Everything on board
No accounting jargon. Vessia knows ships, voyages, cargo, fuel and hold surveys, and turns them into clean numbers and invoices by itself.
Loading and discharge port, cargo, tonnage, planned and actual times. Every voyage runs from planned via underway to invoiced, per ton or at a fixed price.
Your planning as a timeline. Overlapping voyages stand out, and when rescheduling you first see which other voyages are affected.
Draft invoices from your completed voyages, with five templates, your own logo and colours, automatic numbering and a crisp PDF.
Track bunkering and counter readings, consumption per voyage and per month, and the fuel clause calculated automatically on your invoice.
Six draught readings, your own calibration tables and the measured tonnage right away. With a survey report PDF as evidence.
Charterers and clients with address, VAT number and payment term. New client? Add them while creating the voyage.
Revenue, tonnage and consumption per month, your biggest clients, outstanding and overdue invoices, and how fast you get paid.
Invite your bookkeeper or a colleague with their own role: skipper, deckhand or bookkeeper. Everyone sees what belongs to their job.
The arithmetic
Freight, fuel surcharge and VAT: exactly the items where mistakes hurt. Vessia calculates them and lines them up, you keep the final say.
Completed voyages are ready as invoice lines. You pick the VAT rule, Vessia does the rest of the maths and the layout.
Per voyage you choose how the clause works: a percentage of the freight or an amount per ton. The surcharge rolls onto the invoice automatically.
