Frequently Asked Questions
Why is the effective fee rate higher on small ticket items?
Because of the fixed $0.30 fee. On a $10.00 sale, 2.9% + $0.30 equals $0.59 (5.9% effective rate). On a $100.00 sale, 2.9% + $0.30 equals $3.20 (3.2% effective rate).
What is Interchange-Plus pricing?
Interchange-plus passes the exact wholesale Visa/Mastercard interchange cost (typically 1.5% - 2.0%) directly to the merchant plus a small fixed markup (e.g. 0.20% + $0.10), often saving high-volume businesses 20% to 30% over flat 2.9% rates.
