How Olympic Surf Coach Ditched Sheets | Bloowatch
Didier Piter, European surf champion and Olympic coach, replaced Google Sheets with Bloowatch for his Hossegor surf school. Tide-aware scheduling, zero double bookings, online reservations.
A Brittany-based surf and skate school replaced spreadsheets with a platform built for their sport — and never looked back.

Founded in 1986 on the beaches of Guidel in Brittany, WSA (West Surf & Wild Skate Association) is a community-driven school teaching surf and skateboarding to all levels and all ages — from kids as young as five to adults chasing their first wave. With nearly four decades of experience, WSA is a cornerstone of the local action sports scene, running group lessons, summer camps, and competition training year-round.
The school operates at the intersection of sport, education, and coastal culture — the kind of hands-on, high-energy business where every minute spent on admin is a minute not spent in the water.
Before Bloowatch, WSA managed everything through phone calls, emails, and a custom-built Excel macro system developed by an external contractor. It technically worked — until it didn’t. Instructor schedules were rigid and hard to adjust. Adding extra sessions to a booking was clunky. Payments slipped through the cracks. And when a bug appeared, the developer wasn’t always available to fix it.
There was no real-time communication channel with clients, no easy way to send payment reminders, and accounting exports were limited. Backups were manual and unreliable. In peak season — when WSA is running at full capacity across beach and skatepark — the system buckled under pressure.
“During the busiest weeks of summer, we’d constantly think: there has to be a better way. Juggling Excel sheets while trying to run sessions on the beach just wasn’t sustainable anymore.”
WSA started using Bloowatch in 2020 — and the platform has been evolving alongside them ever since. It began with scheduling: tide-aware calendars, flexible product configurations for multi-session packages, and instant booking confirmations sent directly to clients via email.
As their needs grew, WSA upgraded to the Gold plan, unlocking the full suite: student and instructor scheduling, online payment links, an integrated online shop, accounting exports (invoices, payments, cash journal), and fast client communication for session cancellations. Digital waivers are next on the list.
“Since our first use in 2020, Bloowatch hasn’t stopped improving at every level. We now have a complete tool for scheduling, payments, our online shop, and accounting — and I’m probably still forgetting features.”



The shift was immediate and tangible. Student and instructor schedules — once the biggest headache — are now managed in real time from a single dashboard. Payment collection moved from manual follow-ups to one-click links sent remotely, which alone drove a 70% increase in payment link revenue. Accounting went from export-and-pray to structured, auditable reports.
But the real difference is operational fluidity. When a session gets cancelled due to weather, staff notify all booked students in seconds. When a client adds extra sessions, the system handles pricing variations on the fly. Everything lives in one place — no more scattered spreadsheets, no more forgotten invoices.
WSA Guidel is proof that even well-established schools with decades of experience can unlock major efficiency gains by switching to purpose-built software. The combination of sport-specific scheduling (including tide visibility), integrated payment links, and streamlined accounting has freed up an estimated 6 hours per week during peak season — time that goes straight back into coaching, community, and growing the school.
With an overall estimated sales impact of 65%, Bloowatch isn’t just a back-office tool for WSA — it’s a growth engine. And with digital waivers coming next, Loïc and his team are already looking forward to the next improvement.
““We often feel grateful for Bloowatch during peak season — it’s exactly when the platform proves its value the most.””
