Wholesale & B2B

B2B and wholesale credit card processing fees

  • ACH and net terms

Effective rate = total fees ÷ total card volume

Annual fees = monthly card sales × 12 × effective rate

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 wholesale & b2b

  • Networks publish interchange categories that reward Level 2 and Level 3 data (tax amount, customer code, line items) on eligible commercial transactions. Your gateway and provider must support it. Sources: Visa: merchant surcharging and fees; Mastercard Rules.
  • Large-ticket interchange applies to qualifying commercial transactions above network thresholds; check current network tables. Source: Visa Core Rules (public).

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.

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.

4. Common questions

What is Level 2 and Level 3 data?

Extra transaction details, such as tax amount, PO number and line items, that can qualify eligible commercial card payments for lower interchange.

What are typical B2B processing fees?

As an illustrative range, about 2.3%–3.5% effective; Level 2/3 data and large-ticket rates can lower it on eligible sales.

Should B2B sellers surcharge?

Some do on credit cards, within network and state rules. Customer relationships and competitor practice matter.

Is ACH better for wholesale orders?

Often, on large low-margin orders. Weigh speed and return risk.

Do I need special software for Level 3?

Your gateway and provider must support passing the data. Ask before you assume savings.
