Supported Payment Methods
Routing Rules & Orchestration
Route WEX commercial and fleet card transactions specifically for optimized Level 2/3 data handling
Card BIN routing — WEX and fleet card BINs route to WEX, standard cards to alternative gateway
Customer-based routing — accounts that predominantly pay with fleet/commercial cards route to WEX
Amount-based routing — large commercial card transactions to WEX for best interchange qualification
Failover routing — automatic fallback for WEX transactions if connectivity is interrupted
Fee Optimization
Level 2/3 Data Enrichment Supported
PaymentHub automatically enriches transactions through WEX with Level 2 and Level 3 line-item data, qualifying B2B card transactions for lower interchange rates. Most merchants save 30-60 basis points per transaction.
WEX commercial and fleet card transactions carry some of the highest interchange rates in B2B payments — often 2.5-3.0% or more at standard rates. Proper Level 2/3 data submission can reduce these rates by 0.75–1.50% per transaction. PaymentHub ensures every WEX transaction includes the maximum qualifying data: line-item detail, commodity codes, unit costs, tax amounts, freight, and customer purchase order references. For businesses processing significant fleet or commercial card volume, the interchange savings from proper WEX data enrichment often exceed $100,000 annually.
