Is it possible to specify event capacity?

You can specify event capacity by editing the "Event capacity" field in your event settings which can be found in "Admin" > "Events" > "Manage" > "Edit event":

You will also then need to select which of your event products are included in this calculation which can be done by checking "Include in event capacity" in your product settings. This can be found in "Admin" > "Events" > "Manage" > "Tickets/products" > "Manage" > "Edit product": 

For example, if you were running a fireworks display and selling adult and child tickets plus vouchers for the BBQ, you would only want the different ticket types to be included in the event capacity and not vouchers.

If event capacity is defined then this will automatically show the total event capacity and how many are available.

If you don't wish to show this information to your customers, check "Hide event capacity" in your event settings which can be found in "Admin" > "Events" > "Manage" > "Edit event":.

 The functionality will still be used behind the scenes but the information will not be visible to your customers:

Note: Event capacity only works with single order items - ie where there is one available. If you add a "family ticket" or any other product that has multiple items, the platform does not know how many should be deducted from the event capacity. Instead we recommend using discounts to apply an automatic discount.
