. Patterns become visible: "every loss this month came from over-allowance on Civics with high ACV."
