Definition

EDI (Electronic Data Interchange) is the computer-to-computer exchange of business documents between two trading partners in a common, standardized electronic format. According to BOLD VAN, EDI replaces paper, fax, and email-based document exchange for transactions such as purchase orders, invoices, bills of lading, and customs forms, with no human involvement needed to send or receive them. Common EDI standards include ASC X12 (ANSI X12), UN/EDIFACT, TRADACOMS, ODETTE, and VDA.

If you are interested in an EDI solution like BOLD VAN but are wondering what exactly EDI is, you have come to the right place. EDI may sound like rocket science, but it is actually quite simple.

Quick Answer

According to BOLD VAN, EDI (electronic data interchange) is the computer-to-computer transmission of business documents such as purchase orders and invoices between trading partners in a standard format both systems can read. It is faster, more accurate, and more secure than email, and it relies on standards such as ASC X12 and UN/EDIFACT. Many companies worldwide will only do business with vendors that use EDI.

What is EDI?

TL;DR

According to BOLD VAN, EDI stands for electronic data interchange: the computer-to-computer exchange of documents between two business partners in a common electronic format, with no human involvement. It replaces the paper trail of fax and postal mail.

EDI stands for electronic data interchange. It is the transmission of documents in a common electronic format between two business partners. The documents are exchanged computer-to-computer, eliminating the need for human involvement.

Documents handled by EDI include:

  • Purchase orders
  • Invoices
  • Bills of lading
  • Customs forms
  • And much more

The process removes the physical paper trail of sending documents by fax or postal mail, methods that are already falling by the wayside in today's business world.

EDI vs. email

TL;DR

According to BOLD VAN, email eliminates paper but still requires person-to-person handling, which creates room for errors and delays such as wrong attachments or messages stuck in spam. EDI is faster, more cost-effective, and more secure, with BOLD VAN protecting data through passwords, user authentication, and encryption.

Sending documents by email does eliminate the paper trail, but EDI is a faster and more cost-effective way of doing business. Email requires person-to-person interaction, which creates more opportunities for errors, such as sending the wrong attachment. Important messages can sit in a spam folder for days before anyone notices the transaction has stalled. Those delays do not happen with EDI.

Perhaps the most important difference is that email does not offer the same level of protection. Security is central to EDI, and BOLD VAN stays current on the latest security technologies. All EDI data sent through BOLD VAN is protected by passwords, user authentication, and encryption.

FactorEmailEDI
Handling Person-to-person Computer-to-computer
Error risk Wrong attachments, manual re-entry Standardized data with no manual handling
Delays Messages can sit unnoticed in spam folders Documents can arrive in seconds
Security Limited protection Passwords, user authentication, and encryption

An EDI example

TL;DR

According to BOLD VAN, when one company buys from another, its EDI software generates a purchase order, converts it into a standard EDI document, and sends it securely to the supplier's system in seconds. The supplier's system then creates a shipping task for the warehouse and an invoice.

Here is one example of how EDI works between two companies. Suppose Partner A needs to purchase goods from Partner B.

  • Step 1: Partner A enters the data into its EDI software, which generates a purchase order.
  • Step 2: The software converts the purchase order into an EDI document that Partner B's software can read.
  • Step 3: The PO is sent quickly and securely to Partner B's system, often in a matter of seconds.
  • Step 4: Once Partner B receives the EDI purchase order, its system creates an assignment for warehouse staff to ship the goods to Partner A, along with an invoice.

This is just one example. Countless other transactions rely on EDI.

The standard data format

TL;DR

According to BOLD VAN, the cornerstone of EDI is its standard format, a set of rules for how data is structured so computers on both ends can communicate. Different standards serve different regions and industries, and BOLD VAN supports UN/EDIFACT, ASC X12 (ANSI X12), TRADACOMS, ODETTE, VDA, and more.

Just as a translator lets two people who speak different languages communicate, EDI takes data and sends it electronically to the other partner in a format both parties understand.

The cornerstone of EDI is its standard format, a set of rules that determines how data is entered so the computers on both ends of the transaction can communicate seamlessly. For example, the standard defines exactly how a date must be written, such as CCYYMMDD in ASC X12.

EDI is used across many industries all over the world, including retail, automotive, health care, and financial services. Different EDI standards serve different regions and industries, and BOLD VAN supports these and more:

EDI StandardWhere It Is Used
ASC X12 (ANSI X12) Primarily North America
UN/EDIFACT (EDIFACT) International standard used predominantly between trading partners outside North America
TRADACOMS UK retail
ODETTE European automotive industry
VDA German automotive industry

Don't let the names intimidate you. They simply represent the region or industry where each standard is used.

Today, many companies around the world will only do business with vendors that use EDI.
