What is EDI 855?

A EDI 855 Purchase Order Acknowledgement is a type of electronic data interchange transaction set that is normally sent by a seller to a buyer in response to an EDI 850 Purchase Order. included in the confirmation the document will tell the buyer if the purchase order was accepted, rejected or requires changes. EDI 855 is often required by large retailers and distributors and may need to be sent in a specified timeframe or at particular step in your order processing workflow to ensure EDI compliance.  

This electronic document complies with the ANSI X12 EDI specification.

Benefits of the EDI 855

All EDI documents are securely encrypted in transit, allowing trading partners to send sensitive data such as pricing and contact information safely. Sending an EDI 855 eliminates the human interaction to confirm orders with customers by email, fax or phone. Additionally, the automated nature of EDI 855 helps reduce errors associated with manual retyping and the number of customer service touchpoints.

For buyers, an EDI 855 can quickly alert them to any order issues, preventing any later issues with supply, invoicing, and payments.

Improve Cash Flow

Eliminate Errors

No delays between your customer accepting or rejecting order

How is an EDI 855 Used?

Using Purchase Order Acknowledgment the seller informs the buyer whether the purchase order was accepted, rejected, or accepted with changes (it means that changes were made to the accepted EDI 850 Order)

It is sometimes mistakenly believed that EDI 997 (Functional Acknowledgment) can replace EDI 855. These two EDI messages should not be confused, as they have completely different functions.

EDI 997 is just a notification that Purchase Order (EDI 850) has been delivered and does not contain any validation to the Order.
