2. What the rules say
Plain-English summary as of November 1, 2026. Rules change; verify current rules with the card networks, your state and your own advisor. Not legal or tax advice.
For auto repair
- Many states require written estimates and customer authorization before repairs over a set amount. Check your state attorney general's auto repair rules. Source: Find your state attorney general (NAAG).
Surcharges, cash discounts and debit (all industries)
- Surcharges under card-network rules apply to credit cards only, never to debit or prepaid cards, even when a debit card is run as credit. Sources: Visa: merchant surcharging and fees; Mastercard: merchant surcharge rules.
- Network rules generally require advance notice to the network or your provider, disclosure at the store entrance (or first page online) and at checkout, and the surcharge shown as a separate receipt line. Network caps sit around 3% and may not exceed your cost of acceptance; confirm the current cap in the network rules. Sources: Visa Core Rules (public); Mastercard Rules.
- Some states ban or cap surcharges, and some state laws have been challenged in court, so the current rule in your state may differ from what you've read. Check your state attorney general's office and get advice before you start. Source: Find your state attorney general (NAAG).
- A cash discount (a lower price for cash or other non-card payment) is treated differently from a surcharge. Federal law lets merchants offer discounts for paying by cash, check or debit, and networks allow properly disclosed discount and dual-pricing programs. Signage and receipts still must be accurate. Source: 15 U.S.C. § 1693o-2 (discounts for cash, check and debit).
- Debit interchange for large issuing banks is capped under the Federal Reserve's Regulation II, which is one reason debit usually costs less than credit. Source: Federal Reserve: Regulation II (debit interchange).
- Card-interchange litigation: a proposed settlement between merchants and the major card networks has only preliminary court approval. Nothing changes for merchants until final approval is granted and the networks implement new rules. Source: Consumer Financial Protection Bureau.

Surcharge scenario (annual)
Formulas used
Annual fees = monthly card sales × 12 × effective rate
Fees as % of net profit = annual fees ÷ (annual sales × net margin)
Sales to replace fees = annual fees ÷ net margin
Savings = annual sales × 0.50% (or 1.00%)
Fees recovered = annual sales × (1 − lost %) × surcharge %
Net change = fees recovered − fees on surcharge + fees avoided − lost revenue × net margin
Simplified: applies the surcharge to all card sales; in practice debit and prepaid cards are excluded.

What are typical auto repair processing fees?

Do fleet cards cost more?
Often, because commercial cards carry higher interchange.
How do written estimates help with payments?
They document what the customer approved, which helps if a charge is disputed.
Is text-to-pay more expensive?
It's usually card-not-present, which can cost more than tapping at the counter.
