Understanding PDA, FDA & SOA

The fundamental pillars of maritime financial operations. Master definitions and workflows for seamless port call management.

PDA

Proforma Disbursement Account

A preliminary estimate of port expenses prepared by the agent before the vessel's arrival. This document allows the shipowner to make an advance payment to cover expected costs.

  • Prepared before vessel arrival
  • Based on estimated tariffs
  • Used for requesting advance payment

FDA

Final Disbursement Account

The definitive account statement prepared after the vessel's departure. It includes official invoices and receipts for all actual expenses incurred during the port call.

  • Prepared after vessel departure
  • Includes actual invoices
  • Settles the difference

SOA

Statement of Account

A comprehensive financial statement summarizing the ledger between the ship owner and the agent. It details all debits, credits, and the final balance status.

  • Periodic financial summary
  • Tracks overall balance
  • Essential for reconciliation
