Bookkeeping for marinas
A marina earns differently every month: annual slip contracts, seasonal storage, transient dockage, fuel and the service yard all peak at different times. Off-season costs run year-round while revenue concentrates in a few months. Mispar keeps every revenue line distinct and reconciled, so the year's real economics are visible in any month. Plans start at $229/mo.
Best for: Independent marinas, boat yards and mooring operators with slip rental, storage, fuel or service revenue, from single basins to multi-operation sites.

Where marina books usually go wrong
- Slip and storage rent paid in advance booked at receipt.
- Fuel dock and service income combined.
- Seasonal cash swings ignored.
How Mispar keeps your marina books clean
Industry-specific accounts and categorization, with the reporting scope agreed before work starts.
Slip and mooring contracts
Record each slip contract and reconcile billings to payments, keeping seasonal and annual terms distinct and renewals visible.
Winter and seasonal storage
Track storage contracts, haul-outs and launches on their own lines, so the storage season's revenue is matched to its costs.
Fuel dock sales
Reconcile fuel deliveries to gallons sold and payouts to deposits, keeping fuel margin per period real.
Service and repair tickets
Record parts and labor per work order, so service revenue carries its true cost and unbilled work surfaces.
Ship store and miscellaneous sales
Keep store sales, dockage extras and rental income on distinct lines, so ancillary revenue is measured on its own.
Dock, equipment and insurance costs
Track dock maintenance, equipment, dredging reserves as agreed and insurance on their own lines, keeping waterfront fixed costs visible.
Reports a marina can use
- Slip revenue and prepaid balances.
- Fuel margin on its own line.
- Seasonal cash plan.
A simple, predictable process
From kickoff to your first clean close, here is exactly what happens.
Review your current records
We start from your slip contracts, POS and fuel reports, work orders and bank feeds.
Map the chart of accounts
Revenue lines and waterfront costs are mapped to an agreed chart of accounts.
Reconcile contracts and sales monthly
Slip billings, fuel activity and service tickets are reconciled with exceptions listed.
Close the month
Monthly statements with an exceptions list and the per-line reporting agreed for your marina.
Illustrative example
A marina with a hundred slips, a fuel dock and a small service yard heads into winter. Storage contracts are billed and reconciled per boat, fuel margin closes the season as a real number, and the owner sees which revenue lines actually carried the year's fixed costs. This is an illustration of the method, not a customer case or a guarantee.
Marinas bookkeeping — your questions
How do you handle annual slip contracts billed upfront?
Contract billings are recorded and recognized under the schedule agreed with your CPA, with the deposit or prepayment tracked until earned.
Can you keep fuel sales separate from slip revenue?
Yes. Fuel, slips, storage, service and store sales each stay on their own lines, so each operation inside the marina is measured.
How are service work orders tracked?
Parts and labor are recorded per ticket, so each job's billing matches its cost and nothing finished goes unbilled.
What about seasonal revenue swings?
Monthly closes show each line as it happens, so the strong season and the quiet one are both real in the books, and year-round costs are planned against them.
How do you treat prepaid slip rent?
It is held until the period it covers.
Does the $229 starting plan cover my marina?
The final plan and scope depend on revenue lines, volume and accounts. We agree that scope before starting; catch-up work is discussed separately.
