Most dealers describe their floorplan as a line of credit, and that description is close enough to be dangerous. A general line of credit lends against a borrowing base and lets you manage the balance however you like. A floorplan line lends against specific serialized units, tracks each one separately from the day it is advanced, forces principal reductions on a calendar you do not control, and sends someone to physically confirm the collateral is still standing on your lot. The mechanics are different enough that operators who manage a floorplan like a revolver end up surprised: usually on a curtailment date, sometimes during an audit.
This piece walks through the machinery in the order it actually affects you: what gets advanced, what does not, how the curtailment schedule drains cash on aged units, what the line costs once every component is counted, and why the audit exists. None of it is complicated. It is just accounting that runs per unit rather than per account, and per-unit accounting behaves differently when inventory slows down.
What the line is, mechanically
A floorplan facility is a secured revolving line with a total credit limit, drawn one unit at a time. When you acquire a vehicle, the lender advances funds against that specific VIN. The advance becomes a tracked sub-balance with its own origination date, its own accrued interest and its own maturity behavior. Your total outstanding is the sum of those sub-balances, not a single blended figure.
The collateral position is usually a first-priority security interest in the inventory, with the title held or controlled by the lender until the unit is paid off. That title control is the part dealers underestimate. It means you cannot deliver clean paper to a retail buyer on a unit that has not been paid off, which is why the sold-unit payoff clock is the tightest deadline in the whole arrangement.
Advance rate: what the line actually funds
The advance is calculated against a defined value, not against your asking price. Depending on the facility and the source of the unit, that reference value is typically the auction purchase price, the actual cash value on a trade appraisal, or a book value from a recognized guide: whichever the credit agreement names. Advance rates vary by lender, program, unit type and dealer history.
What matters operationally is the gap between what the line advances and what the unit truly costs you to put on the lot. Auction fees, transport, reconditioning, safety inspection and any title or registration work are frequently outside the advance, or capped well below actual spend. That gap comes out of working capital on every single acquisition, and it is the reason a dealer with an approved line can still run out of money.
Curtailments: the forced paydown clock
A curtailment is a required principal reduction on a unit that has been on the line past a defined age. It is not a penalty and it is not optional. It exists because collateral depreciates: the lender wants its exposure on a given VIN to fall roughly in line with the unit's declining wholesale value, so that if it ever has to repossess and remarket, the loan is not underwater.
Time-based curtailment
The common structure sets an initial free period, then requires a fixed percentage of the original advance to be paid down at defined intervals thereafter, with the percentage often stepping up as the unit ages further. Specific triggers, percentages and intervals vary by lender, program and dealer, and are set out in your agreement rather than by any industry standard.
The important property of a curtailment is that it is a cash event with no revenue attached. You are writing a check on a car that has not sold. That is why a slow month compounds: the same aging that stops units from selling is what triggers the payments that drain the account you would use to buy fresher inventory.
Sale-triggered payoff
The other principal trigger is the sale itself. When a unit retails, the full advance plus accrued interest is due within a short defined window, often measured in a small number of business days after delivery or after contract funding, depending on the agreement. Missing that window puts you sold out of trust, which is the single most serious status in inventory finance and is covered in detail in the audit article.
What the line costs once you count everything
Dealers usually quote their floorplan cost as a single rate. The real cost has several components, and the ones that are not expressed as a percentage are easy to forget until you total the annual statement.
| Component | How it is charged | What drives it |
|---|---|---|
| Interest | Daily accrual on the outstanding advance | Balance outstanding and days held |
| Origination or floor fee | Flat amount per unit floored | Number of units, not their value |
| Curtailment | Scheduled principal reduction | Unit age, not unit value |
| Unused line fee | Periodic charge on undrawn capacity | Limit size versus utilization |
| Audit and inspection cost | Per inspection, often passed through | Inspection frequency, lot count |
| Title and administrative fees | Per unit or per event | Title handling and payoff processing |
The per-unit flat fee deserves attention because it inverts the usual intuition. A flat floor fee is a much larger effective cost on a $9,000 unit than on a $34,000 unit, and it is a much larger cost on a unit that turns in three weeks than on one that turns in three months, because it is not amortized over time. Dealers running high-volume, low-price inventory often find the flat components matter more than the stated rate.
Why the audit exists
The lender's security is a physical object it cannot see. Everything else (the advance, the title control, the curtailment schedule) assumes the specific VIN it funded is still where you said it is, unsold. The audit is the only mechanism that confirms the assumption. An inspector walks the lot against the outstanding VIN list, verifies each unit physically, and asks for documentation on anything not standing there. Units at a body shop, on demo, at a satellite lot or in transit are all legitimate, but they must be evidenced on the spot. Frequency varies by lender and by dealer history, and inspections are generally unannounced by design.
The covenants sitting behind the line
A floorplan agreement is more than an advance mechanism. It usually carries the ordinary furniture of a commercial credit facility: minimum net worth or working capital tests, restrictions on additional indebtedness, reporting requirements for financial statements, and cross-default language linking the floorplan to your other obligations.
The additional-indebtedness clause catches operators most often: a dealer under cash pressure takes a short-term advance to cover a curtailment and breaches a covenant in the facility the advance was meant to protect. Read that section before you need it. Note also that most floorplan lines carry demand features, the limit you have today is not a contractual guarantee of the limit you will have next quarter.
How the lender reads your aging report
The aging report is the single document that describes your relationship. It buckets every floored unit by days on the line, and the shape of the distribution tells the credit desk more than your income statement does.
A healthy report is front-loaded: most units young, a thinning tail, almost nothing in the oldest bucket. A deteriorating report grows a bulge in the middle and then a permanent tail. The tail is what triggers the reviews (reduced limits, tighter advance rates, more frequent inspections) because a lender reading a fat tail concludes that either your buying is wrong or your pricing is wrong, and both are its problem.
What to keep current if you want the line to stay clean
- A live aging report you actually read weekly, not the one you print for the auditor.
- A title log showing exactly where every title sits and its status.
- Payoff confirmations filed against every sold unit, matched to the delivery date.
- Written documentation for every unit not physically on the main lot.
- Repair orders open and current for anything at recon or at a body shop.
- A curtailment calendar projected out ninety days, with the cash required by week.
- Monthly financial statements produced on time, in the format the agreement specifies.
- A reconciliation between your DMS inventory and the lender's outstanding VIN list.
What actually breaks a floorplan relationship
Relationships rarely end over a single missed payment. They end over patterns, and the patterns are predictable. Chronic aging is the first: a tail that never clears signals that the inventory strategy is not self-correcting. Repeated curtailment lateness is the second, because it says the operation cannot fund its own schedule.
The third is discrepancy: units the auditor cannot find, titles that are not where the log says, sold units with no payoff. A single documented exception with a clean explanation is normal. Several exceptions in one visit changes the file's character from an operating relationship to a workout candidate, and that shift is very hard to reverse.
Is a floorplan line the same as a business line of credit?
No. A general line of credit lets you draw and repay against an overall limit at your discretion. A floorplan advances against specific VINs, tracks each one separately, and forces principal paydowns based on how long a unit has been on the line. It also comes with physical inspection of the collateral, which a working capital line does not.
What happens if I miss a curtailment payment?
Treatment varies by lender and by agreement, but the usual sequence is a late fee, then a hold on new advances, then heightened inspection frequency. A single late curtailment with an explanation is usually manageable. A pattern generally triggers a facility review, and reviews more often reduce limits than raise them.
Why does the lender hold my titles?
Title control is how the lender secures its position in a specific unit. Because you cannot deliver clean title to a retail buyer until the advance is paid off, holding titles also enforces the sale-payoff window. Some facilities use electronic title systems instead of physical custody, but the effect is the same.
Does the flat per-unit fee matter compared to the interest rate?
On fast-turning or lower-priced inventory it frequently matters more. A flat fee does not scale with unit value or shrink with a fast sale, so on a unit that sells in three weeks it can exceed the interest accrued over the same period. Compare total cost per unit over your actual average days to sale, not the headline rate alone.
How often should I expect an audit?
Frequency varies by lender, facility size and dealer history, and inspections are generally unannounced. What is consistent is that frequency rises when aging deteriorates or when a prior inspection produced exceptions. Treat inspection cadence as a signal about how the lender currently reads your file.
Does floorplan debt count against me on other credit applications?
It appears on your debt schedule and an analyst will see it, but a well-managed floorplan is generally read as ordinary trade financing for the business model rather than as leverage. What raises concern is aging concentration, curtailment delinquency, or floorplan balances that do not reconcile to physical inventory.
Where to start
Pull your current aging report and your credit agreement and put them side by side for an hour. Find your curtailment triggers and percentages, the sale-payoff window in business days, and the additional-indebtedness clause. Then project your curtailment cash requirement out ninety days by week. Most operators have never done that projection, and it is usually the number that explains why the account feels tight in months when sales were fine.
If you want the exposure analyzed against your actual turn rather than a schedule on paper, which units cost money to keep, what the tail does to your capacity, what the line looks like restructured: that is the review the dealer desk runs.
