When a F&I manager spends significant time securing lender approval, structuring terms, discussing F&I products, and preparing documents, the deal is on the one-yard line.
Roughly 80% of vehicle buyers arrange their financing directly through the dealership, making F&I one of the store's primary profit drivers—often generating 25% to 35% of overall dealership gross profit through finance markups and secondary products.
Then comes another important step: collecting the down payment.
On a typical $50,000 new vehicle, a standard 20% down payment totals $10,000. How the dealership accepts that payment has a major impact on the economics of the transaction. A 3% processing fee on that $10,000 payment creates a $300 transaction expense. The dealership must then make a choice: absorb that $300 cost directly out of the sale's profit or pass it on to the customer through a credit card surcharge.
To protect profitability while giving customers convenient ways to pay, dealerships should consider the cost and payment risk behind each option.
Dealership Profitability Varies by Department
A factory franchise dealership operates several distinct businesses under one roof, and the financial margins vary considerably by department:
- Parts and Service (Fixed Ops): Fixed Operations generates some of the dealership's strongest gross margins, routinely averaging 40% to 60%+ and potentially higher on labor. Even with stronger margins, payment acceptance costs still affect profitability on high-dollar repairs. Offering guaranteed ACH and check options alongside cards gives dealerships additional ways to manage those costs.
- Used Vehicle Sales: Used vehicles generally produce front-end gross margins of 8% to 12% ($2,000–$3,000 per unit), giving dealerships slightly more flexibility when evaluating payment acceptance costs.
- New Vehicle Sales: New vehicle sales operate on razor-thin front-end gross margins, typically between 3% and 6%. When a down payment reaches several thousand dollars, a 3% credit card fee can take a meaningful amount out of the transaction.
The economics differ, but payment acceptance costs matter throughout the dealership. Giving customers multiple ways to pay helps manage those costs rather than defaulting to a single payment method.
The Math Behind a Large Down Payment
The impact becomes clearer when you look at the actual numbers.
On a $10,000 down payment, a 3% credit card processing fee represents $300. If the dealership absorbs it, $300 comes directly out of the economics of the sale. If the dealership imposes a compliant surcharge, the customer could instead face an additional $300 charge for using the card.
Either way, a percentage-based fee becomes significant on a high-dollar transaction—particularly when new-vehicle front-end margins are relatively narrow.
The customer may see an opportunity to earn credit card points. The dealership must look at the transaction from two perspectives: What is the most cost-effective way to collect this payment, and what happens if there's a problem with it later?
Payment Risk Doesn't End When the Vehicle Leaves
Processing costs tell only part of the story.
Credit card transactions can be disputed after the sale. When a dispute involves a large vehicle down payment, the dealership may have already delivered the vehicle by the time the payment issue arises.
Resolving a high-dollar payment dispute can create administrative work, additional costs, and uncertainty around a transaction the dealership considered complete.
For dealerships, that makes payment protection an important part of the equation.
The question isn't simply, "Can we accept this payment?"
It's also, "What protection do we have if this payment is later returned or disputed?"
The Down Payment Is Part of Closing the Sale
The last thing an F&I manager wants is to spend significant time structuring a deal only to have the transaction stall at the final step because the down payment couldn't be completed.
Financing has been arranged. F&I products have been discussed. Documents are being finalized. The customer is ready to complete the purchase.
If the buyer has to leave the showroom to arrange payment, the dealership introduces another opportunity for the transaction to fall through.
Collecting the down payment is part of getting that transaction across the finish line.
Providing more than one way to make a high-dollar payment gives F&I the tools to complete the transaction while the customer is ready to buy. It also allows the dealership to balance payment cost and risk rather than defaulting to the same payment method for every customer.
Guaranteed ACH Provides a Digital Bank Payment Option
Customers who want to pay directly from their bank accounts don't necessarily need to write a paper check.
CrossCheck’s Pay-by-Link gives dealerships a digital option for collecting an ACH payment. The dealership sends a branded payment request by text or email, and the customer authenticates with their financial institution before authorizing the payment.
For F&I, guaranteed ACH provides another way to collect a large down payment while the customer is ready to buy.
The opportunity extends beyond the showroom. In Fixed Ops, a service customer can also choose ACH to pay a substantial repair bill, giving the dealership another payment option for high-dollar service transactions.
By adding guaranteed ACH to the dealership's payment mix, dealers can give customers another convenient way to pay while managing payment acceptance costs and gaining protection against eligible returned payments.
Guaranteed Checks Keep a Familiar Payment Option Available
Paper checks remain a practical option for customers who prefer to pay directly from their checking accounts.
With CrossCheck's Check Guarantee service, dealerships can accept eligible checks with protection against returned payments.
For F&I, a customer arriving prepared to write a personal check can complete a large down payment using a familiar payment method. In Fixed Ops, customers who prefer checks can also use them for qualifying parts and service transactions.
Guaranteed checks complement guaranteed ACH. One customer may prefer to authorize an ACH payment from a phone, while another may arrive with a checkbook in hand. The dealership can accommodate both.
Protect the Profit and Keep the Deal Moving
The goal isn't to eliminate credit cards from the dealership's payment mix. They remain one of several ways customers can pay across dealership operations.
But credit cards don't have to be the default for every high-dollar transaction.
Guaranteed ACH through Pay-by-Link and guaranteed checks through Check Guarantee give dealerships additional ways to collect funds directly from a customer's bank account while providing protection against eligible returned payments.
That choice matters across the dealership. In F&I, it can help protect the profitability of a vehicle sale when collecting a large down payment. In Fixed Ops, it gives the dealership additional ways to collect substantial parts and service payments while managing payment acceptance costs.
The result is a payment strategy built around two core dealership priorities: protecting transaction profitability and closing the sale while the buyer is ready to do business.
