Keep every member, batch, fee, attendance mark and coach on one record that stays current.

Sports and fitness trades sell access to a coach, a court, a pool or a mat at a fixed time. The member joins a batch, attends on set days and pays a fee that renews, whether that fee is billed by the month, the term or the season. The cycle holds for a cricket academy with under-14 and under-16 squads, for a yoga studio with a morning class, and for a gym with a monthly pass.

The differences sit in the detail. A swimming academy counts lane capacity and levels, and moves a child up a group when a stroke is passed. A martial arts school tracks belts. A football academy keeps match squads and fixtures. A sports club keeps a membership register, a facility calendar, a committee and a bar or canteen account. Swimming pool companies sit beside them. They build pools, then service each one every week.

Parents are often the payer, not the student. A guardian pays the fee, collects the kit, signs the consent form and asks why a child missed a session last week. Coaches want a clear list for the next class. Owners want to know which batch is full. They also want to know which has gone quiet.
