Dealers use the terms 'floor plan' and 'inventory financing' almost interchangeably in conversation, and that's where the confusion starts. They're related tools, but they're built to solve different shaped problems - and picking the wrong one means either overpaying for flexibility you don't need, or not getting the flexibility you do.
Here's the real difference: what each structure tracks, how it's priced, and which type of business actually needs which one.
Floor plan: unit-specific, vehicle-first
A floor plan finances individual, titled units. Each vehicle you draw against becomes its own tracked piece of collateral - the lender knows the VIN, the purchase price, and the exact day the clock started. When that specific unit sells, that specific draw gets paid off, typically within 24-72 hours of the sale.
Floor plans are built around audits (physical or GPS/photo checks confirming a floored unit is still on your lot) and curtailment schedules (mandatory principal paydowns at 30/60/90 days). It's a structure purpose-built for titled vehicle inventory, and advance rates run high - typically 90-100% of purchase price - because the collateral is so specific and trackable.
Inventory financing: broader, value-based
General inventory financing is looser by design. Instead of tracking individual units, it's a revolving line or term loan sized off a percentage of your total inventory value - commonly 50-80% - reported periodically rather than audited unit by unit.
This structure fits businesses whose stock isn't titled or individually serialized in the same way a car is: parts inventory, accessories, non-titled equipment, or a mixed lot of stock that doesn't map cleanly to VIN-level tracking. It trades the higher advance rate of a floor plan for lower operational overhead.
| Floor plan | Inventory financing | |
|---|---|---|
| Collateral tracking | Per-unit (VIN-level) | Aggregate inventory value |
| Advance rate | 90-100% of purchase price | 50-80% of inventory value |
| Typical cost | 9-13% APR + per-unit fees | 10-18% APR |
| Compliance mechanism | Audits + curtailment schedule | Periodic reporting |
| Best fit | Titled vehicle dealers | Parts, accessories, mixed stock |
Why many dealers actually run both
A used car dealer floors the vehicles on the lot and runs a separate inventory or working capital line for parts, accessories, and reconditioning stock that doesn't fit a per-unit structure. An equipment reseller might floor titled trailers while financing loose parts inventory on a general line.
The mistake to avoid is forcing one structure to do both jobs - trying to floor non-titled stock unit by unit adds audit overhead with no benefit, and trying to finance titled vehicles on a loose value-based line usually means a lower advance rate than a proper floor plan would give you.

What do you need funding for?
How to decide which one you need
- If what you're financing has a VIN or a title, a floor plan almost always gets you a better advance rate.
- If your stock is parts, accessories, or non-titled equipment, general inventory financing fits the shape of the collateral better.
- If you're running both titled and non-titled inventory, plan on two structures rather than forcing one to stretch.
- Match the reporting burden to your operation - audits are manageable at scale but overkill for a small parts department.
The metric that should drive the decision
Look at your GMROI (gross margin return on inventory investment) by category before choosing a structure. A category that turns fast at healthy margin justifies the higher advance rate and audit overhead of a floor plan. A slow-turning or thin-margin category rarely benefits from either - fix the category first.

FAQ
Can I use inventory financing to buy vehicles instead of a floor plan?+
Technically some lenders allow it, but you'll typically get a lower advance rate (50-80% vs. 90-100%) and less favorable terms than a purpose-built floor plan line, since the lender loses the per-unit tracking that makes vehicle collateral easy to value and recover.
Do I need a dealer license to get inventory financing?+
A floor plan line almost always requires an active dealer license. General inventory financing for parts or non-vehicle stock typically doesn't, since it's underwritten against inventory value and sales history rather than titled-vehicle compliance.
Which one is cheaper?+
Floor plan usually carries a lower APR (9-13% vs. 10-18%) because the collateral is more specific and easier to recover. But factor in per-unit fees and curtailment cash-flow impact before assuming it's automatically the cheaper structure for your situation.
Can a new dealer qualify for either structure?+
Yes, though new dealers typically start with smaller lines on both - often $50K-$150K to start - with tighter terms that expand as you build a clean audit and payment history.
