EDI is the electronic exchange of standard business documents between companies in a computer-to-computer format. It allows for paperless trading of information like orders and invoices. The key benefits of EDI include time savings, improved accuracy, and better reconciliation of transactions. An EDI system converts documents to a standard format, electronically sends the files between trading partners, and generates acknowledgements of receipt. While EDI reduces errors and costs, it also requires cooperation between trading partners to agree on standards and involves upfront implementation costs that can be challenging for smaller companies. More business transactions may eventually migrate to using the internet and web-based EDI systems.
