We built a custom web application for booking sauna sessions. Users can pick a date, choose an available time slot, review the reservation, and complete payment — all in one simple flow. The entire system was created from scratch to match the client’s business rules, remove manual work, and deliver a smooth experience for both guests and administrators.
The client needed a booking system tailored to time-based reservations and paid entries — without relying on plugins or template limitations.
But there were two bigger problems:
1. Post-session billing was a pain
People booked, showed up, then paid later. Staff manually tracked attendance and billing — causing delays, mistakes, and unpredictable revenue.
The goal: booking = automatic payment.
2. Engagement depended on community motivation
Sessions thrived when more people joined. Users influenced each other's attendance, but the system didn't support that dynamic. The client wanted a way for the community to interact and encourage participation.
Create a simple, clear booking flow that works on every device.
Support paid reservations with secure online payments.
Eliminate manual post-session billing through automatic pre-payment.
Increase engagement by introducing a lightweight social interaction mechanic.
Give administrators control over schedules, prices, and rules — without technical knowledge.
Users select a date, pick an available slot, see a summary, and confirm the reservation with payment — all in under a minute.
The system manages session duration, capacity, overlapping times, and real-time availability — preventing double bookings and keeping the timetable clean.
Payment became mandatory during booking. Once complete, the slot is locked — no staff involvement needed. This eliminated operational overhead.
The admin panel lets the team adjust opening hours, session length, pricing, and rules — all without coding or plugins.
Since most visitors book on their phones, the interface was designed primarily for mobile screens — fast, minimal, and intuitive.
Based on user feedback, we added a participant list and comment thread for each session. This motivates early sign-ups, builds community, increases repeat bookings, and reduces cancellations — differentiating the app from standard booking tools.
