What is the EDI 850 Purchase Order?
The
EDI 850, also known as an electronic Purchase Order, initiates the order-to-cash cycle. It communicates buyer requests to sellers electronically, replacing paper POs and streamlining procurement. Typical data includes items, prices, quantities, shipping details, and payment terms.
How does PartnerLinQ use the EDI 850 PO?
PartnerLinQ leverages the EDI 850 to optimize order intake and confirmation. Purchase Orders flow directly into ERP and OMS systems, enabling automatic acknowledgment and integration with subsequent transactions like the 856 (ASN) and 810 (Invoice). PartnerLinQ also supports complex scenarios such as cross-dock, drop-ship, direct-to-consumer, and blanket PO releases.
What are the typical responses to the EDI 850 PO?
Typical responses include:
- 997 Functional Acknowledgment (receipt confirmation)
- 855 Purchase Order Acknowledgment (acceptance or changes)
- 860 Purchase Order Change Request
- 856 Advance Ship Notice
- 810 Invoice
How is the EDI 850 supported?
The EDI 850 supports streamlined procurement, compliance with trading partner requirements, and enhanced visibility across supply chains. PartnerLinQ specifications ensure secure transmission, industry compliance, and audit readiness.
Accepting an EDI 850 from your trading partner is typically insufficient for full EDI compliance. Most trading partners will expect other EDI transactions in response to or following the purchase order such as:
- EDI-997 Functional Acknowledgement - Confirms receipt of the EDI 850
- EDI-856 Advance Ship Notice - Describes the contents of each shipment, i.e. how items were packed in the containment
- EDI-810 Invoice - Replaces the traditional paper-based invoice
Additionally, you might also be asked to trade additional EDI 850 documentation for full compliance, which may include:
- EDI 855 Order Acknowledgement - Sent in response to the EDI 850 to confirm you can meet the requirements set in the purchase order
- EDI 860 Order Change Request - Sent to request a change or to update the details of the original purchase order, assuming the order has not already been shipped
What are the Key Features of the EDI 850 PO? 
- Initiates order-to-cash lifecycle
- Supports original, change, and blanket orders
- Automates buyer-seller confirmations
- Enables integration with ERP and TMS systems
- Reduces manual processing and errors
What is the purpose of the EDI 850 Purchase Order?
The purpose of the EDI 850 is to electronically transmit purchase orders between trading partners in a secure, standardized, and automated way.

The Purchase Order (850) can also be used also to express purchase order information for receiving and other purposes such as direct import order which accelerates fulfillment, reduces costs, and increases accuracy.
