It is the exchange of information between computer systems of trade partners which can be characterized by sending data in an electronic form according to agreed standards. Currently, the highest standard is UN/EDIFACT. This standard includes about 200 types of business documents (e.g. purchase orders, invoices). More and more large global companies use Electronic Data Interchange. For a smaller entrepreneur, EDI implementation is a great advantage and sometimes a ticket to big business, especially as very often a cooperation with real potentates requires the use of EDI. When you are sending documents via the Internet, the EDI operator (INFINITE) guarantees confidence, security, reliability and continuity of the service provided.
