Once the balance due reaches $0, the order closes automatically.
The success state
You'll see a toast: Order complete — Tickets issued. Before you get there, the order summary shows exactly what will happen with the receipt — Send receipt to {email} if the buyer has one on file, or No email — receipt will not be sent if they don't. There's nothing further to click to trigger the email; it goes out on its own once the order completes.
The confirmation always goes to the patron or guest's own email — never to you as staff.
Finding the order afterward
Go to AdminEvents → the event → Attendees.
1Attendee list2Attendee tableAttendees list showing a box-office sale The new order appears in the list with the buyer's name, seat/section, and order id.
If you need to send the confirmation again, open the row's menu and choose Resend Confirmation. This only works if the buyer has an email on file — it can't send to a guest who never gave one.
Guests with no email
If the buyer had no email, no confirmation was ever sent — there's no ticket PDF to hand them and no way to resend one. At the door, check them in by name instead: the check-in Manual Check-in search matches name, email, order id, or seat, so the guest doesn't need to show anything to be found and checked in.
A patron who bought under a "Sell as guest" flow still gets a lightweight account behind the scenes to hold the order, but that account won't appear in the venue's searchable patron list. If they come back later wanting a receipt, you'll need their order id or the name/date of the event to locate it.
