THE ONE STOP SHOP

Six tools become one system of record.

Today a league runs on spreadsheets, group texts and a cash app. Post a final in GameChanger and ThreeUp moves standings, stats and the public site together.

01

Player registration

Public sign-up forms, age brackets, division placement and roster caps enforced automatically.

02

Payments & payouts

Team fees, player dues and umpire payouts tracked to the dollar. No more chasing cash apps.

03

Scheduling & fields

Generate a full season in minutes with field availability, blackout dates and rain-out rescheduling.

04

GameChanger integration

Scores and box scores flow straight in from GameChanger — accurate stats, no second scorebook.

05

Standings & stats

League leaders, team records and tiebreakers calculated for you — no more manual math.

06

Your public league site

A live site for families and fans: schedules, results, standings and announcements, always current.

BUILT FOR BOTH SIDES OF THE FENCE

One platform.Two very different jobs.

FOR COMMISSIONERS & TEAM MANAGERS

Run the league from one desk.

Set up divisions, open registration, take payments, build the schedule and publish results — without re-typing a single thing.

  • Season setup, divisions and roster rules
  • Online payments, refunds and umpire payouts
  • Auto-generated schedules with rain-out tools
  • Announcements to every team in one send
  • A public league site that updates itself

FOR PLAYERS & FAMILIES

Your season, in your pocket.

Sign up, pay your dues, see every game and track your own stats — without digging through a group text from March.

  • One-tap registration and secure dues payment
  • Your schedule, synced to your phone calendar
  • Box scores and recaps synced from GameChanger
  • Personal batting, pitching and fielding stats
  • Team news and rain-out alerts the moment they post

A FIRST LOOK

Score it once in GameChanger.

The final syncs to ThreeUp, and standings, league leaders, team pages and your public site all update in the same breath. Click through the tabs — it’s the real league site.

  • Division standings
  • League leaders & stats
  • Both team pages
  • Your public league site
