Port Disbursement Accounts, Without the Spreadsheet

A tariff-driven platform that turns vessel particulars and a port tariff into a complete estimated disbursement account for shipping agents at Indian ports.

Bringing Precision to Port Agency Accounting

Marine Squadrons is a SaaS platform for shipping agents that prepares Estimated Port Disbursement Accounts (EPDAs). Agents enter the vessel particulars and the port of call, and the platform rates every charge from the port's published tariff, subtotals it by section, applies GST and converts it to USD.

The objective was to replace the spreadsheet every agency keeps re-keying with a system that treats an EPDA as arithmetic: rates held per port and per tariff version, every line carrying its own basis of calculation, and an account that reconciles with the invoice that follows it.

Project Overview

Client: Marine Squadrons
Industry: Maritime / Shipping Agency
Platform: SaaS Web Application

The primary goal was to let a shipping agent raise a complete, client-ready EPDA in minutes — accurate to the port’s own rounding rules, traceable line by line, and ready to send to the principal.

Challenges

Shipping agents preparing disbursement accounts by hand often struggle with:

Re-keying port dues, pilotage and berth hire rates from tariff documents for every call
Rounding and calculation-basis errors that make the estimate disagree with the final invoice
Rating stevedoring, tally and crane hire against the right tonnage for split cargo parcels
Applying GST and the USD conversion consistently across every section
Keeping each revision traceable against the vessel and voyage
Formatting accounts the way principals expect to read them

Marine Squadrons needed a platform where the tariff does the arithmetic, every figure can be explained, and the agent’s time goes into the call rather than the spreadsheet.

Our Solution

We built a tariff-driven SaaS platform that produces a complete, section-wise estimated disbursement account in three steps: enter the call, let the rates apply themselves, then issue and track.

Port Tariffs, Pre-loaded

Port dues, pilotage, berth hire and shifting rates are held per port and per tariff version, so the rates are already there when the vessel particulars are entered.

Estimates that Reconcile

Every line carries its own basis of calculation and rounds the way the port rounds, so the EPDA total matches the invoice that follows it.

Cargo-aware Line Items

A parcel can be split across commodities, with stevedoring, tally and crane hire each rated against the right tonnage.

Client-ready Output

The disbursement account is produced in the format principals expect, with subtotals by section, GST and the USD conversion.

Key Features & Capabilities

Vessel, GRT/NRT, port of call, cargo parcels and exchange rate captured per call
Published port tariffs applied automatically, with manual override for firm quotes
Sectioned accounts: port expenses, customs related, agency related and stevedoring
GST and USD conversion on every account
Revision history kept against the vessel and voyage
Role-based access for super admins, admins and agents
Self-service sign-up with a 7-day free trial and volume-based pricing tiers
Visakhapatnam live, with further Indian ports being added

Our Contribution

We designed and built Marine Squadrons end to end — the rating engine, the tariff model, the agent-facing web application and the cloud deployment — working from how agents actually prepare and send EPDAs.
Our development approach emphasized:

Accuracy first: rounding and calculation basis per line
Tariffs as versioned data, not hard-coded figures
A clean, fast interface for agents on every device
Secure, role-based access with token authentication
Subscription plans and a frictionless free trial
A scalable backend ready for new ports

Conclusion

Marine Squadrons shows how domain-aware software can take a task that lives in spreadsheets and make it fast, accurate and auditable. By holding port tariffs as data and rating every line the way the port does, the platform lets shipping agents issue estimated disbursement accounts their principals can trust — in minutes rather than hours.
