Purchase / Acknolegement

What is EDI 855?

EDI 855, also known as a Purchase Order Acknowledgment, is an Electronic Data Interchange (EDI) document sent by a seller to a buyer in response to an EDI 850 Purchase Order. It serves as a formal confirmation that the seller has received the order and indicates whether the order is accepted, modified, or rejected.

This acknowledgment is especially important in B2B transactions, where timely and accurate communication is essential. While an Functional Acknowledgment confirms receipt of the transmission, the EDI 855 goes a step further by confirming the content and status of the order itself.

The document adheres to the ANSI X12 EDI standard, governed by the American National Standards Institute (ANSI), and is widely used by retailers, wholesalers, and distributors to maintain order accuracy, improve supply chain efficiency, and ensure EDI compliance.


Key Components of an EDI 855 Document

The EDI 855 Purchase Order Acknowledgment contains essential data that confirms and responds to the original purchase order (EDI 850), such as:

Purchase Order Number and Date

Refers to the original EDI 850 transaction for cross-reference.

Buyer and Seller Information

Includes names, vendor numbers, contact details, and trading partner identifiers.

Line Item Details

Product SKUs, descriptions, accepted quantities, price changes, and substitutions.

Order Discrepancies or Issues

Includes inventory issues, pricing errors, delivery schedule changes, or discontinued items.

Delivery or Backorder Information

Updates on expected delivery dates or notification of backordered items.

Acknowledgment Status

Specifies if the order is fully accepted, partially accepted with changes, or rejected.

How to Use EDI 855

After receiving an EDI 850 Purchase Order, the seller reviews the order details and sends an EDI 855 as a formal response. This transaction is used to:

  • Confirm the order has been received and accepted as-is.
  • Flag any issues, such as incorrect product codes, pricing errors, or unavailable stock.
  • Suggest modifications, including quantity changes or new delivery dates.
  • Reject the order, if it cannot be fulfilled under the requested terms.

If changes are communicated via EDI 855, the buyer may respond with an EDI 860 Purchase Order Change Request, issue a new EDI 850, or contact the seller directly for clarification. A 997 Functional Acknowledgment may also be sent to confirm receipt of the EDI 855.

This automated and structured communication helps eliminate confusion, reduce delays, and improve overall order accuracy in the supply chain.

Benefits of EDI 855

Implementing EDI 855 brings several advantages for both sellers and buyers:

Secure Communication

Automated Order Confirmation

Improved Accuracy and Fewer Errors

Eliminates manual data re-entry and reduces order processing mistakes.

Faster Issue Resolution

Buyers are immediately alerted to any issues such as product unavailability or delivery delays, allowing for quick adjustments.

Better Supply Chain Visibility

 Helps both parties stay aligned throughout the order cycle, reducing late shipments and miscommunication.

Creates a Digital Audit Trail
