Session Management

Track Makeup Sessions and Remaining Balances Clearly

Avoid confusion around canceled sessions, makeup classes, and package deductions.

Built for small business owners, solo operators, and family-run shops that need prepaid tracking without a complex CRM.

Common tracking problems

Without a clear log, canceled sessions and makeup sessions cause package balance disputes and extra admin time.

Cancellation notes

Record why and when a session was canceled.

Makeup session logs

Link makeup sessions to original missed visits.

Balance integrity

Only deduct sessions that were actually delivered.

Operational workflow

  1. Log cancellations with clear reason and date.
  2. Schedule and record makeup session details.
  3. Deduct package only after completed service.
  4. Review remaining sessions with client regularly.
