Every shop that signs up for a car repair payment plan gets the same welcome kit: a window decal, a counter card, and a stack of brochures that will still be shrink-wrapped at Christmas. Four months later the decal has outsold every advisor on the floor. It faces the parking lot. It never loses its nerve.
Here is what actually happened. One advisor tried it once, said the words in the same apologetic voice he uses for the diagnostic fee, the customer said no, and the program quietly became wall art.
That matters, because these products cost you nothing until somebody uses one. Which is exactly why so many shops have one and so few can tell you what it costs.
So this is the part nobody on this topic publishes. What these plans are, who pays for them, what the fee does to a ticket, and where it belongs in your numbers. Written for the owner and the multi-store operator, not the customer at your counter.
Yes, financing turns a no into a yes. We said that already in the piece on what belongs on an auto repair invoice, and I am granting it in one sentence so the rest of the page can be about the part that costs money.
Yes, auto repair shops do payment plans, and the money is almost never theirs
If you searched some version of “do auto repair shops do payment plans,” here is the whole answer in three sentences.
A third-party provider approves the customer, usually in a couple of minutes on their phone. The provider pays your shop, less a fee. The customer then owes the provider, not you.
You are a merchant in that deal, not a lender. You do not own the balance and you do not chase the payments, and in most standard agreements you do not eat the loss if the customer stops paying. Most, not all, which is why the agreement is worth twenty minutes of your Sunday.
So if you are working out how to offer financing to customers, the order is boring: pick one provider, read the rate, then teach one advisor one sentence and let the rest hear it work.
The four kinds of car repair payment plan, and they do not cost the same
Nobody selling these draws the map, so here it is.
1. Point-of-sale installment financing. The customer applies at the counter or from the waiting room, picks a term, and the provider funds you. Your cost is a per-transaction fee. This is the one category where a vendor publishes its number.
2. Branded revolving credit used in service. A card the customer keeps, often with a promotional interest period above some purchase threshold. Your cost is typically a merchant discount rate, and longer promotional terms usually cost the merchant more. The rate lives in your agreement, not in a blog post.
3. Lease-to-own and second-look products. Built for thin or no credit. These get their own section below, and not a recommendation.
4. You carry it yourself. Also its own section, because my answer is no and I want to show my work.
Two of these sit inside your payments stack as a software decision. If that is your actual question, the payments and financing layer of the shop software stack has the shortlist. This page is about the economics.
”No credit check” is a product category, not a favor
Somebody types “car repair payment plan no credit check” at nine at night with a car that will not start in the morning. Two product families answer that search, and both are worth understanding before an advisor offers one as a kindness.
A second-look program is a secondary lender that reviews applications the primary lender declined. Approval gets easier. The price goes up. That is the entire mechanism.
Lease-to-own is not a loan. The finance company buys the goods and leases them to the customer with an option to purchase. Because it is a lease rather than credit, it is often disclosed and regulated differently, and the total of payments required to own can run well above the cash price of the repair. Many include an early purchase option that costs far less, which is the most valuable thing a customer can be told.
I am not going to rank these or point you at one. If one of them is in your shop:
- Give the customer the total of payments, in writing, not the monthly payment. The payment is a feeling. The total is a number.
- Know whether your shop is named anywhere in that contract and what you owe if the deal unwinds.
- Do not let an advisor “get somebody approved” as a personal favor. A favor that ends with a customer paying double for a water pump comes back as a review you will read out loud to your spouse.
And the unpopular version. If the only way a customer can afford the job is a product that costs them close to double, sometimes the right recommendation is the smaller repair. That is not lost revenue. That is a customer who comes back.
What customer financing actually costs your shop
Search this topic and the top of the page is a wall of merchant pages selling financing. Not one publishes what it costs you in a form you can compare.
One publishes a number. On its own automotive merchant page, Wisetack states: “You simply pay a 3.9% per transaction fee when a customer completes financing through Wisetack.” The same page says the funds arrive by bank transfer and “will land in your account within 1-3 business days,” on financing “available from $500 - $15,000 on terms from 3 to 12 months.”
Whatever you think of the rate, that is a shop owner being told the price before signing.
Now the more interesting finding, which is an absence. Sunbit’s auto merchant page publishes no merchant fee, no subscription cost, and no merchant discount rate. It is not a thin page either. It publishes “>96% of customers approved,” a purchase range of “$60-$10,000,” terms of “3, 6, and 12 months,” and an “Annual percentage rate (APR) 0-35.99%” with state-specific caps.
So the page is full of numbers. Every one of them describes the customer’s side of the deal. (I checked twice, then checked whether I had landed on the consumer page by mistake. I had not.)
I tried Synchrony’s automotive merchant page for the same comparison. It would not load for us, so I am not going to tell you what is on it.
And I am not printing the merchant percentages that circulate for these providers in roundups and reposted help-center articles. I could not open one page from the vendor that carries them. If I cannot open the page, I cannot print the number, and neither should the article that quoted it.
Which leaves the only rate that has ever bound anybody: the one in your signed agreement. Read three things. The per-transaction rate. Whether longer promotional terms cost more than the headline one. And the funding timeline, because “we pay you up front” and “we pay you in three business days” are different sentences.
A 3.9% fee against a 9.6% net margin
Here is the arithmetic no merchant page will run for you. All illustrative, all worth redoing on your own numbers.
Take a $2,000 repair. That is roughly three average repair orders: per accounting firm Paar Melis’s 2025 benchmark report, built from client shops’ actual 2024 financials, the average repair order runs about $702. This is a real ticket, the kind that gets declined.
At a published 3.9% per-transaction fee, that job costs you $78 you do not receive.
Now set it against net profit instead of revenue, because 3.9% of a ticket is not 3.9% of anything you keep. In the same Paar Melis benchmark, average net profit runs about 9.6% of sales. On $2,000 that is roughly $192 of net for the whole repair order.
So the fee eats something like 40% of the net on that job.
That makes people angry at financing, which is wrong twice over. The fee only exists when a customer uses the plan, so an unused program costs you nothing but wall space. And on this kind of ticket the alternative is usually not a cash sale. It is a declined job and a car that leaves with the noise still in it. $192 minus $78 is $114. Zero minus nothing is zero.
The useful conclusion is narrower: the ticket cannot absorb both a fee and a discount. Do both to the same repair order and you have turned a profitable job into a favor.
Financing beats discounting, and the arithmetic is not close
Same $2,000 job. Two ways to get to yes.
Finance it and it costs $78, once, on a full-price ticket you keep the rest of.
Discount it and a 10% “let me see what I can do for you” is $200 gone. Unlike the fee, it never comes back to gross profit, it resets what this customer believes your price is, and it travels to their next visit and their brother-in-law’s.
Nearly three times the cost, plus a habit. The per-percentage-point arithmetic across a whole shop is already worked out in what service advisor discounting costs your parts gross profit. I am only noting which lever is cheaper, because most shops reach for the expensive one first.
Should you carry the paper in-house? Almost certainly not
Carry a balance as a matter of policy and you have started a second business you never applied for: a finance company with one customer, no underwriting, and no collections department.
You own the receivable. You own the calls at day 30, day 60, and the one at day 90 where the number is disconnected. You own the write-off. And you own a body of consumer-credit rules written for lenders, which vary by state and were not drafted with a five-bay shop in mind.
You also fund the repair yourself. That is where the working capital question actually lives, and it is simple: parts invoices and payroll go out before collections come in. An in-house plan widens that gap on purpose. You paid the parts vendor on the 10th so the customer could pay you in November.
The shop-side answer to a customer who cannot pay is not patience. It is possession and paperwork. Your security sits in the fact that the car is on your property, and how a mechanic’s lien on a car actually works is worth reading before you hand keys over on a promise.
One caveat, because I grew up in a shop. Everybody has taken a $300 check in two pieces for a customer they have known eleven years. That is a judgment call. It stops being one the second it has a name, a form, and a spot on your website.
And plainly: in-house financing touches state consumer-lending and disclosure law. This is operator experience, not legal advice. Before it becomes policy, that is a conversation with your attorney and your accountant, not with me.
Where a car repair payment plan fee should show up in your numbers
The merchant fee is a cost of sale. It is not a marketing expense, and it is definitely not “bank charges.”
“Bank charges” is the junk drawer of the chart of accounts. Everything goes in and nothing comes out. Bury financing fees in there with your card processing and you cannot answer the two questions that matter: what share of tickets got financed, and what those tickets cost you.
Three fixes, none of which require software:
- Give financing fees their own account or sub-account, separate from card processing.
- Report three numbers a month, per store. Financed ticket count, financed dollars, fee dollars.
- Do not code the fee against parts. It distorts parts gross profit, which Paar Melis puts at about 46.1% on average, and that is the number you use to check whether your parts and labor margins are where you set them.
Then the honest limit. Financing fixes one side of your cash flow, the money coming in, and on Wisetack’s published timeline that side moves in one to three business days. It does nothing about the money going out.
Which is where I should be straight about my own product. WickedFile sits on the payables side. It reconciles parts invoices and vendor statements against your shop management system so you can see what you bought, what got billed to a customer, and which credits never showed up. It does not finance anything, approve anyone, or collect a dollar. A customer who cannot pay today is a lender’s problem. Not knowing whether the $78 fee or the uncredited return did more damage last month is ours.
Group-level financing is a contract question, not a counter question
If you run more than one store, this decision is not made at the counter. It is made once, in a contract, and then it is measured.
Five stores signing five agreements gives you five different effective discounts on the same work, and none of them are visible on a consolidated P&L. Everybody codes the fee somewhere different, so the number never adds up to anything comparable.
The group version is four decisions:
- One provider, one negotiated rate, for the whole group.
- One GL code, used identically at every store.
- One report, monthly, per store: share of tickets financed, average financed ticket, fee dollars.
- One rule about which products may be offered in your buildings, so no store quietly adds a lease-to-own vendor because a rep bought lunch.
That third one is where the coaching hides. If store three finances 22% of its tickets and store one finances 3%, that is not a market difference. That is one advisor who can say the sentence without flinching and four who cannot, and it lands where every other number lands: the profit picture built one repair order at a time.
The one thing to do this week
Pull three months of statements. Put every financing fee you paid in one column and every discount your advisors gave in the column next to it.
One of those columns bought you a repair order at full price. The other bought you a habit.
And if the decal on your door is still your best closer, the least you could do is put it on the pay plan.
