Quick answer
The IST Ship Agency System for tramp shipping manages the full port call lifecycle from nomination and PDA through execution, vendor cost capture, FDA, owner reporting, and settlement.
What usually pushes buyers to change
PDA preparation depends on fragmented tariff sources and personal memory, which creates owner disputes before the vessel even arrives.
Actual disbursements are often captured late, making FDA turnaround slow and financially risky.
Vendor coordination, approvals, and supporting documents live in email chains instead of a controlled port-call record.
When this is the right time to buy
Owners or charterers are pushing for faster FDA turnaround and tighter variance control against PDA.
The agency is handling more port calls and cannot keep growing on spreadsheet-based cost control.
Management wants to reduce dispute risk and improve financial transparency around every port call.
Who this is best for
Ship agencies managing tramp, bulk, tanker, or project cargo vessel calls.
Port-call operations that must coordinate many service providers and track owner funds carefully.
Businesses that want PDA/FDA rigor without losing operational flexibility for unique calls.
Operational complexity fit
Best fit where every port call is operationally unique but still needs financial standardization.
Strong fit when multiple vendors, currencies, and owner reporting rules make manual coordination fragile.
Especially useful for agencies wanting tighter financial governance without slowing port execution.
Core capabilities
PDA Generation
Template-based PDA preparation with port-specific tariffs, currency conversion, and approval workflows.
FDA Compilation
Automatic FDA generation from captured costs with PDA variance analysis and supporting documents.
Multi-Currency Handling
Manage port call costs in local currency with conversion to owner settlement currency.
Vendor Management
Maintain vendor databases, negotiate rates, track invoices, and manage payment schedules.
Port Tariff Database
Maintain up-to-date port charges, pilotage rates, and service provider tariffs for accurate PDA estimates.
Owner Portal
Provide vessel owners with real-time port call status, PDA/FDA access, and financial transparency.
Typical integrations
Integration maturity to plan for
Identify how current port tariffs, vendors, and owner advances are maintained today.
Confirm supporting-document expectations for PDA, FDA, and settlement packs by owner type.
Map any existing accounting or treasury systems that receive owner-fund and disbursement data.
Implementation approach
Standardize port tariff sources, PDA templates, vendor master data, and cost categories first.
Move daily disbursement capture and document collection into the live port-call workflow before optimizing FDA output.
Layer owner reporting, multi-currency controls, and financial integration once the operational record is trusted.
What happens after go-live
Owner communication improves because status, costs, and supporting documents are already attached to the port-call record.
Historical port-call data becomes reusable for tariff planning, vendor negotiation, and PDA accuracy improvement.
Finance and operations spend less time reconstructing events during owner queries or audits.
Executive outcomes
Improve PDA accuracy and reduce disputes by grounding estimates in structured tariff and historical data.
Cut FDA turnaround from a manual backlog exercise to a controlled operational closeout process.
Gain a defensible audit trail from owner advance through vendor cost and final settlement.
Departmental outcomes
Operations
Live control of port-call tasks, service coordination, and document collection.
Finance
Cleaner cost capture, fund reconciliation, and faster FDA completion.
Management
Better visibility into profitability, variance, and service-provider performance by port call.
Why buyers hesitate
Every port call is different
That is exactly why the system matters. It provides structure for cost capture and settlement while still supporting non-routine execution.
Tariff data is hard to maintain
IST helps turn tariff knowledge into controlled master data instead of hidden institutional memory.
We only need better finance reporting
Better reporting comes from better operational capture. PDA-to-FDA discipline breaks if execution remains outside the system.
Commercial model considerations
The commercial payoff is strongest when PDA credibility and FDA turnaround directly influence owner trust and repeat nominations.
Port-call profitability becomes clearer when costs are captured in real time instead of reconstructed after the fact.
Buyers often start with one office or port cluster, then expand once the FDA cycle is visibly faster.
Risks of not digitizing
The more calls you handle, the harder it becomes to defend PDA assumptions and FDA timing with manual processes.
Owner disputes often come from poor cost traceability rather than the size of the cost itself.
Late disbursement capture makes branch profitability less reliable and harder to improve.
