Payment operations by business model
The same payment state creates different work in every industry
EPS maps checkout, confirmation, refunds, and reconciliation to the way a merchant actually fulfills an order, booking, fee, service, or platform transaction.
Business-model fit is part of onboarding.
Availability depends on the activity, products, customers, fulfillment path, documents, payment methods, and risk review.
