EDI is a general name for a number of techniques to communicate electronically (via e-mail or an FTP server) with your supplier. By linking your POS system of business software directly to the sales software of the supplier you save a lot of time and you have less errors in your supply chain.
EDI documents contain the same data that would normally be found in a paper document used for the same organisational function. An EDI document may contain a ship to address, bill to address, a list of product numbers (usually a UPC code) and quantities. It may have other information if the parties agree to include it.
