Berths, moorings and poles sit on a live map with occupancy and payment status, so the Saturday changeover is read from one screen instead of assembled from a berth plan and three phone calls. Vessels carry length, beam and draft, and a boat is matched to a berth that actually fits, which is what stops a charter arriving to a space it cannot safely take. Arrivals can be booked in advance with a stated time, so the dock team knows what is coming, and regular visitors and tender runs can book and pay themselves rather than going through the concierge each time.

Shore power is metered and billed from real consumption, so the conversation at departure is about a reading the guest can check rather than a number someone estimated. Charges are settled at the dock by card, or put on account for the charter companies and agencies you invoice on a cycle, and seasonal berth holders run on recurring billing. Every charge stays tied to the berth, the vessel and the dates, which is what gives finance a marine revenue line they can reconcile alongside rooms, food and beverage and spa. The full case for running all of this without touching the system that runs your rooms is on the page about marine operations alongside your PMS.

There is a practical reason that record matters more in Croatia than it did two years ago. Since 1 January 2026 the Zakon o fiskalizaciji requires structured e-invoices between VAT-registered businesses established in Croatia, reported to the Tax Administration as they are issued, and fiscalisation now reaches consumer payments settled by bank transfer as well as cash and card. In plain terms, the charge data has to be right when the invoice goes out rather than tidied up at month end, which is difficult when the dock runs on notes. Harba is not a fiscalisation or e-invoicing provider, so your channel and your tax advice stay with your own advisers; what it does is make sure the underlying charges are complete and traceable when they reach it. The Tax Administration's Fiskalizacija eRačuna pages and the text of the Act in Narodne novine 89/2025 are the sources worth giving your finance team. Greek properties face the same question on a different timetable, set out in the guide to the myDATA deadline and berth invoices.
