  • Thousandsof bookings every season
  • Shareholderin Izidoor today
  1. Before

    • An aging, unstable and buggy product with almost no users.
    • Most organizations handled bookings by phone, in Excel or on paper.
    • Others were using competing software.
  2. What I built

    • A complete back office: bookings, schedules, products, payments, statistics and a till for on-site payments.
    • An online booking module embedded in each organization’s website, with Stripe payments, deposits and refunds.
    • A multi-criteria availability engine, dynamic pricing and FFVoile, Mailjet and Twilio integrations.
  3. After

    • A reliable platform adopted by around thirty organizations.
    • Several thousand bookings every season, a volume that has held steady since I left.
    • Organizations that moved over from competing software, won over by the features.

Project description

Context

Izidoor is a SaaS booking and management platform for structures offering supervised activities: surf schools, water sports centres, ski schools, kayaking, fishing, or bike hire. The solution centralises online booking and day-to-day operations in one tool: session planning, activity and product catalogue, team and instructor management, invoicing, and on-site payment.

Each structure has a booking module integrated directly into its website, so customers can book and pay for activities online themselves.

Problem

Many leisure facilities still manage bookings with separate tools: phone, spreadsheets, manual payments, and a separate schedule.

This fragmented setup leads to:

  • a heavy administrative load
  • booking errors
  • difficulty tracking real-time availability
  • lost bookings when customers cannot reach the structure

For seasonal activities like surf, ski, or kayak, these limits quickly become a drag on daily organisation.

Solution

Izidoor centralises everything in one platform.

Structures can offer online booking directly from their site, manage their activities via an interactive schedule, and track orders, payments, and participants from the back-office.

The system supports:

  • online booking with Stripe payment
  • full or deposit payment
  • order and participant management
  • on-site payment via an integrated till
  • availability and activity period management

The platform is designed to work for surf schools, water sports centres, or independent instructors alike.

Key features

  • online booking integrated into the website
  • interactive session and activity schedule
  • product and activity management
  • instructor and team management
  • participant and customer management
  • automatic invoicing
  • till for on-site payments
  • availability and seasonal period management

Izidoor acts as a full management solution for sports and leisure facilities.

Results

Izidoor is now used by sports and leisure facilities in France to digitise booking management and simplify how they run their activities.
