A Squarespace order exceeded a per-order ticket limit
When a buyer edits their cart quantity on the Squarespace side after starting checkout, a paid order can complete with more tickets—or fewer—than the per-order limit you set for a ticket tier. The system flags the order for review instead of blocking the purchase.
Why this happens
Per-order minimum and maximum limits are enforced during registration and when a buyer starts Squarespace checkout. However, because the buyer can still change the quantity on the Squarespace product page or in their cart after checkout intent is created, the order may complete with a quantity that violates your limit.
What you can do
Open the event in your Eventually dashboard and go to the Guests tab.
Review the attendees from the flagged order.
Contact the buyer if you need to adjust the quantity or cancel the registration.
The buyer does not see a failure message when this happens. The order completes normally on Squarespace, and the registration is created in Eventually.
