The problem with the clipboard

A beach runs on six tools that never talk to each other.

The booking sheet. The cash box. The WhatsApp group for instructors. The card terminal. The accountant's spreadsheet. The loyalty stamps no one tracks. Lagoun folds all of it into one connected system — so a booking taken on the sand becomes a paid, fiscally-compliant, reconciled transaction without anyone re-typing a thing.

Without Lagoun
Double-booked instructors and walk-ups turned away
Cash that never makes it to the books
myDATA receipts done by hand at midnight
No signal on the water means no system at all
With Lagoun
Every instructor's schedule, one source of truth
Card, cash and room-charge — all reconciled automatically
Fiscal receipts filed to AADE the moment you're paid
Works fully offline, syncs the instant you're back
One platform · four apps

Every role on the beach has its own deck.

Owner, instructor, accountant and guest each get an app built for what they actually do — sharing one live backend.

Booking Tides Hunts
Offline-first

The sea has no Wi-Fi. Your business doesn't notice.

Every booking, payment and clock-in is written to a durable on-device queue with idempotency keys. Take a cash payment in the middle of the bay; the moment a bar of signal returns, it syncs — once, never twice. No spinners, no lost sales, no double charges.

Live staff radio · nobody else has this

A walkie-talkie for the whole beach, inside the app.

Push to talk and reach every instructor on the water at once — no extra hardware, no monthly radio rental. It even wakes a locked iPhone in a dry bag so the call still comes through. One channel per business, ephemeral like a real radio, nothing recorded.

Payments & Greek fiscal compliance

Get paid, and let AADE sort itself out.

Take card, cash or room-charge in the app. The instant a payment captures, Lagoun files the InvoicesDoc to myDATA — signed, numbered, year-aware — and stamps the receipt with its MARK. Cancellations issue a credit note that references the original. No spreadsheets, no midnight filing, no penalties.

Guests earn Tides on every booking, climb the beach leaderboard, unlock badges and chase the Cartographer — a real treasure hunt you pin across your property to keep them on-site when the wind drops.

We took the clipboard off the beach in a weekend. Bookings, the card machine and our accountant all live in the same place now — and the radio means I'm not running up and down the sand shouting anymore.

Questions from the shore.

Does it really work with no signal on the water?

Yes. Bookings, payments and clock-ins write to a durable queue on the device and sync the moment you reconnect — with idempotency keys so nothing is ever charged or booked twice.

Are we compliant with Greek myDATA / AADE?

Every paid transaction files a signed InvoicesDoc to myDATA automatically, with year-aware numbering and automatic credit notes on refunds. You connect your own AADE keys and keep a fiscal toggle for sandbox testing.

Do I need to buy radios for my instructors?

No. The live radio runs inside the Team app over the phones your crew already carry — one channel per business, push-to-talk, and it even wakes a locked iPhone so urgent calls get through.

How long does it take to get going?

Most beaches are taking live bookings within a day. Create your business, add services and team, connect your payment keys, and print the guest QR for your bar — that's it.

What about card fees?

You bring your own Viva Wallet account, so card processing rates stay between you and Viva. Lagoun never sits in the middle of your money.

The whole beach, one system
