How to Offer Repair Financing at Your Auto Shop

Your own IOU or an outside lender. Pick the lender. Offer financing through a company that pays you and carries the risk. Put the monthly number on the estimate next to the total. Push true zero percent plans over deferred interest. And keep the car until the lender's money is approved. The need is real. In the Federal Reserve's 2025 household survey, only 63 percent of adults said they'd cover a $400 emergency with cash. Car repair or replacement was the most common big surprise bill, hitting 30 percent of adults (Federal Reserve, May 2026).

1. More than a third of adults wouldn't cover a $400 bill with cash. A $1,500 repair is a much bigger ask.
2. An outside lender pays the shop and takes the default risk. An in house plan leaves both with you.
3. Deferred interest can bill months of back interest at the end. Customers with low scores dodge it only about half the time.
4. If you send customers to a lender, the loan must carry the FTC Holder notice. A bad repair becomes the lender's problem too.
5. In California your repair lien depends on keeping the car. Don't release it on a promise.

Why So Many Customers Can't Pay Today

The Fed asks the same question every year. Could you cover a $400 surprise with cash or its equivalent? In the survey run in October 2025, 63 percent said yes. That share hasn't moved in three years, and it's down from 68 percent in 2021 (Federal Reserve).

It gets tighter lower down. Among adults earning under $50,000, 4 in 10 said they couldn't cover even a $100 surprise from savings. And 16 percent of all adults didn't pay every bill the month before (Federal Reserve).

Now picture your counter. Your average customer isn't broke. But a timing chain, a transmission or a head job lands on a Tuesday, and the money for it lands on Friday, or next month. Without a way to split it, the car sits, or it leaves on a tow truck to someone cheaper.

Customers already know to ask. Credit Karma's repair financing guide tells drivers to ask if the shop offers financing, and names shop cards from chains like Midas and Firestone (Credit Karma). If the chain down the street has an answer and you don't, you lose the job on the phone.

Three Ways a Shop Can Offer It

There are only three real setups. They differ in who gets paid first and who eats it when a customer stops paying.

A summary for planning, not legal advice. Read the merchant agreement and check your state's rules before you sign up.

Synchrony, which runs a car care card, says shop applications are usually done at the counter, with approvals often given right away (Synchrony, April 2025). That speed is the point. The customer decides while they're still standing there.

Ask any lender three things before you sign. What does each sale cost the shop? How fast does the money reach your account? And what happens to you if the customer disputes the repair? Get all three answers in writing.

Zero Percent Isn't Always Zero

Two promos sound the same and work nothing alike. A true zero percent plan charges no interest during the promo. Interest starts only on what's left after it ends. A deferred interest plan adds up interest from day one and bills all of it if the balance isn't paid off in time.

The CFPB looked hard at this. In June 2017 its director said deferred interest promos may surprise people with high back interest after the promo ends. Customers with low credit scores avoided that charge only about half the time. Customers with high scores avoided it nearly 90 percent of the time (CFPB, June 8, 2017). The Bureau urged card companies to use true zero percent promos instead.

Think about who finances a repair. It's often the customer with the thinnest cushion. Sell that person a deferred plan and there's a fair chance they get a big interest bill in month thirteen. They won't blame the bank. They'll blame the shop that wrote the estimate.

So when a lender offers both, lead with the true zero percent plan, even on a shorter term. A worked example. A $3,000 repair over 12 months at zero percent is $250 a month. Say that number. Then say plainly what happens if it isn't paid off by month twelve.

The Lender Rules That Land on Your Shop

Two federal rules matter most. The first is the FTC Holder Rule. It covers a loan used to buy goods or services when the seller refers customers to the lender, or has a contract or business deal with it (16 CFR 433.1). Services count, so repairs count.

In that case it's unfair for the seller to take the loan money unless the contract carries the Holder notice. The notice says whoever holds the loan is subject to the claims and defenses the customer could raise against the seller. Recovery is capped at what the customer has paid (16 CFR 433.2). In plain words, a botched repair can follow the loan. Good lenders know this, which is why they watch shops with lots of disputes.

The second is Truth in Lending. Under Regulation Z, you're a creditor if you regularly extend consumer credit that has a finance charge or is paid by written agreement in more than four installments. Regularly means more than 25 times in the past calendar year (12 CFR 1026.2).

That draws a clear line for an in house plan. Split a bill into four payments or fewer, with no fee, and you stay outside that definition. Add a fee, or a fifth payment, and do it more than 25 times a year, and you're a creditor with disclosures to make. State lending laws can add more. Most shops are better off letting a lender do the lending.

Keep the Car Until the Money Clears

In California, anyone who repairs a car has a lien dependent upon possession for what they're legally owed (Civil Code 3068). The lien and the keys go together. Hand the car back on a handshake plan and the hold that makes the lien work leaves with it. We walk through the full lien process in our California mechanic's lien guide.

• Release the car when the lender's approval is in hand and the funding is confirmed, not when the customer says they applied.
• On an in house plan, take a real first payment before the keys go back.
• Put the payment method on the invoice, so nobody argues later about what was agreed.
• Keep the signed estimate and the approval with the job. The lender may ask for it.

Put the Monthly Number on the Estimate

Financing works best as a line on the estimate, not a speech at the end. In California the estimate already has to show the job and the price for parts and labor before work starts (BAR Write It Right, updated January 2026). Add one more line under the total with the monthly option.

Then say it the same way every time. Something like this, with your own lender's terms in it. The numbers are a worked example.

• The total is $3,000, parts and labor.
• If it's easier, there's a 12 month plan at zero percent. That's $250 a month.
• It takes about five minutes to apply on your phone. You'll know right away.
• If it isn't paid off by month twelve, the plan's regular rate kicks in on what's left.
• Want me to send the link while we finish the parts order?

Say it to everyone, not just the customer who looks worried. Picking who hears it is how you insult a good customer and miss the one who needed it.
