## Interchange Economics and Commercial Card Optimization
Corporate charge cards represent a dual-purpose tool for high-velocity enterprises: working capital float and non-dilutive cashback yield.
### Interchange Fee Breakdown on Level 3 Commercial Transactions
Standard consumer cards are capped by consumer protections in multiple jurisdictions, but commercial corporate purchasing cards operate under unregulated interchange schedules:
| Card Network & Program | Typical Interchange Fee | Maximum Rebate to Enterprise | Net Issuer Margin |
|:-----------------------------|:-----------------------:|:----------------------------:|:-----------------:|
| Visa Commercial B2B Large | 2.85% + $0.10 | 2.20% | 0.65% |
| Mastercard Corporate Elite | 2.95% + $0.10 | 2.35% | 0.60% |
| Amex Corporate Purchasing | 3.10% flat | 2.50% | 0.60% |
### Level 3 Line-Item Data Transmission
To qualify for minimum merchant interchange rates, enterprise enterprise procurement platforms transmit Level 3 line-item details (invoice number, tax amount, product code). Suppliers who accept Level 3 data enjoy reduced processing costs, enabling buyers to negotiate favorable terms.
