Auto Repair Shop Financing: Working Capital for Mechanics & Repair Shops
A lift breaks down on a Tuesday. A diagnostic scanner that costs more than a used car needs replacing before it ever pays for itself. Your parts supplier wants net-15 on a bulk brake-and-rotor order, and the insurance company adjusting a collision claim is still "reviewing the estimate" three weeks after the car left your bay. None of that waits for a bank's six-week underwriting cycle. Auto repair is a cash-intensive, equipment-heavy business running on thin timing margins — and that's exactly the kind of business revenue-based working capital was built for.
Byzfunder is a direct small-business funder — not a bank, not a broker. We review repair shop files and fund from our own balance sheet, with money in as little as 24 hours for qualified files.

The Auto Repair Cash-Flow Problem: Capital-Intensive Work, Slow-Paying Accounts
Repair shops don't have a single cash-flow constraint — they have several stacked on top of each other.
Equipment failure is unplanned and expensive. A two-post lift, an alignment rack, a diagnostic scan tool that keeps pace with modern OBD-II and manufacturer-specific software, an AC recovery machine — this is capital equipment that fails without warning and takes a bay out of service the moment it does. A dead lift isn't a maintenance line item you can defer; it's lost revenue on every job that needs it until it's fixed or replaced.
Parts inventory ties up cash before the job is billed. Shops that stock common parts — brake pads, rotors, filters, fluids, belts — front the cost of inventory before a customer ever pays for the repair. Suppliers extend net-15 or net-30 terms, but a slow month or a run of big-ticket jobs can strain that timing fast, especially for shops carrying parts for multiple makes.
Insurance and fleet-account receivables lag behind the work. Collision and comprehensive-claim repairs get paid by the insurer, not the customer at pickup — and adjuster review, supplement approvals, and claim disputes routinely stretch payment 30–60 days past completion. Fleet accounts (delivery companies, rental agencies, local government contracts) often run on net-30 or net-45 invoicing too. The labor and parts are already spent; the cash isn't in yet.
Seasonality and tech staffing add pressure on both ends. Many shops see swings around extreme-weather seasons (AC season, winter tire and battery season) and lulls in between. Meanwhile, keeping ASE-certified techs on payroll — and covering signing incentives or overtime during peak season — is a fixed cost that doesn't flex with a slow month.
Growth means a bay before it means revenue. Adding a bay, opening a second location, or buying out a competing shop requires capital up front, before the additional throughput shows up in deposits.
How MCA and ByzFlex Work for Auto Repair Shops
Merchant Cash Advance (MCA) / Term Loan
An MCA is an advance against your shop's future revenue. Byzfunder purchases a portion of your future receivables at a fixed factor rate, and repayment is collected via daily or weekly draws tied to your deposit activity — not a fixed loan payment, and not an APR. Slower weeks mean smaller pulls.
Best fit for repair shops when:
- A lift, alignment rack, or diagnostic tool needs to be replaced now, not after a bank approval.
- You're stocking up on parts inventory ahead of a known busy season.
- You're opening a bay, adding a location, or buying equipment for a new service line (like EV diagnostics or ADAS calibration).
Advance amounts: $5,000–$500,000. Terms: 3–15 months. FICO floor: 525. Revenue requirement: $20,000+/month in business deposits. Time in business: 1 year minimum.
ByzFlex — Revenue-Based Revolving Capital
ByzFlex is revenue-based revolving capital — draw what you need, repay weekly, and draw again every 14 days up to your approved limit as your revenue supports it. It is not a line of credit; it's a revolving facility structured around your deposit performance.
Best fit for repair shops when:
- Insurance or fleet-account payment timing creates a recurring gap between work completed and cash received, and you want a revolving buffer rather than a single advance.
- You run multiple bays or locations and want ongoing access to capital rather than one lump sum.
- Annual revenue is $250,000+ and you can support weekly repayment from shop deposits.
Available amounts: $7,500–$150,000. Repayment: weekly. FICO floor: 550. Revenue requirement: $250,000+/year.
A single shop is offered MCA or ByzFlex — not both simultaneously.
Comparing Your Options
| Option | Speed | Cost Basis | Best For | Credit Floor |
|---|---|---|---|---|
| MCA (Byzfunder) | As little as 24 hrs | Fixed factor rate on advance | Urgent equipment replacement, parts stocking, expansion | 525 |
| ByzFlex (Byzfunder) | As little as 24 hrs | Revenue-based, revolving draw fee | Recurring insurance/fleet-payment gaps | 550 |
| Bank term loan | Weeks to months | Interest rate (APR) | Large, planned equipment purchases with strong financials | Typically 680+ |
| SBA loan | Months | Interest rate (APR) + fees | Long-term expansion, real estate, major buildouts | Typically 650+ |
| Equipment financing | Days to weeks | Interest rate or lease rate, secured by the equipment | Financing a single, identifiable piece of equipment | Varies by lender |
Bank term loans and SBA loans can offer lower cost of capital for shops with strong financials, established time in business, and the patience for a longer approval process. Equipment financing is worth comparing when the need is a single identifiable asset (a lift, a scan tool) rather than general working capital — it's typically secured by the equipment itself, which can mean better terms but also means the lender has a claim on that asset. Byzfunder's MCA and ByzFlex are built for shops that need capital fast and can't wait out a multi-week bank cycle, or that don't yet have the credit profile a bank or SBA loan requires.

What Byzfunder Looks at for Repair Shop Files
Business bank account deposits. We underwrite on what actually hits your business checking account — not gross work-order totals or outstanding insurance claims. For shops with heavy insurance or fleet business, your deposit history shows the real payment cadence, and that's what we read.
Deposit consistency. A general repair shop, tire and brake specialist, or collision shop with steady monthly deposits over 3–6 months is a fundable profile. Seasonal variation is normal — the underwriting looks for an ongoing operating pattern, not a perfectly flat line.
Time in business. Minimum 1 year. A shop that's made it past its first year has an established customer base, supplier relationships, and a deposit history to underwrite against.
FICO floor. 525 for MCA/Term Loan, 550 for ByzFlex. Score above the floor means your file moves to full underwriting review.

Frequently Asked Questions
We do a lot of insurance/collision work and get paid by the carrier, not the customer. Does that count as business revenue?
Yes. Insurance payments that hit your business bank account count as deposits the same as any other customer payment. If your deposits show a consistent pattern even with claim-payment delays factored in, that's what we underwrite against.
We have outstanding invoices to a fleet account that hasn't paid yet. Does that receivable matter?
We underwrite on deposited cash, not on outstanding invoices or accounts receivable. Unpaid fleet or insurance invoices are future revenue — useful context — but not the basis for the advance. Your recent deposit history is what carries the file.
Can financing be sized specifically to buy a new lift or diagnostic scanner?
Advance amounts are based on your revenue and file strength, not a specific invoice or purchase price. If your file supports the amount you need, you can use the funds toward that equipment purchase. We provide working capital, not equipment-specific financing.
I run a one-bay independent shop under my own name. Do I qualify?
You'll need to apply through a registered business entity (LLC, S-Corp, or equivalent) with its own business bank account — not as an individual. Beyond that, sole-operator shops qualify on the same criteria as larger operations: deposit consistency, time in business, and FICO floor.
We had a slow stretch when a key tech left and we were short-staffed for two months. Will that hurt the application?
Context matters. A documented, temporary dip tied to a specific cause — like being short a technician — reads differently than a sustained decline. If your deposits have recovered in recent months, that recovery is visible in your statements. You're welcome to include context in your application.
Do you finance the equipment directly, like a lease?
No. Byzfunder provides working capital — an advance (MCA) or revolving capital (ByzFlex) based on your business's revenue. You decide how to use the funds, including toward equipment, but we're not structuring a secured equipment lease.
