Built for the dive industry
Thalassa replaces the fragmented stack of POS, booking, waivers, training, and CRM tools with one unified platform built specifically for dive shops, charter operators, liveaboards, and dive resorts.
No credit card required · Free during early access
Designed for operators running on FareHarbor, Dive Shop 360, Rain POS, Smartwaiver, and WooCommerce. Migrate in minutes, not months.
The average dive operator stitches together 4 to 6 disconnected systems. Every booking, waiver, certification, and payment lives in a different place, and reconciling them costs hours every week.
POS in one system, bookings in another, waivers in a third. Staff switch between tabs all day. Data never syncs cleanly.
Internet goes down and your whole operation stops. No check-ins, no payments, no manifests. Unless you're on paper.
Platforms like FareHarbor charge 2 to 6% per transaction. On a $200 dive, that's $4 to $12 per booking, every booking, forever.
Thalassa covers every workflow from the moment a customer inquires to the moment their certification card is issued and their equipment is serviced and returned.
Full POS with Stripe Terminal, split payments, gift cards, barcode scanning, and thermal receipt printing. Works offline via the Mode C hub device with no internet required at the dock.
Create trip types, schedule instances, manage capacity, and take bookings online or at the counter. Manifests pre-load to the hub device for offline dock check-in and in-water roll call.
Schedule sessions, track student progress, manage skill sign-offs, and submit certifications to PADI, SSI, NAUI, SDI/TDI, RAID, and CMAS. All from one screen.
Track every piece of gear by serial number. Assign equipment to bookings, flag overdue returns, and block items under service. Size search for wetsuits, BCDs, and fins is built in.
Track hydro dates, annual service intervals, and visual inspection schedules for every cylinder and regulator. Automated alerts at 30, 7, and 1 day before due dates.
Build custom waiver templates with a drag-and-drop editor. Send signing links by email or SMS. Capture signatures on any device. Signed PDFs are stored automatically for 10 years.
Every customer's certifications, dive log, booking history, rental history, and communications in one profile. Import from FareHarbor, Dive Shop 360, Rain POS, and more.
A branded online store synced with your in-store inventory in real time. Sell products, gift cards, and course enrollments online. Inventory updates propagate in under 2 seconds.
Daily sales summaries, revenue by category, outstanding balances, and accounting exports for QuickBooks and Xero. Multi-currency support with ECB rate locking.
Native iOS and Android app for divemasters, captains, and instructors. Offline-first so manifests, roll call, and equipment fault reports work with zero connectivity.
Vessel and cabin management, voyage scheduling, onboard POS, and guest manifests. The same Mode C offline stack runs on the vessel's local network when satellite is unavailable.
Room inventory, reservations, guest folios, housekeeping tasks, and F&B charges all linked to dive bookings. Sell dive and accommodation packages as a single transaction.
Thalassa's Mode C hub runs on a Raspberry Pi or mini PC at your location. When internet goes down, your POS terminals connect to the hub over your local network. Transactions, check-ins, manifests, and roll call all work normally. Everything syncs automatically within 60 seconds of reconnection.
