The system also includes CRM features, notifications, payment integrations, and tools for managing specialists and services. A key focus was creating an intuitive user experience that reduces friction during booking and improves operational efficiency. The platform was designed to support scalability for growing salons and beauty businesses with multiple locations or specialists.
