Auto Payment Processing

Auto repair shops, dealerships, body shops, and service centers all need the same thing from their auto merchant services provider: high ticket sizes, high card usage, and processing fees that quietly eat into every job. A $900 brake job at 2.9% flat rate costs $26.10 in processing. At interchange-plus, that same transaction often runs $12–$14. Multiply that across a month of service tickets and the difference is real money.

Auto payment processing through Brookside Payments means a dedicated merchant account — not a PayFac aggregator that can freeze your deposits without warning — with transparent interchange-plus pricing and a local representative who picks up the phone.

We work with the full range of automotive businesses:

• Auto repair shops — high-ticket transactions, mixed card types, frequent commercial cards from fleet accounts
• Car dealerships — large down payments, service department processing, parts sales, F&I transactions
• Body shops and collision centers — insurance-adjacent billing, large repair invoices
• Tire and brake shops — volume-driven, price-sensitive, high card usage
• Auto detailing and car wash — recurring and membership billing, contactless and mobile payments
• Parts suppliers and wholesalers — B2B transactions, commercial cards, Level 2/3 processing for reduced interchange
• Towing and roadside services — mobile card acceptance, field payments

If your business touches the automotive industry and accepts card payments, we can structure a merchant account around how you actually operate — not a one-size-fits-all flat rate built for someone else’s volume.

The Flat-Rate Problem for Auto Shops

Flat-rate processors — Square, Stripe, PayPal — charge the same percentage regardless of card type. For automotive businesses, that’s a problem. Auto shops process a disproportionate share of commercial fleet cards, rewards cards, and corporate cards, all of which carry higher interchange rates. When you’re on a flat rate, you pay the same whether the card costs 2.0% or 2.8% to process — the processor pockets the difference.

With interchange-plus pricing, you pay the actual interchange cost plus a fixed markup. Every card type is priced at cost. A debit card costs less than a rewards card, which costs less than a corporate card — and you see exactly what each one costs on your statement. According to the Federal Reserve’s interchange fee data, average interchange varies significantly by card type — flat-rate pricing hides that variation and captures it as margin.

For high-ticket automotive transactions, the savings on interchange-plus versus flat-rate are typically 0.5–2.0% per transaction. On a shop processing $80,000 a month, that’s $400–$800 in monthly savings.

Cash Discount & Dual Pricing for Auto Shops

Many auto shops have moved to a cash discount program or dual pricing — posting a card price and a lower cash price side by side. Customers who pay cash get a discount; customers who pay by card pay the posted price. The math works cleanly in automotive: repair invoices are itemized line by line, which makes the pricing structure transparent and easy to explain at the service desk.

When implemented correctly, these programs are fully compliant with card network rules and CFPB consumer disclosure requirements. We handle the setup, the terminal configuration, and the compliance documentation — so your service advisors aren’t guessing at the counter.

Auto shops aren’t office environments. Terminals get moved, counters get greasy, and service advisors need to process payments quickly between customers. We equip automotive businesses with hardware built for the environment:

• Countertop terminals — fast, durable, EMV chip and contactless NFC for tap-to-pay
• Wireless terminals — for shops where the service desk isn’t fixed, or for pull-around and drive-through service lanes
• Mobile card readers — for towing, roadside, and field service businesses
• Virtual terminal — take card payments over the phone for remote approvals, deposits, and parts orders via virtual terminal

All automotive payment processing equipment integrates with your existing point-of-sale or shop management software. If you’re running a DMS or shop management system, ask us about integration options before assuming compatibility is a barrier.

PayFac platforms like Square and Stripe are designed for simplicity and scale — millions of merchants, automated risk management, no underwriting. That model works until it doesn’t. A volume spike before a big weekend sale, a chargeback from a disputed repair, or a large single transaction can trigger an automated hold with no warning and no one to call.

Brookside Payments provides automotive merchant services built around a dedicated merchant account — your business underwritten individually. Your processing history, your ticket sizes, your industry — all known from day one. Holds are rare because surprises are rare. And when something does come up, you call a person, not a chatbot.

We serve automotive businesses in Nashville, TN and Boca Raton, FL — and surrounding markets. If you’re processing more than $10,000 a month and still on a flat-rate platform, a free statement review will show you exactly what the difference looks like at your volume.
