TL;DR
Interchange pricing B2B determines how payment expenses are allocated between issuing banks, acquiring banks, payment networks, and merchants. The rate is influenced by the card product, transaction amount, acceptance method, risk level, and quality of transaction data—not by payment value alone.
What Interchange Pays For
Interchange moves money from the acquiring side to the issuing bank. It contributes to the issuer’s costs for:
- Transaction processing and authorization
- Fraud prevention and fraud-related losses
- Account administration and dispute handling
- Credit exposure and payment guarantees
- Commercial card offerings
For merchants, interchange is typically included in the merchant discount rate together with payment network and acquirer fees.
Why B2B Payments Are Different
B2B transactions commonly feature larger ticket sizes, remote payment acceptance, purchasing restrictions, and more extensive reconciliation requirements. These characteristics can provide greater operational value but may also increase underwriting complexity and fraud risk.
Commercial credit products are usually priced according to network schedules instead of a single statutory cap that applies universally. Business debit transactions can be regulated or exempt based on the issuer and the specific program. In the United States, Regulation II provides a benchmark for covered debit transactions: 21 cents plus five basis points of the transaction value, potentially adjusted for fraud-prevention measures.
The Main Pricing Variables
Interchange pricing B2B generally depends on the following factors:
- Card product and funding source
- Card-present or card-not-present acceptance
- Merchant category and transaction circumstances
- Authorization information and commercial data
- Settlement timing, refunds, and exposure to disputes
When required information is absent, the transaction may be assigned to a less favorable pricing category.
How Finance Teams Should Read the Cost
Break the overall payment expense into interchange, network fees, processor markup, gateway charges, fraud-prevention tools, and internal operational work. This separation helps finance teams identify which expenses are inherent and which may be subject to negotiation.
Conclusion
Interchange is made up of more than one fee. It balances issuer compensation, network access, merchant acceptance, and transaction risk. By understanding its individual components, B2B finance teams can make better-informed payment policy decisions and evaluate vendors more effectively.
