Best B2B Credit Card Processors in the U.S. (2026): Level 2/3 Data Compared
Introduction
B2B credit card processing is very different from standard small-business payments. Interchange costs are higher, invoices are larger, and Level 2 and Level 3 data can significantly reduce fees if handled correctly.
This guide compares the best U.S. B2B credit card processors in 2026, focusing on:
Level 2 / Level 3 data support
Pricing models
Invoicing and ERP integrations
Processors which actually lower costs for B2B transactions
B2B merchants evaluating credit card processors should understand that pricing structures, data requirements, and reconciliation workflows differ significantly from consumer payments. If you’re newer to the space, this overview of how credit card processing works for U.S. businesses is a helpful baseline before diving into Level 2 and Level 3 optimization.

SMBs & wholesalers: Helcim and Payment Depot
What Is Level 2 and Level 3 Credit Card Data?
Level 2 and Level 3 data add extra transaction details to B2B and government card payments. This additional data allows card networks to lower interchange rates.
Level 2 data typically includes:
Tax amount
Invoice number
Customer reference
Level 3 data adds:
Line-item details
Product codes
Quantity and unit cost
Freight and duty amounts
Stripe or PayPal processing fees apply
Not all processors support Level 3 data correctly and partial support won’t reduce fees.
While Level 2 and Level 3 data can reduce interchange on eligible transactions, the savings depend heavily on pricing structure. In most B2B environments, interchange-plus pricing models are far more transparent than flat-rate plans, especially for high-value invoices.
