EDI 850 Process

The EDI 850 purchase order is generated through the buyer’s business system, the data is translated into an EDI format and the EDI document is then transmitted through the buyer’s preferred communication method to the supplier. A few communication methods can include: AS2, SFTP, VAN, HTTPS.


The supplier will receive the EDI 850 purchase order and respond back with the buyer’s required response document. Usually response documents can include the EDI 855, EDI 856 and/or EDI 810. With DataTrans WebEDI, the supplier will generate the response document that will contain the relevant information. DataTrans intuitive web forms minimize data entry by auto-populating pertinent details from the 850 onto the response document. Once sent, the data will be translated and transmitted back through the buyer’s preferred communication method.
