What to look for when choosing

For crew scheduling and availability tracking, I’d prioritize:

1. Self-service availability
   Officials should be able to enter blockout dates, preferred games, and travel constraints.

2. Conflict detection
   Avoid assigning the same official twice, overlapping games, or conflicts with teams/venues.

3. Crew assignment support
   Not just single officials — assign whole crews and role-based positions.

4. Notifications and confirmations
   Email/text/app alerts when assignments change.

5. Mobile experience Most referees will use a phone first.

6. Admin reporting Exportable schedules, assignment history, no-show tracking, and workload balance.

7. Integrations Useful if you already use a league registration system, payroll tool, or communication platform.

If you tell me:

• your sport,
• number of referees/officials,
