Mooring Revenue That Survives an Audit: VAT, Attribution and the Cash Box Problem

Ludvik Ludviksson
Sep 23th, 2024

Dock revenue survives an audit when every euro can be traced from the berth and the vessel to an invoice, a payment and a ledger entry, with the tax treatment applied consistently and no cash handling that depends on trust. The cash box is where this usually breaks first, because a payment taken at the pontoon has no record outside your own note of it. The other two common failures are mooring income merged into other revenue so it cannot be attributed, and a tax treatment applied differently by whoever raised the invoice. This is what an auditor looks for, and how to close each gap before it is found for you.
Key Takeaways
Every charge should be traceable to a berth, a vessel and a set of dates.
Cash at the pontoon is difficult to evidence, because there is no second record to check against.
Mooring income should be attributable as its own revenue line rather than merged into rooms.
Tax treatment should be set once by finance and applied automatically by the system.
Services, power and berth hire may be treated differently, so confirm each with your adviser.
Credit notes need to stay linked to the charge they correct.
Sequential, complete invoice numbering matters as much as the amounts.
Reconcile billed consumption and berth nights against what the dock actually delivered.
Separate the person who raises a charge from the person who reconciles the takings.
Structured electronic invoicing is now a dated obligation in several European markets.
The four things an auditor asks the dock to prove
The questions are narrower than most teams expect. Can you show that this invoice relates to a real stay, by a real vessel, on those dates. Can you show the payment that settled it and where it landed. Can you show that the tax treatment matches the treatment applied to comparable charges elsewhere in the same period. Can you produce the sequence of invoices with none missing.
A dock that runs on one operational record answers all four in minutes. A dock that runs on a berth plan, a receipt book and a monthly summary handed to accounting answers them by reconstruction, and reconstruction is what turns a routine review into an extended one.
Cash at the pontoon leaves no independent record to check against
Cash taken at the pontoon has no independent counterpart. There is no card processor record, no bank timestamp and often no invoice raised at the moment of the transaction, so the only evidence that a payment happened is the note in the box and the memory of the person who took it. That is uncomfortable for the property, unfair on the staff member, and close to impossible to evidence after the fact.
Replacing it is the highest-value change available. Card and online payment at the dock creates a processor record and a timestamp that exist outside your own system, so the payment is corroborated rather than asserted. Where cash has to be accepted, it needs an invoice raised at the point of sale, a witnessed count, and a daily banking record, which is more process than most docks want to carry once they see the alternative.
Give berth, mooring, power and service income their own revenue lines
Attribution is the second common failure. When berth hire, day moorings, power and services all land in a general account or are absorbed into room revenue, nobody can state what the marine amenity earned, and nobody can defend how it was recognised. It also removes the property's ability to manage the dock commercially, which is a separate cost of the same mistake.
What finance needs is each of those income types identifiable as its own line, traceable to the underlying charge, and comparable across periods. That is what makes the amenity auditable and manageable at the same time, and it is the same requirement discussed in the guide to growing revenue the PMS never captured.
Set the tax treatment once with your adviser, then configure it per charge type
The risk here is inconsistency rather than ignorance. Berth hire, shore power recharged to a guest, and dock-side services can attract different treatment, and the treatment can depend on the counterparty, on where the vessel is registered and on the nature of the supply. None of that is decided well by a member of staff at a pontoon on a busy afternoon.
The workable approach is for finance to determine the treatment for each charge type with your tax adviser, then configure it against those charge types so the system applies it automatically. Staff choose the charge type and the system applies the treatment. This article does not state rates or treatments because they differ by jurisdiction and by circumstance, and taking them from a general guide rather than an adviser is exactly how inconsistency enters.
Keep credit notes linked to the original charge and the invoice sequence unbroken
Auditors look closely at what was changed after the fact. A credit note that floats free of the charge it corrects, an invoice amended in place with no trace of the original, or a gap in the invoice sequence all raise questions that take time to answer even when nothing is wrong.
The system should issue invoices in an unbroken sequence, keep every correction linked to the original charge, and retain the superseded version rather than overwriting it. This is unglamorous, and it is the difference between a short review and a long one.
Reconcile berth nights and kilowatt hours monthly, not at year end
Two reconciliations matter. The first is berth nights: occupancy recorded at the dock against berth nights invoiced, which surfaces stays that were never billed. The second is power: kilowatt hours billed across the pedestals against consumption on the property's own supply for the marine circuits, which surfaces electricity delivered and never charged.
Run both monthly. A gap found in June is an operational fix with an explanation attached, while the same gap found at year end is a write-off nobody can account for. The detail of the power side is in the guide to metering and billing dock electricity.
Separate who raises a charge from who reconciles the money
Small dock teams often have one person taking bookings, raising charges, accepting payment and reconciling the day. That concentration is a control weakness regardless of how much you trust the individual, and it is one an auditor will note.
Splitting the duties rarely requires more headcount. It requires that charges are raised in a system with a user record, that payments are corroborated by a processor or bank record, and that someone other than the person at the dock reviews the reconciliation. Defined access controls per role are what make that practical rather than nominal.
Structured electronic invoicing is already a dated obligation in several markets
In several European markets the question has moved from good practice to a deadline, with invoices issued in a structured format and validated before they reach the customer. That changes the requirement on the dock, because charge data has to be complete and correct at the moment of invoicing rather than tidied up at month end.
If the property operates in Greece, the timetable and what it means for berth invoices specifically are set out in the guide to the myDATA deadline and berth invoices. Elsewhere, ask your finance team what is scheduled in your jurisdiction before you design the dock's billing process, since retrofitting is more expensive than building it correctly once.
Remove the cash box first, then attribution, then tax treatment, then reconciliation
Work in that order, because each step makes the next easier. The cash box goes first as the least defensible and the easiest to fix. Then get mooring income attributed to its own lines so the amenity is visible in the accounts. Then set the tax treatment per charge type with your adviser and configure it once. Then start the monthly reconciliations, which only produce useful answers when the three previous steps are done.
To work through what your dock would need to produce for a review, book a demo and bring your charge types, your payment methods and your current reporting to the call.

Frequently Asked Questions
1. What records should a resort dock keep for each mooring charge?
Enough to reconstruct the transaction without relying on anyone's memory: the berth, the vessel, the dates, the charge type and rate applied, the invoice with its sequential number, the payment and where it settled, and any correction linked to the original. If all of that sits in one operational record, an audit query is answered in minutes rather than reconstructed from separate files.
2. Why is taking cash at the dock a problem in an audit?
Because no independent record corroborates it. A card payment leaves a processor record and a timestamp outside your own system, while cash leaves only what your team wrote down. That is difficult to evidence, unfair on the person who handled it, and one of the first things a reviewer tends to check. If cash must be accepted, raise an invoice at the point of sale and bank it daily with a witnessed count.
3. How should mooring revenue be recognised in a hotel's accounts?
As its own identifiable revenue, separable from rooms and other outlets, with each line traceable to the charge behind it and comparable across periods. Berth, mooring, power and service income merged into a general account cannot be defended in a review and cannot be managed commercially, which are two versions of the same problem.
4. What VAT rate applies to berth hire and shore power?
That depends on your jurisdiction, the counterparty and the nature of the supply, and berth hire, recharged electricity and dock services are not necessarily treated the same way. Have your finance team confirm the treatment for each charge type with a tax adviser, then configure it against those charge types so it is applied consistently rather than decided per invoice by whoever is at the dock.
5. How often should a dock reconcile berth nights and shore power?
Monthly for both. Compare occupancy recorded at the dock against berth nights invoiced, and kilowatt hours billed against consumption on the property's supply for the marine circuits. Monthly gaps are operational fixes with an explanation attached, while annual gaps become write-offs nobody can account for.
6. Do we need to separate duties on a small dock team?
Yes, and it rarely needs extra headcount. Raise charges in a system that records which user did what, corroborate payments through a processor or bank record, and have someone other than the person working the dock review the reconciliation. Access controls set per role are what make the separation real rather than nominal.
