Challenge
Turning a loose offline service into a clear digital marketplace.
Players needed a way to find tennis coaches without depending on informal referrals, scattered messages, or unclear availability. Coaches also needed a structured presence that could communicate trust, skill, location, and booking readiness.
The product had to balance two different user groups: players who wanted quick confidence before booking, and coaches who needed visibility without being buried in admin complexity.
Process
Mapping the path from discovery to confirmed session.
Booking flow structure
Reduced the booking journey into clear states so users could understand what had happened, what was pending, and what action came next.
Payment-ready experience
Designed transaction points around user confidence, making the payment moment feel like part of the service journey rather than an abrupt checkout interruption.
Solution
A scalable service platform with practical user flows.
- Built profile structures that help players compare coaches and understand suitability before taking action.
- Implemented a booking-first interaction model that reduces back-and-forth coordination.
- Integrated payments so the platform could support real transactions instead of stopping at enquiry.
- Kept the interface responsive across mobile and desktop because sports service discovery often starts on a phone.
