Tariff Studio
Modern port tariff administration — replace PDF and Excel workflows with structured modelling, version control, publication scheduling, revenue simulation and an embeddable cost calculator that is always up to date.
Port tariffs deserve better tools
Most ports still manage tariffs in PDF documents and Excel spreadsheets — leading to version confusion, publication errors, and an inability to simulate the revenue impact of rate changes before they take effect.
Tariff Studio provides a purpose-built environment for tariff administration. Port authorities model their tariff structures in a structured editor, manage versions with full history, schedule publications and run revenue simulations — all feeding directly into the HarborCosts calculation engine and public-facing portals. An embeddable cost calculator can be placed on the port's own website, always showing calculations based on the latest published tariff version — eliminating the problem of outdated calculators that many ports struggle with today.
- PDF tariff books that are difficult to parse and integrate
- Excel spreadsheets with no version control or validation
- Manual publication workflows with error-prone effective dates
- Revenue guesswork when evaluating proposed tariff changes
- Disconnected systems that require manual re-entry of tariff data
- Outdated cost calculators on port websites that don't reflect current tariffs
- Free plan with embeddable cost calculator for your port website — upgrade for full tariff administration
Key Capabilities
Purpose-built for port tariff lifecycle management — from modelling to publication.
Define complex tariff structures with conditional rules, tiered pricing, vessel type classifications and cargo category mappings in a structured editor.
Partner accessMaintain a complete version history of every tariff change — compare versions side by side and understand exactly what changed and when.
Partner accessSchedule tariff publications in advance with effective dates, allowing ports to prepare and communicate changes before they take effect.
Partner accessAutomatically validate tariff structures for completeness, consistency and calculation correctness before publication — catch errors early.
Partner accessSimulate the revenue impact of tariff changes using historical vessel call data before committing to new rates.
Partner accessModel multiple tariff scenarios and compare their projected revenue, competitive positioning and customer impact side by side.
Partner accessPlace an interactive cost calculator on your port's website that automatically uses the latest published tariff. When tariffs are updated in Tariff Studio, the calculator updates immediately — no manual maintenance required.
Partner accessIntegration Points
Tariff Studio feeds structured tariff data to calculation engines, portals and third-party systems.
Published tariffs and cost calculations displayed for port cost transparency
Structured discount scheme rules and eligibility criteria for automated tracking

Who Uses Tariff Studio
Tariff Studio is used directly by port authorities and Arkiway as platform operator.
Tariff administrators and revenue managers who model, validate and publish port tariff schedules — replacing fragmented PDF and spreadsheet workflows with structured version control and automatic updates to calculators and portals.
Arkiway registers and maintains tariffs on behalf of ports that don't use Tariff Studio directly — ensuring all Norwegian port tariffs are available in structured format for HarborCosts, Havneportalen and APIs.
