Setting a registration deadline

Decide the last day players can sign up. Registration stays open through the end of the deadline day.

2 min read · Updated 18 July 2026

A registration deadline sets the last day players can sign up for a part. That gives you enough time to build the schedule and assign the courts. You set the deadline per part, so each part (each division) of an event can have its own deadline.

How the deadline works

The registration deadline is a date, not a time. Players can sign up through the end of the deadline day. So if you set the deadline to 18 July, registration stays open all that day and only closes after midnight. There is no option to pick a specific time of day.

If you leave the field empty, the start date of the part acts as the natural deadline. Players can then still sign up on the start day itself.

Once the deadline has passed, the sign-up button on the public page disappears automatically and players see a message that registration is closed. The same rule applies behind the scenes: the registration API rejects a late sign-up, even if someone still has the link. So the display and the security always reach the same verdict.

Deadline and registration mode

The deadline works together with the registration mode you choose in the same section:

  • Open: registrations are open until the deadline.
  • Open + instant entry: the same, but participants are confirmed immediately after payment.
  • Closed: no public registrations are possible.
  • List only: you show just the standings or ranking, without a registration form.

If the mode is Open or Open + instant entry, the deadline closes registration on the chosen day. If the mode is Closed or List only, signing up is not possible at all, regardless of the deadline.

A deadline is not the same as 'event over'

The registration deadline is only about signing up. Whether an event is already underway or finished depends on the start and end date, not on the deadline. A multi-day event can already have started while registration for a later part is still open, as long as that deadline is in the future.

Want to see who has signed up afterwards, or add someone manually? Take a look at managing registrations. You set the entry fee separately through setting an entry fee.
