How to manage a dive centre's bookings (without WhatsApp eating you alive)

What makes a dive booking special

Before comparing tools, it helps to name the problem. Managing a centre's schedule means, every week: juggling the boat capacity for each dive, checking that every diver has the level for the site and a valid certification and insurance, noting wetsuit and BCD sizes if they rent gear, taking (or not) a deposit, moving people when the weather cancels the dive, managing the waiting list when it fills up, and generating the manifest with the details of everyone on board. Multiply by two or three dives a day in season.

The 4 systems (and where each one breaks)

1 · Notebook, Excel and WhatsApp

The industry standard. It works until volume grows: the information lives in one person's head, night-time enquiries get lost (30-40% arrive out of hours), no-shows leave no trace and every booking is 10 minutes of conversation. The real cost isn't the paper: it's the hours and the bookings that never come in.

2 · Generic booking calendar

Calendly, a WordPress plugin or a generic booking tool solve "pick a time and pay". They don't know what boat capacity, a certification level, a wetsuit size or a manifest is. The operator ends up maintaining the generic system plus the same old Excel for everything the generic one doesn't cover. Double the work.

3 · Commission-based booking portal

FareHarbor and the like solve the calendar and add distribution, in exchange for ~6% of every online booking and the customer relationship living on their platform, not yours. We ran the full numbers in what FareHarbor's commission really costs: for a mid-sized centre it's thousands of euros a year, and your divers' records aren't yours.

4 · Vertical dive software

Systems built for the sector (Hexasub, Bloowatch, DEKKO) that understand dives, capacity, levels and manifests. The differences between them lie in what surrounds the calendar: your own website, automated service, diver record, app, reports. The 2026 software comparison breaks them down one by one.

The checklist: what your system must cover

• 01
  24/7 online booking on your own website, with real-time boat capacity — not a form someone processes by hand the next day.
• 02
  Diver record with certification, insurance, medical statement and sizes, which the customer fills in once and which covers all their bookings.
• 03
  Configurable deposits by activity type (try dive, dive, course) with online payment and no surcharge for the customer.
• 04
  Automatic waiting list: if someone cancels, the spot is offered to the next person automatically.
• 05
  Automatic reminders before every dive — no-shows plummet with two well-timed messages.
• 06
  Automatic boat manifest from confirmed bookings, with each diver's documents. If your port requires an official form (like the Port of Tarragona), it should come out automatically.
• 07
  Cancellations with a clear policy: who gave notice, how far in advance, what gets refunded. No arguments at the front desk.
• 08
  Out-of-hours service that captures the 23:00 enquiry and guides the customer to book on their own — without you touching your phone.
