EDI and B2B


EDI is the exchange of data between computer systems, using standard document formats known as transaction sets. It is extremely useful if you routinely transmit large volumes of repetitive documents.

Why Use EDI?
  • Reduces costs for administration and materials
  • Data is processed quickly and accurately
EDI Transaction Sets Supported at CSX
Response/Control Transactions

B2B (Business to Business)

B2B is a secure communications tool for exchanging data between computer systems, using any file format. It is useful if you do not have the capability to create EDI documents, as CSX can transform your data files into our preferred format and vice versa.

Why Use B2B?
  • Eliminates the need to use another company, or VAN (Value Added Network), to translate file formats
  • Eliminates delays and additional costs associated with using VANs
  • Includes the capability to make changes to data
