See everything Slice doesHalf your evening goes on rescheduling one lesson across three different WhatsApp threads.
Bank transfers that arrive “tomorrow”, cash you forgot to note down, and a spreadsheet that's always a week behind.
A player drops out, the spot stays empty, and the players who wanted it never knew it existed.
Set your weekly availability once. Players see genuine open slots and book themselves — no back-and-forth.
Players pay by card when they book; Stripe sends payouts to your bank. Cash sessions can be recorded too.
Set a player cap per class. When someone drops out, the waitlist promotes the next player automatically.
Every booking gets automatic reminders 24 hours and 2 hours before the session.
Built-in chat keeps lesson conversations in the app and your personal number private.
Most tennis coaches run their diary across WhatsApp, a spreadsheet and memory. It works — until a busy week. Slice replaces that stack with one system: players see your real availability, book themselves, pay at booking and get reminded automatically, while you see your week, your roster and your earnings in one place.
Set-up takes about five minutes in the app — availability, your first class, Stripe payouts — and your first month is on us.
