# Who is merchant of record in each protocol

In short

In ACP, UCP, Google AI Mode, Copilot Checkout, Perplexity Instant Buy and Muse purchases the merchant stays merchant of record. Visa's rules say an agent that initiates a transaction is not a merchant. So chargebacks on agent orders land on the merchant, as on any web order.
