How to decide

• Check your store platform admin today for agent sales channels that are already on, and the date each was switched on.
• Decide per surface. Joining Google or Microsoft checkout keeps you merchant of record; discovery only sends the shopper to your storefront to pay.
• Agree a written position with payments and fraud before the volume arrives: allowed, allowed within limits, or handed back to the customer.
