Average increase in rental revenue within first year
Saved per week per administrator on rental admin
From kickoff to your first online booking
Insurance & compliance documentation captured
Rental admin shouldn’t run on spreadsheets and sticky notes.
Most schools manage facility rentals across email, paper agreements, and a calendar nobody trusts. The result? Lost revenue, frustrated renters, and hours of staff time burned every week.
Hours wasted on email tag
Admins field calls, chase signatures, and rebuild the calendar by hand. One conflict and the whole week unravels.
Revenue left on the table
Empty courts on weekends. Outdated rate cards. Renters who can't find you online — and book a competitor instead.
Compliance that keeps you up at night
Missing certificates of insurance. Unsigned waivers. One incident away from a lawsuit your district doesn't need.
One platform. Every rental. Zero spreadsheets.
A unified calendar your whole campus can trust.
Pull athletics, academics, events, and external rentals into a single source of truth. Internal stakeholders reserve spaces seamlessly. External renters see only what's available.
