How capacity and "sold out" work
Eventually calculates Sold out status from two settings: Total Event Capacity and per-ticket Ticket Limit. An incomplete checkout can also temporarily block a seat for up to 1 hour. When a seat is available, visitors can register; when it is not, they see a sold-out message or a waitlist option.
Event-level sold out
Event is at capacity appears when the total number of registered attendees across all ticket types reaches the Total Event Capacity you set. No further registrations are accepted through the public widget unless you add an attendee manually from the dashboard.
Ticket-type sold out
This ticket type is sold out appears when a specific tier reaches its individual Ticket Limit, even if other tiers and the overall event still have space. Visitors can still register for the remaining available tiers.
Incomplete checkout holds
A visitor who starts checkout but does not finish creates an Incomplete registration. That registration holds a seat for up to 1 hour. The event or ticket tier may show as sold out during that window. Once the hour passes, the seat returns to inventory automatically. A host can also remove the Incomplete record from the Guests tab immediately to free the seat sooner.
If the buyer completes checkout after the 1-hour hold expires, they still receive their paid ticket. The order sync creates a fresh registration. The seat was available during the gap, so other visitors may have registered in the meantime.
Squarespace stock vs Eventually availability
Incomplete holds reduce availability inside Eventually, but they do not lower the product stock Eventually pushes to Squarespace. Squarespace stock counts active registrations only and, for Standard seat tiers, shared room capacity from Total Event Capacity.
That means a tier with no individual ticket limit can still show finite stock in the Squarespace cart when the event has a room cap. The cart blocks over-buys against that shared remaining count. Pending holds stay enforced on the widget and host capacity checks so the holder’s own Squarespace checkout is not blocked as out of stock. See How Squarespace sync works for the full stock rules.
What visitors see
Event is at capacity — the entire event is sold out.
This ticket type is sold out — one tier is full, but others may still be open.
[ticket name] does not have enough availability — the visitor tried to add more tickets than are currently available, sometimes because incomplete checkouts are holding seats.
Freeing up a seat
To open a spot manually:
Remove an Incomplete registration from the guest list. This returns the seat immediately.
Cancel an active Registered attendee. This frees the seat and changes the status to Cancelled.
Wait for an incomplete checkout hold to expire after 1 hour.
