Dealer Financing Is Hiding Your Real Install Margin

A customer signs for a $12,000 system on a 0% promotional plan. You invoice $12,000. A few days later the lender funds your account — and the deposit is $11,040.

That $960 is a dealer fee, and where it lands in your books determines whether you ever find out what financed work actually returns. In most shops I have looked at, it lands in a general expense account, gets forgotten, and quietly inflates the margin on every financed job in the system.

What a dealer fee actually is

When you offer point-of-sale financing, the lender pays you the job amount less a percentage. The customer owes the lender the full amount; the discount comes out of your side.

Mechanically it works like a credit card processing fee. The difference is size. Card processing runs a couple of percent. Dealer fees on consumer financing are typically several times that, and the structure has a specific shape worth understanding:

• Short-term or interest-bearing plans carry lower fees. The lender makes money from the customer's interest.
• Long promotional 0% plans carry the highest fees. The customer pays no interest, so somebody funds that — and it is you, up front, through the fee.

That inversion matters, because the plans that close the best are usually the ones that cost you the most. A twelve-month 0% offer is easy to sell precisely because it is expensive to provide.

Get your actual numbers from your dealer agreement. They differ by lender, by plan, by term, and by your own volume tier. Any percentage quoted in an article, including this one, is a shape rather than your number. What matters is that you know the fee on each plan you offer — and most shops I ask cannot say without looking it up, which is itself the problem.

Why this distorts your margins specifically

Say your install pricing assumes 35% gross margin. A $12,000 system:

Eight points. On one job.

Now consider what that does at scale. If half your installs are financed, and your reporting says installs run 35% when the financed half actually returns 27%, then:

• Your blended install margin is overstated, so you think the install side of the business is healthier than it is.
• Your pricing is built on the wrong number. Next season's prices are set from a margin you never earned.
• Your plan mix is invisible. The 0% offer your salespeople push hardest may be your least profitable, and nothing in your reporting will say so.
• Cash jobs and financed jobs look identical. They are not.

The insidious part is that nothing looks broken. The books reconcile. The bank matches. The fee is recorded — just in the wrong place, where it cannot be attributed to the work that caused it.

How to record it correctly

The principle: the fee is a cost of the job that generated it. It belongs in cost of goods sold, tagged to that job, not in a general operating expense account.

The mechanics, in the order they happen:

1. Invoice the customer for the full amount. $12,000. That is the revenue you earned and what the customer owes.
2. Record revenue at $12,000, not at the funded amount. Netting the fee against revenue is the other common error — it makes the fee disappear entirely and understates your top line.
3. When the lender funds, record the deposit at $11,040 and post the $960 difference to a Financing dealer fees COGS account, tagged to that job.
4. Reconcile the funding batch the same way you would a card processor batch. Lenders often fund several jobs together, so the deposit will not match a single invoice.

Two things fall out of this immediately. Your job costing now includes the fee, so per-job margin is real. And you have an account whose balance tells you exactly what financing cost you last quarter, which is a number most shops have never seen.

If you want the surrounding structure, the HVAC chart of accounts and electrical chart of accounts both include the account this belongs in.

The mistakes I see most

Netting the fee against revenue. Recording $11,040 of revenue makes the cost invisible and understates your revenue for every other purpose — benchmarking, valuation, lender conversations. Gross revenue, then the fee as a cost.

One "Merchant & bank fees" account for everything. Card processing and financing dealer fees get combined, and neither can be analyzed. Card fees are a roughly fixed cost of doing business. Financing fees vary by plan and are a pricing lever. Separate accounts.

Recording it at month-end as a lump sum. Someone reconciles the lender statement and books one entry for the month's fees. The total is right and every job is still wrong, because nothing is tagged.

Ignoring it because "it is only a few percent." On a business doing $600,000 of financed installs, even a mid-single-digit fee is tens of thousands of dollars a year sitting in an account nobody reviews.

What to do with the number once you have it

This is the part that pays for the work. After a quarter of costing fees to jobs, you can ask questions that were previously unanswerable:

Is financed work still worth it? Almost always yes. Financing closes jobs that would otherwise not close and tends to raise average ticket — a customer choosing between a base unit and a better one frequently upgrades when it is a monthly payment. Those effects usually outweigh the fee comfortably. But now you know that rather than assuming it.

Which plans should you actually promote? If the 24-month 0% plan costs three times the 12-month plan, and both close at similar rates, you have a straightforward decision that was previously invisible.

Should financed work be priced differently? Some shops build the fee into pricing on financed jobs. Whether that is right for your market is a judgment call — but it is a judgment you cannot make without the number.

What is your real install margin? The blended one, with financed and cash work costed honestly. That is the number your pricing should be built on.

The bigger pattern

Dealer fees are one instance of a general problem in trade bookkeeping: costs that are real, attributable, and routinely recorded in the wrong place. The same thing happens with permits and inspections, callback labor, and technician hours that never get allocated to the jobs they were spent on.

Each one individually looks small. Together they are the difference between a job costing system that guides pricing and one that produces numbers nobody trusts. The test is simple: if a cost was caused by a specific job, it belongs on that job.
