HarborLab Port Cost & DA Management

HarborLab S.A. is a maritime software company with its address in Athens, Greece. It builds an AI-powered platform for port cost estimation and disbursement account (DA) management, used by vessel owners, technical and commercial managers, and port agents.

The platform predicts port call costs before a voyage, sources and appoints from 6,000+ verified agents, validates DA line items against live port tariffs, and passes approved accounts to accounting systems. An AI agent (HL AI) explains how each charge is calculated, translates tariffs and drafts emails for charges that deviate from tariffs.

• Port cost estimation: predicts port call costs before the voyage.
• Agent appointment: sources and appoints from 6,000+ verified agents.
• DA management: validates line items against live port tariffs.
• HL AI: explains charge calculations, translates tariffs, drafts negotiation emails.
• Payments: moves validated DAs to accounting systems.
• Benchmarking: compares costs against real port calls.

A Vietnamese shipping company could validate agent invoices across ports in Asia before payment. A ship management firm could use cost estimates to compare ports of call when planning voyages.

Flags charges that deviate from official tariffs before payment. The site states an average saving of 700 USD per port call and 2,000+ port calls handled per analyst per year (vendor figures). Centralizing DAs shortens closing time of final disbursement accounts. Benchmarking against 50,000+ port calls supports negotiation.

Shipping companies are digitalizing voyage and port expense control to cut disputed disbursement charges. Vietnamese shipowners, ship agents and logistics groups operating chartered or owned vessels can use tariff-based validation as port call volumes and costs rise across Southeast Asia.
