EDI 101

What is EDI?

EDI is an abbreviation for electronic data interchange. Using EDI, companies send information digitally from one business system to another, using a standardized format.

The term EDI describes both the transmission of the data as well as the translation into a standard data format.

EDI allows companies to exchange data electronically rather than by paper. It’s an important component for automation in business processes.

How does EDI work in retail?

EDI replaces order processes, transactions and communications that were done with paper or fax in the past.

For example, when a buying organization wants to place an order with a supplier, the buyer will create a digital purchase order. EDI software (or an EDI provider) will then make an EDI standard version of that purchase order (known as an EDI 850) and send it to the supplier.

Even though the supplier is likely using different technology than the buyer, their order system will be able to receive the information since it’s in a standard format.

The supplier will send back an acknowledgement that the order was received (an EDI 997). After the order is ready, the supplier will send another electronic communication, the invoice (EDI 810) which requests payment for the items that were purchased. And so on.

In simpler terms, EDI ensures that all of your business systems (and those of your retail partners) are speaking the same language.

There are many different types of EDI transactions. Since EDI is a standard data format, there are also specifications for each type of transaction. In addition, specs and EDI requirements can vary from retailer to retailer.

Why do retailers require EDI?

By using a standard data format for order communications, EDI-capable companies can electronically exchange order information without human intervention.

In this way, EDI provides a technical foundation for automation.

From an operational standpoint, it makes sense because it reduces human errors while also streamlining the order process. Retail companies can fulfill orders faster, cheaper and with less mistakes. 

Benefits of EDI:

EDI is proven to streamline and improve workflow while enhancing supply chain predictability.

EDI provides the foundation for automated order processing and inventory management

Make more-accurate documents and forecasts

Reduce inventory

EDI is cheaper and faster than traditional paper methods

A paper-based order can cost $70 or more per transaction, while the more efficient electronic transactions are processed for less than a dollar. Online EDI solutions eliminate hidden costs when compared to packaged EDI software. Cloud-based EDI solutions save an average of 25–75% in upfront costs, plus 50–75% in long-term expenses like software updates and hardware upgrades.

If we didn’t have SPS and we didn’t participate in EDI, we wouldn’t even be out there in most of the retail channels that we are.

Getting started with EDI?

If you’re new to EDI, you can either outsource your EDI operations to a provider or invest in your own on-premise system.


  • Requires software
  • Requires hardware
  • Requires knowledgeable resources in-house
  • Requires ongoing support within the organization to preserve EDI capabilities
  • Must develop and maintain maps and requirements for each trading partner connection

Outsourced EDI:

  • Outsourcing takes most of the work off your shoulders.
  • Managed service (uses your provider’s software/platform).
  • Requires no hardware on your end.
  • Requires no software on your end.
  • If a retail partner changes an EDI map or specification, your EDI provider will manage the change so there’s no disruption to your EDI document flow.
