Floor Plan Tracking Software for Car Dealers: What Actually Works

Most DMS platforms — Frazer, DealerCenter, DeskManager, AutoManager — do not automatically track floor plan interest per vehicle. Here is what does.

If you use floor plan financing to stock your inventory, your DMS should be tracking the daily interest cost on every car. Most dealer management systems — Frazer, DealerCenter, DeskManager, and AutoManager — do not do this automatically. Dealers using these platforms carry floor-planned inventory for 60, 90, or 120 days and never see the true holding cost reflected in their deal profit. They close deals thinking they made $2,000 when they actually made $1,100 — or less.

This page does two things: explains exactly why floor plan tracking matters, and gives you an honest table showing which DMS software actually does it automatically versus which ones leave it to you. One platform in this comparison built automatic floor plan tracking from the ground up. The others did not.

Short answer: Of the major independent dealer DMS options — Frazer, DealerCenter, DeskManager, AutoManager, and FoxDMS — only FoxDMS automatically calculates daily floor plan interest per vehicle and subtracts it from your deal profit. Every other platform requires manual tracking.

The Core Problem: What Dealers Are Missing Without Floor Plan Tracking

Here is a real scenario that plays out constantly in wholesale dealerships:

Example Deal — What You See vs. What Is Real
Purchase price $12,000
Sale price $14,000
Looks like profit $2,000
Days on floor plan 90 days
Floor plan rate 2% / month
Floor plan interest (90 days) −$900
Actual profit $1,100

The dealer above thought they made $2,000. They actually made $1,100. That is a 45% overstatement of profit on a single deal. Multiply that across 20, 30, or 50 deals a year and the cumulative blind spot is significant — potentially tens of thousands of dollars in misreported profit that affects how you price vehicles, how you evaluate your operation, and whether you realize a particular car was actually a wash.

The fix is straightforward: your DMS should know your floor plan rate, know when each vehicle was acquired, and automatically add the daily interest cost to the vehicle's total cost. When you close a deal, the profit should already reflect how long the car sat. Not every DMS does this.

Which DMS Tracks Floor Plan Interest Automatically?

This is the core question. The table below is the honest answer. No sales spin — just what each platform does and does not do when it comes to automatic, per-vehicle, daily floor plan interest tracking.

Software Auto Floor Plan Tracking Method Notes
FoxDMS ✓ Yes — Automatic Daily calculation per vehicle Enter your rate once; system tracks interest from purchase date and includes it in every deal's profit automatically
Frazer DMS ✗ No Manual entry required Frazer does not calculate floor plan interest per vehicle per day; dealers must add this cost by hand or maintain a separate spreadsheet
DealerCenter ✗ No Not built for floor plan tracking DealerCenter is designed for retail dealers; it does not natively track per-vehicle floor plan costs; wholesale dealers on this platform track interest outside the system
DeskManager ≈ Partial / Manual Manual cost entry DeskManager allows adding costs to a deal, but does not automatically calculate daily floor plan interest; the dealer must calculate and enter it
AutoManager ✗ No Manual AutoManager does not include automatic floor plan interest tracking; dealers on floor plan must account for this cost separately
Spreadsheets ✗ No Fully manual A spreadsheet does whatever you build it to do — but it requires you to build and maintain it, and most dealers do not have a formula that updates daily per vehicle

The takeaway is simple: if you are using any platform other than FoxDMS and you carry floor-planned inventory, your profit numbers are incomplete by default. You are either doing extra manual work every deal, or you are not accounting for the cost at all.

How FoxDMS Floor Plan Tracking Works

FoxDMS built floor plan tracking as a core feature, not an afterthought. Here is the full process:

  1. Enter your floor plan rate once Go to your dealership settings and enter your monthly floor plan interest rate. You set this one time. FoxDMS applies it to every floor-planned vehicle going forward.
  2. Add a vehicle with its purchase date When you add a vehicle to inventory, you enter the purchase date and floor plan amount. This becomes the start date for the interest clock. The system knows when the car came in.
  3. The system tracks daily interest automatically Every day the vehicle sits in inventory, FoxDMS calculates and accumulates the floor plan interest cost. You do not need to log in, update a spreadsheet, or enter anything. The number grows automatically as the car ages.
  4. Profit is accurate in every deal When you create a deal on that vehicle, the accumulated floor plan interest is already included in the vehicle's total cost. The gross profit you see in the deal is the real number — after floor plan, after expenses, after pack.

That is the entire workflow. No spreadsheet on the side. No end-of-month reconciliation. No surprise when you look at your P&L and wonder where the money went.

What Dealers Without Tracking Actually Do

Dealers using Frazer, DealerCenter, AutoManager, or spreadsheets are not ignoring floor plan costs entirely — most are working around the problem in one of three ways. None of them work well.

The Spreadsheet Column
Maintain a separate Excel sheet that tracks each car's floor plan start date, calculates daily interest, and produces a running total to manually add to the deal when you close it.
Fails when: the spreadsheet is not updated daily, when cars are forgotten, or when a second person handles deals without knowing the process.
The Month-End Estimate
Ignore floor plan costs deal-by-deal and estimate total floor plan interest paid at the end of the month from the lender statement, then allocate it loosely across deals.
Fails when: fast-turn vehicles look artificially profitable, slow vehicles look the same as fast ones, and individual deal accuracy is impossible.
Ignoring It Entirely
Treat floor plan interest as an overhead cost like rent or insurance — paid from the business account each month and never attributed to individual vehicles.
Fails when: you try to price vehicles correctly, evaluate which car types are most profitable, or understand why a good month on paper still felt tight.

Each of these workarounds requires extra work, introduces error, or sacrifices per-deal visibility entirely. The goal of dealer management software is to eliminate this manual overhead — and on floor plan tracking specifically, most DMS options have not delivered on that promise.

Is Floor Plan Tracking Worth $39 per Month?

The Simple Math on Whether FoxDMS Pays for Itself

FoxDMS costs $39/month — $468 per year. That is the full price. No per-user fees, no setup costs, no contract.

Consider what happens on a single miscalculated deal. A dealer who sold a vehicle for $2,000 gross but did not account for $900 in floor plan interest effectively lost $900 without realizing it. If floor plan tracking reveals even one deal per year that you would have otherwise priced to break even, the software has paid for itself.

Dealers running 30 to 100+ cars per year through floor plan financing encounter this scenario regularly. A car that sat 90 days at a 2% monthly rate on a $15,000 floor plan amount has $900 in interest cost. A car at $20,000 for the same period has $1,200. These are not edge cases — they are normal inventory cycles.

If FoxDMS catches one under-priced deal per year, it has returned 1x to 4x its annual cost. If it catches two, it has paid for the next two years.

Frequently Asked Questions About Floor Plan Tracking Software

What is floor plan tracking in dealer software?
Floor plan tracking automatically calculates the daily interest cost on each floor-planned vehicle based on your floor plan rate. This cost is added to the vehicle's total cost so your profit-per-car is accurate. Without it, dealers often think they made more money than they did — because the floor plan interest was never subtracted from their gross profit.
Does Frazer DMS track floor plan interest?
No. Frazer does not automatically calculate floor plan interest per vehicle per day. Dealers using Frazer with floor plans must add this cost manually or risk understating their true cost per vehicle. This is a significant gap for wholesale operations where floor plan interest directly impacts profit margins on every deal.
Does DealerCenter track floor plan interest?
No. DealerCenter does not offer automatic daily floor plan interest tracking. DealerCenter is built primarily for retail dealers and does not natively track per-vehicle floor plan costs the way FoxDMS does. Dealers using DealerCenter with floor plan financing must calculate and enter this cost manually.
Which DMS automatically tracks floor plan interest?
FoxDMS is the only DMS in this comparison that automatically tracks floor plan interest per vehicle per day. You enter your floor plan rate and the system calculates the daily cost as the vehicle ages in inventory. This cost is built into every deal's profit calculation automatically — no manual entry, no spreadsheets alongside your DMS.
How does floor plan interest affect dealer profit?
The impact is significant and compounds quickly. A $15,000 vehicle on a 2% monthly floor plan rate costs roughly $10 per day in interest. After 90 days that is $900 in floor plan interest that must be subtracted from your profit. Dealers who do not track this often discover deals they thought were profitable were actually break-even or even losses once floor plan costs are accounted for.
What information do I need to set up floor plan tracking?
You need three pieces of information: your floor plan interest rate (monthly or annual), the date each vehicle was acquired (the floor plan start date), and the vehicle's floor plan amount. FoxDMS handles the daily calculation automatically from these inputs — you set the rate once and every vehicle you add is tracked from its purchase date forward.
