What is EDI?

The Short Version

EDI stands for Electronic Data Interchange. It's a standardized way for businesses to exchange documents — like purchase orders, invoices, and shipping notices — electronically, computer to computer, without anyone needing to retype information or send paper forms.

Think of it like this: instead of a retailer emailing you a purchase order as a PDF (which someone on your team would then manually enter into your system), EDI sends that same information as a structured electronic file that your system can read and process automatically.

Why Do Retailers Require EDI?

Major retailers like Amazon, Walmart, Target, Home Depot, and Best Buy process thousands of purchase orders every single day. They simply cannot afford the delays and errors that come with manual processes like faxes, emails, and phone calls.

EDI solves several critical problems:

• Speed — Orders that used to take days to process via mail or fax now arrive in seconds.
• Accuracy — No more typos from manual data entry. The information goes straight from their system to yours.
• Efficiency — One person can manage hundreds of orders that previously required a whole team.
• Tracking — Every document is logged, timestamped, and traceable. No more "I never got that fax."
• Cost — Eliminating paper, postage, and manual labor saves everyone money.

EDI Is Not Optional

This is the part that surprises many small suppliers: EDI is a requirement, not a suggestion. If you want to sell your products through major retailers, you must be able to send and receive EDI documents. Retailers will not make exceptions — it is written into your trading partner agreement.

In fact, many retailers will charge you chargebacks (financial penalties) if your EDI documents are late, missing, or incorrect. These chargebacks can quickly eat into your profit margins if you're not careful.

What Does EDI Actually Look Like?

Under the hood, EDI documents use a format called X12 (in North America). An X12 document looks like rows of codes and data separated by delimiters — it's not meant to be human-readable. Here's a tiny example:

BEG*00*SA*4500012345**20240115~

This line says: "This is a purchase order, number 4500012345, dated January 15, 2024."

Don't worry — you will never need to read or write these codes yourself. That's exactly what RetailReady does for you. We translate these cryptic documents into a clean, simple web interface where everything is clearly labeled and easy to understand.

The Most Common EDI Documents

You'll work with a handful of document types on a regular basis:

Each of these documents plays a specific role in the order-to-payment cycle, and RetailReady guides you through every step.
