Interchange Optimization
Strategies and technologies to qualify transactions for the lowest possible interchange rates.
What is Interchange Optimization?
Interchange optimization refers to practices that help transactions qualify for the lowest available interchange rate categories. This includes proper transaction data capture (AVS, CVV), timely settlement, correct merchant category codes, and Level 2/3 data submission for commercial cards. Optimization ensures you're not paying higher "downgrade" rates due to technical issues or missing data that could have been provided.
Why It Matters
Without optimization, transactions may qualify for rates 0.5-1.5% higher than necessary. For a business processing $500K annually, poor optimization could cost $2,500-$7,500 in unnecessary fees. Optimization is particularly important for B2B merchants with commercial cards and any business using interchange-plus pricing.
