Best revenue-based financing for auto repair shops

The best revenue-based financing for an auto repair shop is repaid from a share of your sales, so the payment eases off when fewer cars come through the door. Merchant Fund Express, our recommended funder, tops the list: it reviews your sales and deposits, considers credit from FICO 500, accepts ITIN applicants and often decides in 2 to 4 hours. If you're buying a lift or an alignment machine, equipment financing usually costs less; if you have a solid track record, a line of credit is cheaper for buying parts.

Below you'll find the options in order, how the payment works on each one, a criteria table and the mistakes that make shop financing more expensive than it needs to be. Leer en español.

The best revenue-based options for auto repair shops, ranked

How we chose. We don't use ratings or scores. We compared each option on the same criteria: speed, minimum time in business, minimum credit, whether it accepts an ITIN or owners without an SSN, documents, amounts and collateral. We only publish facts about other companies if we verified them on their official site. Read how we rank business funding options.

1. Merchant Fund Express (recommended funder). It reviews your sales and deposits, not just your credit, with amounts from $5,000 to $5,000,000 and credit from FICO 500. Decisions often come in 2 to 4 hours, collateral isn't required in most cases, and applying is free with no impact to your credit. It accepts applicants with an ITIN (no SSN needed) and offers Spanish-speaking support, so you can ask every question in the language you prefer.
2. Payment as a percentage of monthly revenue. You pay a percentage of what comes in each month until you reach the agreed amount. When the slow season hits, the payment drops. This is the option that best protects a shop with very uneven months.
3. Card-holdback advance. The funder collects a percentage of every card sale, day by day. It fits counter-heavy shops with lots of terminal volume, like oil change, tire or quick-service shops.
4. Equipment financing. For buying lifts, alignment machines, tire changers, diagnostic scan tools, or chargers and tools for electric vehicles. The equipment secures the loan and the payment is fixed. It isn't revenue-based, but for equipment that lasts many years it usually costs less.
5. Shop line of credit. A cushion for buying parts and covering payroll while fleets or insurers pay you. Banks usually ask for a track record, tax returns and good credit.
6. SBA microloan or CDFI. The SBA says its microloans go up to $50,000 with terms of up to seven years, made through nonprofit organizations. They usually cost less and come with coaching, but they take weeks.

How money really moves through a repair shop

A repair shop has a cash cycle that few funders understand at first glance. Explain it well and it will help you get a better offer:

• Parts get paid for first. You buy the transmission or the brake kit and collect when the customer picks up the car. On big jobs, that can be days later.
• Fleets and insurers pay late. If you service company vehicles or handle insurance claims in collision work, you may wait weeks to get paid.
• Seasons. Winter brings batteries and brakes; summer brings A/C and tires. Between seasons, fewer cars come in.
• Techs and tools. A good technician is expensive, and diagnostic subscriptions and equipment for newer models keep going up.

A payment calculated as a percentage of your sales breathes with that rhythm. A fixed daily payment, on the other hand, leaves your account even on a day when you didn't hand back a single car. That's the core reason revenue-based financing appeals to shops: it's built around the way repair revenue actually arrives, not around a calendar.

Which option fits your kind of shop

Quick-service or tire shop

Lots of small tickets, almost all paid by card. A holdback advance or financing based on your deposits fits well, as long as the percentage doesn't eat your margin on slow days.

General repair shop with big jobs

You buy expensive parts and collect on delivery. A payment based on a percentage of monthly revenue, or a line of credit if you qualify, gives you breathing room without daily debits. Compare it with a business line of credit for auto repair.

Body and paint shop with insurance claims

Your cash depends on when insurers pay. Show your open claims and how old they are: it helps the funder understand why your deposits arrive in chunks.

A shop growing with new equipment

If you're adding a lift or EV service equipment, use equipment financing for the purchase and keep revenue-based capital for operations. Compare options in equipment financing for auto repair.

How to tell whether the payment fits your shop

Before you accept any offer, run this simple test with your own numbers. You don't need a financial calculator, just your bank statements:

1. Find your worst month of the past year. It's usually the one after a strong season, when fewer cars come in.
2. Subtract that month's fixed costs: rent, tech payroll, insurance, utilities, diagnostic subscriptions and any current debt payments.
3. Compare what's left with the new payment. If the payment eats nearly all of it, the amount is too high or the term too short.
4. Ask how it adjusts. If the payment is a true percentage of your sales, it drops on its own in that slow month. If it's fixed, it won't.
5. Keep a cushion for parts. A shop with no cash for parts loses jobs, and that makes any financing harder to repay.

If the test shows the payment doesn't fit, ask for a smaller amount or combine tools: part of the need with equipment financing and part with working capital.

Documents funders usually ask for

• Business bank statements for the last 3 to 6 months, complete and in PDF.
• Sales reports from your card processor or your repair order system.
• A list of fleet or insurance receivables, if you have them.
• Your shop lease and any licenses your city or state requires.
• Owner ID, EIN and your LLC or corporation documents.
• Details on any active financing, with balance and payment.
• An equipment quote, if the money is for a machine.

A practical tip: if some customers pay cash, deposit all of it in the business account. What doesn't get deposited doesn't count when a funder works out how much it can offer you.

Mistakes that make shop financing more expensive

• Paying for ten-year equipment with months-long capital. The short payment squeezes your cash flow for no reason.
• Stacking advances. Two holdbacks on the same card sales can leave you with no money for parts.
• Borrowing more than you need. A bigger amount means a bigger payment or more time paying.
• Not asking how the payment is calculated. Make sure you know whether it's a percentage or a fixed amount, and how it adjusts in a slow month.
• Paying fees upfront to “unlock” an approval. That's a classic sign of fraud.
• Signing something you don't fully understand. Ask for the contract to be explained, in Spanish if that's easier for you.

If your shop already has steady sales, you can apply with Merchant Fund Express; it's free and doesn't affect your credit. To compare across industries, see our best small business funding rankings.
