EDI 850
Purchase Order
What is an EDI 850?
An EDI 850 is a type of electronic data interchange transaction set that contains details about an order. Also known as an electronic purchase order, an EDI 850 is usually sent to a vendor as the first step in the ordering process. An EDI 850 can be used both for a single purchase, for recurring purchases, or to delete or amend an order as specified by the buyer.ย ย
EDI 850 documents follow the x12 format set by the American National Standards Institute (ANSI), a not-for-profit organisation that regulates EDI formats in the U.S.ย ย
UK and European Equivalent:ย
For businesses using the EDIFACT standard, which is commonly used in Europe and other regions, the equivalent of the EDI 850 is the ORDERS, or Purchase Order Message. This document serves a similar function by containing details about an order and is used as the initial step in the ordering process with vendors. Like the EDI 850, the ORDERS message can be used for single purchases, recurring purchases, or to amend or delete an order as specified by the buyer.ย
Comparison:ย
- EDI 850 (Purchase Order): Used in the USA, follows the ANSI x12 standard.ย
- ORDERS (Purchase Order Message): Used in Europe and other regions, follows the EDIFACT standard. Learn more about purchase order EDIFACT messages here.ย ย
Both documents are essential for initiating and managing orders in the supply chain, ensuring clear and efficient communication between buyers and vendors.

- Buyer details such as name and delivery address ย
- Buyer billing informationย
- Item identifiers, such as product SKUs or UPCโsย

How Do I Use EDI 850?
EDI 850 documents are usually sent from the buyer to the seller to initiate an order. After receiving an EDI 850 purchase order, the vendor confirms receipt with an EDI 997 Functional Acknowledgement and/or 855 Purchase Order Acknowledgement. The vendor may also respond with an EDI 810 Invoice to convey invoice details.ย ย ย
Most buyers will have specific EDI requirements that indicate which documents must be exchanged, and when. For example, a buyer may request an 855 Purchase Order Acknowledgement within a specified time frame after sending an EDI 850 purchase order. The buyer may also require an EDI 856 Advance Ship Notice previous to the shipped order arriving at the delivery address.ย ย
What are the Benefits of EDI 850?
While an EDI 850 document contains the same information as a paper purchase order, this order method offers additional benefits for both buyers and sellers.ย ย ย
In general, EDI documents are securely encrypted in transit, allowing trading partners to send sensitive data such as pricing and contact information safely. Using an EDI 850 also helps to streamline order processing, so sellers can optimise their business operations, and buyers can receive their goods quickly. For example, when an EDI 850 document is received by the sellerโs business system, automated processes can validate and verify the information, flagging any incorrect or missing data. This lets the seller quickly identify order issues and resolve those with the buyer.ย
Upon receipt of EDI 850, the sellerโs EDI software translates the document into a translated format, which can then be input, automatically or manually, into their ERP system. EDI workflows require response documents like the EDI 997, to validate that the EDI transaction was received while the seller works on fulfillment.ย
EDI Format Example
EDI 850 can be viewed in two formats โ a human โreadableโ version and a โrawโ data version. The example below shows the raw EDI data, which is then translated by your business system (ERP) to begin the fulfillment process.
