Clinics by ball colour, lessons by the half hour.

Three things that bite in tennis.

Players are grouped by ball colour, not by birthday.

A tennis program starts with its levels already named — Yellow, Green, Orange and Red ball, top to bottom — and every group carries its level as a badge. Each clinic is its own registration option with its own price and capacity, and the levels rename or reorder if your program says it differently.

Private lessons fill the week, and they are booked by text message.

Families book private and small-group lessons on their phone from the coach’s open times, paid at booking or from a lesson pack, and a booked lesson can move rather than cancel. Coach pay by the hour of lessons is in the coach earnings report.

Rain takes a clinic morning every week or two.

Cancel that one date on the clinic itself and it stays on every family’s calendar, struck through, with your reason — so the parent checking at seven in the morning sees it, and the rest of the session is untouched.
