The short version
- Calculate the effective rate from the full statement, including fixed and account fees omitted from a quoted rate.
- Show the regular card price and lower cash price before the customer authorizes work or pays.
- Only include insurer money in card volume if it settles through the merchant card account.
- Before launch, test debit, prepaid, wallets, remote payments, refunds and supplements.
At a 3.5% effective rate, a $7,500 customer-pay repair costs $262.50 to process. That fee comes out of what remains after parts, paint, materials, payroll, rent, insurance, equipment and rework. It's money the shop earned doing the repair.
Body-shop customers usually receive an estimate and expected balance before delivery. That gives them time to arrange cash, check, ACH or another accepted non-card payment when the shop offers dual pricing. Anyone who prefers a card, including credit-card financing, sees the card price before paying.
Several people may pay parts of a collision invoice. The insurer may send a check or electronic payment. The vehicle owner may owe a deductible, betterment, an excluded operation or the whole repair. Only payments that pass through the merchant card account generate its processing bill.
To evaluate dual pricing, follow the repair order through payment. A percentage on an offer isn't enough. Customers need to see their choices before paying, and the estimate, supplement, invoice, terminal and receipt need to show consistent amounts.

Separate card collections from total repair revenue
Match the complete merchant statement to the shop's card receipts. When repair sales include insurer checks, ACH payments, financing or accounts receivable, total sales are the wrong denominator. Divide processing cost by the dollars settled through that merchant card account.
For an illustration, $54,000 collected by card with a complete monthly processing bill of $1,890 gives a 3.5% effective rate. Those figures aren't a body-shop average. Use your own statement's cost and volume for your shop's calculation.
More than $3,500 a month saved by one private shop
A body shop that switched to BlueFinch had more than $100,000 in customer-pay work each month, nearly all paid by credit card. Many customers used high-rewards cards, adding to the shop's cost under its previous account.
Eligible, configured credit-card transactions moved to a 0% merchant credit-card rate. BlueFinch's private account records show savings above $3,500 a month. The name and statements aren't public. It is one client's result, not an average or a guarantee, and monthly and other account-specific fees still apply.
Follow the payment through the repair order
A supplement doesn't necessarily mean another card payment from the customer. The insurer may cover it all, the owner's share may change, or neither payer's amount may change. Check the breakdown before sending a link or asking for payment at the terminal.
If you collect deposits, put their purpose in writing: what they reserve or buy, when work or parts can no longer be canceled, and what happens if the repair changes. The processor's settings won't settle a disagreement caused by unclear deposit terms.
| Repair stage | Payment question | Record to keep |
|---|---|---|
| Estimate | Which price was shown before the customer authorized the work? | Signed estimate with the price disclosure |
| Deductible or deposit | Which part of the bill is being paid? | Receipt identifying the payer and repair order |
| Supplement | Has the amount the customer owes changed? | Updated authorization and breakdown by payer |
| Delivery | Do the payments collected match the final invoice? | Invoice, terminal receipt, release and refund terms |
Test more than a straightforward card sale
Before training the whole front office, run these tests and keep the receipts. Check the estimate wording, terminal prompts, settlement reports, refunds and processor agreement against one another. If they describe different programs, stop and fix the setup.
- In-person credit cards, including contactless payments and digital wallets.
- Debit and prepaid cards at the same posted card price as credit. Visa and Mastercard do not allow credit-card surcharges on debit or prepaid, so this must be a dual-pricing cash-discount program, not a surcharge.
- Keyed, text-to-pay and other card-not-present payments that the approved account supports.
- Split payments, partial and full refunds, voids and a supplement paid after an earlier payment.
- A change of payment method after the customer has seen both prices.
Include every remaining cost in the comparison
A 0% merchant rate for credit and debit can reduce card cost without removing every account charge. Include any monthly, PCI, chargeback, gateway, batch, equipment or other disclosed costs. Compare twelve months using the same expected card volume and payment mix.
BlueFinch currently supplies a standalone terminal at no charge, with no equipment lease, long-term contract or cancellation fee. A launch still depends on account approval, network rules, state law, the processor agreement, supported payment channels and the shop's price display.
Questions business owners ask
Is the insurance deductible a credit-card surcharge?
No. It is the customer's share of a covered loss, separate from the payment-pricing method. If paid by credit or debit, the transaction must follow the shop's approved card-pricing program.
Do insurer checks belong in the calculator?
No. Count only payments processed through the card account. Checks, ACH, financing proceeds and unpaid invoices are not settled card volume.
Can we wait until pickup to show dual pricing?
That can surprise the customer. Show the payment choices before authorization or payment at each relevant step, including deposits and remote requests.
Will the free terminal connect to our estimating software?
The standard terminal works beside the existing system. Automatic repair-order transfer and other integrations depend on the platform and the written setup.
