Short answer
Extra transaction data, such as the sales tax amount and a customer or purchase order code, sent with a business card payment.
Business, corporate and purchasing cards carry high interchange. Sending Level 2 data with the payment can qualify it for lower commercial-card rates, because the buyer’s company gets better information for its expense controls.
Whether Level 2 still lowers costs depends on the card network’s current rules, which changed for Visa in 2025. See Level 2 and Level 3 card processing for what applies now.
