An SOT audit, subject-of-trust, is your floorplan lender’s field team physically confirming that every VIN on your curtailment schedule is actually on your lot, unencumbered, and not already sold. It’s not a paperwork exercise. When a unit fails, it usually fails for two reasons at once: a title problem and a curtailment miss, on the same car, because both tend to pile up on the inventory nobody has looked at in months.
What an SOT audit actually checks
Floorplan financing works on a trust structure: the lender owns the vehicle’s title (or holds a lien against it) until you sell it and pay off that unit’s advance. The AFC dealer glossary describes the audit as the lender verifying “the inventory and any other information provided by a dealer to make sure that all compliance requirements are met,” specifically that floored vehicles are physically where they’re supposed to be. The same source also names the failure mode this whole checklist exists to prevent.
Failure mode
A vehicle sold but not paid off, sometimes called "sold out of trust," is a serious offense that can carry civil liability and, if intentional, criminal exposure.
In practice, an auditor (sometimes a third-party field service, sometimes the lender’s own risk team) shows up with your current floorplan schedule and walks the lot, comparing VIN to VIN. Three outcomes per unit:
- Verified: car is there, matches the schedule, no exceptions.
- Missing/unaccounted: car isn’t on the lot and there’s no documented reason (in transit, at a body shop, on a test drive with a paper trail).
- Sold, unpaid: the car left, there’s a bill of sale or a deal jacket, and the lender hasn’t received payoff. This is the one that escalates fastest.
A clean SOT audit is boring by design. A bad one becomes the reason your credit line gets pulled, your advance rate drops, or, in a deal, the reason a buyer’s counsel starts asking questions that weren’t in the original data room.
Why a failed unit is rarely just one problem
Here’s the part most prep checklists skip: the units that fail SOT audits are almost never the ones that were sold yesterday. They’re the aged units, the ones sitting past 60 or 90 days, the trade-ins that got parked in the back row while someone chased the title paperwork. That’s not a coincidence.
Key insight
Curtailment and title defects have the same root cause: nobody is actively managing that VIN.
A car that’s been sitting long enough to miss a curtailment payment is also a car whose deal jacket has probably gone stale. If it came in as a trade with a lien that took three weeks to release, or a name mismatch on the assignment of ownership that got kicked back once and never resubmitted, that title work often stalls at the same time the unit ages past its curtailment window. The physical audit surfaces the missing car; pulling the thread on that VIN surfaces the title exception and the curtailment gap in the same conversation.
This is why we frame curtailment and title tracking as one operational problem, not two departments’ separate headaches. If your CIT and title-clerk workflows only talk to each other at audit time, the audit is where you find out how much has been silently accumulating.
The pre-audit checklist
Run this before the auditor’s field visit, not after the notice arrives.
| Check | What you’re confirming | Where it usually breaks |
|---|---|---|
| VIN-to-schedule reconciliation | Every unit on the lender’s floorplan schedule matches your physical lot count | Units sold but not yet reported to the lender |
| Curtailment currency | No unit is past its day 31/61/91 curtailment obligation without a paid principal reduction | Aged units nobody flagged before the deadline; see our breakdown of what changes at each curtailment stage |
| Sold-unit payoff status | Every unit marked sold in your DMS has a matching payoff sent to the lender | Payoff delayed behind a stalled title or a funding backlog |
| Title location | You can produce, or account for, the physical title (or ELT record) for every floored unit | Titles sitting in a lienholder release queue, or misfiled after a trade |
| Off-lot units | Demos, loaners, units at recon or a body shop, and consigned units are documented with a reason and expected return date | Undocumented off-lot movement reads as “missing” to an auditor |
| Duplicate or double-floored VINs | No VIN is financed with two lenders simultaneously | Trade-ins floored again before the prior lender’s release posted |
| Aging report review | Days-supply on floored units is visible and current, not just pulled quarterly | Nobody owns the aging report between audits |
| Exception log | Every known discrepancy has a written explanation ready before the auditor asks | Discrepancies get explained verbally, then forgotten, then look worse on the next audit |

The M&A angle: why this checklist matters beyond compliance
For a single-store operator, a failed SOT audit is a credit-line problem: a lower advance rate, a shortened floorplan term, or a lender that starts showing up more often. For a dealer group in the middle of a sale or acquisition, it’s something else entirely: it becomes an indemnification fight.
Buyer due diligence in a dealership M&A deal almost always includes a floorplan and title reconciliation, because it’s the fastest way to find liabilities that don’t show up on a balance sheet. A pattern of curtailment misses signals cash management stress. A pattern of title defects signals unclear ownership on units the buyer would be acquiring. When both show up on the same VINs, which they usually do, that’s not two footnotes; it’s evidence the inventory operation wasn’t tightly run, and buyer’s counsel will price that risk into the purchase agreement, typically as an indemnification carve-out or a holdback tied to exactly this kind of exposure.
That’s the non-obvious part of preparing for an SOT audit: you’re not just satisfying your current lender. A clean, current, well-documented floorplan and title reconciliation is the same evidence a buyer’s diligence team will ask for later, whether that’s next quarter or in three years. Running this checklist quarterly, not just when a notice arrives, means you’re never assembling that record under pressure.
Audit rights aren’t unlimited in adjacent compliance contexts either, which is a useful reminder of why waiting to fix exceptions is expensive. Under Florida’s dealer warranty statute, a manufacturer can’t audit warranty and incentive claim payments made to a franchised dealer more than once each calendar year (Fla. Stat. § 320.696). That’s a different audit, a different party, and a different set of payments than a floorplan SOT check, but the underlying discipline is the same: audit rights are time-bound on paper, and exceptions don’t get cheaper to resolve by leaving them for whenever the next audit window happens to open.
How to actually run the reconciliation without adding headcount
Most of this checklist is a matching problem: floorplan schedule against physical inventory, DMS sale status against lender payoff records, deal jacket status against title location. That’s exactly the kind of cross-referencing that stalls when it depends on one person remembering to check three systems before every audit cycle. If your title and curtailment tracking already live in disconnected spreadsheets and DMS screens, an AI coworker built for dealership back-office work can run that VIN-by-VIN reconciliation continuously instead of quarterly, and flag the units where a title exception and a curtailment deadline are converging before an auditor finds them together.
FAQ
What does SOT stand for in a floorplan audit?
SOT stands for subject of trust: a physical verification that the inventory a dealer has reported to its floorplan lender actually exists and sits where the dealer says it does. The floorplan trust structure means the lender holds an interest in each unit until it’s sold and paid off, and the audit confirms that structure still matches reality.
What does a failed floorplan audit typically reveal?
In practice it’s rarely a single clean problem. Failed units tend to be aged inventory that’s both behind on curtailment and carrying an unresolved title issue, a lien release that never posted, a name mismatch, a payoff sent late, because the same neglect that lets a unit miss a curtailment deadline also lets its title paperwork stall.
How often should a dealer run this reconciliation internally?
At minimum, monthly, tied to your curtailment cycle rather than waiting for the lender’s audit notice. Units that are already aging past 60 days deserve a weekly check, since that’s the window where curtailment misses and title delays are most likely to be compounding on the same VIN.
Does a failed SOT audit affect anything beyond the floorplan line?
Yes. Beyond the immediate risk of a reduced advance rate or a shortened term, a documented pattern of failures becomes part of the record a buyer’s diligence team reviews in an acquisition or recapitalization, and it can shape indemnification terms in the purchase agreement.
