Merchant
A business that accepts payments for goods or services via card or alternative rails.
A merchant is a business that accepts payments from customers, typically via a payment gateway and an acquiring bank. Merchants are subject to KYB checks and must follow scheme and compliance rules (e.g., PCI DSS) before transacting.
Costs for merchants include interchange fees, scheme fees, and processor markups. Choosing routing strategies (e.g., more debit vs. credit, or domestic rails like giro card) can lower acceptance costs.
