Open Settings, then Teams & Registration.
Registration Codes: teams must type a code to join. Choose One shared code or Single-use codes, then click Save.
Entry fee: switch on This tournament requires an entry fee. You then mark each team as paid or not paid. It only records paid or not paid, with no amounts.
Waitlist: switch on Enable waitlist. When the tournament is full, new sign-ups wait. Freed spots go to the next person, automatically if Promote automatically is on. Read more in how to use a waitlist.
Pair registration: in padel, tennis and other doubles sports, players can sign up as a pair. See how to let players sign up as pairs.
Registration Codes and Entry fee need a paid plan or a tournament credit. Waitlist needs a PRO or BUSINESS plan. An Event Pass does not unlock it.
