A World Bank report jointly published with the International Association of Ports and Harbors (IAPH) offers a step-by-step guide to implementing a Port Community System (PCS) and explains its advantages for developing countries. There is often a confusion between Port Community Systems and Single Windows. While Single Windows are defined as a facility that allows parties involved in trade and transport to lodge standardized information and documents with a single entry point to fulfil all import, export, and transit-related regulatory requirements, PCS are digital collaborative platforms that enable seamless exchange of information among a port’s many stakeholders, including customs agencies, port management, shipping and logistics companies, and freight forwarders. Keceli et al. more specifically define PCSs as a "computer network which links up the port with all the companies that use it, including hauliers, rail companies, shipping lines, feeder ports, shippers and customs officers". In reality, such platforms are not necessarily designed only for ports, as they can be established for automating and streamlining information flows also at airports, dry ports, land border posts or railway terminals, as explained in our article.
