Domestic Payment

Overview

A domestic payment is a payment in which the relevant payer, payee, accounts, and processing arrangement fall within one country or domestic payment market. The definition can depend on the scheme and is not determined solely by the currencies used.

Risk analysis should cover unclear payer intent, wrong participant roles, duplicate collection, channel impersonation, hidden conversion, misleading fee-free claims, service activation before payment, escrow ambiguity, limit failures, and inconsistent refunds. The operating record should preserve the original obligation, participants, amount, currency or asset, authoritative identifiers, timestamps, state history, exceptions, and final financial effect.

Domestic Payment should remain distinct from B2B Payment and B2C Payment, because each can represent a different stage, record, control, or financial outcome.
