DI, or electronic data interchange, allows companies to rapidly send information digitally, using a standard format. The annual volume of EDI transactions exceeds 20 billion per year  and in 2019, EDI accounted for 78% of all B2B electronic sales . By moving away from a paper-based exchange of business documents, companies can replace outdated, slow transactions, increase automation, and improve accuracy. Companies can streamline their processes and automate documents like purchase orders, invoices, and advance shipping notices (ASN). EDI improves the supply chain in retail, logistics, and manufacturing industries, but any business that deals with large amounts of paperwork and forms can benefit from an EDI solution.
