The final step - inviting guests to Self Check-out - will take place during your event, once sales have been entered and your guests' purchases are in their shopping carts.
Be sure to make an announcement so your guests know to check their smartphone for the message and understand any other options for checking out.
After your event concludes, it is often easier to send invitations to Self Check-out from the orders page - where you can send invitations to any user with an open order (rather than just auction bidders).
Acorn, Plus, and Professional subscribers can send invitations to Self Check-out from the Mobile Dashboard.
