Maritime and shipping — NIS, tonnage tax, P&I
Norway operates one of the world's largest fleets with shipping companies in Bergen, Oslo and Sandnes. The sector has its own shipping taxation (tonnage model — fixed tax per net ton, not a % of profit), two ship registries (NIS = international, NOR = Norwegian), and strict P&I insurance requirements. 4b2b supports multi-flag crew payroll (A-melding for NOR, separate for NIS), tonnage tax calculation, and JV consolidation for commercial pools.

Challenge
Tonnage tax is calculated on net tons × days — not profit.
Answer
The platform records the vessel NT (net tonnage) from the IMO database and operating days per quarter, and generates the shipping tax return RF-1197.
03
Challenge
You must invoice a charterer on a TC (Time Charter) — daily hire plus bunkers reimbursement.
Answer
TC invoicing module: daily hire rate × days + actual bunkers + voyage expenses pass-through. EHF export to the charterer.
