Why two identical invoices can settle at very different rates
Businesses that accept commercial, corporate, and purchasing cards pay some of the highest interchange in the system — unless they submit enhanced transaction data. Level 2 and Level 3 data give the card networks visibility into what was purchased, which reduces perceived risk and unlocks lower rate categories. In 2026 this became more consequential: certain Level 2 incentives were retired, making full Level 3 submission the primary path to reduced commercial rates. For a B2B merchant running large tickets, the difference is often the single biggest controllable cost in the account.
Level 1 is a standard consumer transaction with no additional data. Level 2 adds tax and order-reference fields. Level 3 adds full line-item detail, and it is where the meaningful rate reductions live for purchasing and government cards.
Legacy Level 2 incentive programs were sunset, so merchants that had been qualifying on Level 2 alone generally saw rates increase unless they upgraded to Level 3 submission. Assessments applied to enhanced-data commercial volume also remain in place, so the savings are real but not unlimited.
On a $5,000 commercial card invoice, the spread between a fully qualified Level 3 transaction and an unqualified Level 1 one can exceed a full percentage point — well over $50 on a single invoice. Multiply by monthly invoice count and the operational work of capturing the fields pays for itself quickly.
A gateway that supports Level 3 field submission, an invoicing or ERP integration that populates line items automatically, tax calculated and passed as a discrete field, and a customer code captured at order entry. Manual keying of these fields at the terminal is possible but rarely sustained.
B2B merchants sometimes combine approaches: enhanced data to reduce the interchange floor on commercial cards, and a cash discount or invoice-level adjustment to offset the remainder. ACH remains the lowest-cost option for recurring, high-value invoices where the customer is willing.
No. The reduced categories apply to commercial, corporate, purchasing, and government cards.
Rarely. The savings scale with ticket size, so it matters most for invoices in the hundreds or thousands of dollars.
Many can with configuration, but not all. It is worth confirming explicitly rather than assuming.
The transaction downgrades and settles at a higher interchange category, often erasing the entire benefit.
