Long before the internet as we know it, businesses faced a significant challenge: how to exchange critical documents like purchase orders and invoices quickly and accurately. The answer was a mountain of paper, faxes, and manual data entry. Electronic Data Interchange (EDI) was the technology created to solve this problem, and it remains a cornerstone of the modern retail supply chain.
Electronic Data Interchange (EDI) enables retailers and suppliers to exchange critical business documents digitally, eliminating manual paperwork and errors. This blog explores how EDI technology improves order processing, inventory tracking, and payment cycles, helping retailers save time, reduce costs, and create a more agile supply chain.
It's important to understand that EDI is not simply sending a PDF invoice as an email attachment. While that is digital, it still requires a human to open the file and manually type the information into another computer system.
EDI is a computer-to-computer exchange of business documents in a standard electronic format. The data is structured in a way that the recipient's computer system can immediately read and process it without any human intervention.
Think of it this way: emailing a purchase order is like sending a letter. The recipient has to open it, read it, and act on the information. Using EDI is like the two computer systems having a direct, secure conversation in a shared, highly structured language they both instantly understand. This communication relies on globally recognised, standardised formats (like UN/EDIFACT) for different document types, ensuring everyone is speaking the same language.
In a typical retail environment, EDI automates the entire procurement-to-payment lifecycle, creating a fast and efficient communication loop between a retailer and its suppliers.
This automated, paperless cycle is the foundation of EDI for seamless inventory synchronisation. The real-time updates, especially from the ASN, ensure the retailer's IMS has full visibility of incoming stock.
Implementing EDI is about more than just reducing paper; it delivers significant strategic advantages.
While it may not be the newest technology on the block, EDI remains the silent, reliable workhorse that powers the supply chains of major retailers worldwide. It establishes a level of speed, accuracy, and efficiency that is impossible to achieve with manual processes. For any retail business looking to scale its operations, minimise errors, and build a truly agile supply chain, EDI is not just an option---it's an essential foundation.

EDI is the computer-to-computer exchange of business documents in a standard electronic format. Unlike sending an email with a PDF attachment, EDI uses a structured format that the recipient's computer system can automatically read and process without human intervention.
The EDI workflow in retail automates the entire procurement process. It begins when the retailer's inventory system automatically sends a purchase order (EDI 850) to the supplier. The supplier's system confirms with a purchase order acknowledgement (EDI 855). When goods are shipped, the supplier sends an advance ship notice (ASN - EDI 856), and finally, an invoice (EDI 810) is sent to the retailer's accounts payable system for automatic matching.
Implementing EDI offers several key benefits, including a massive reduction in errors by eliminating manual data entry, increased speed and efficiency, improved inventory management through the use of the Advance Ship Notice, and stronger supplier relationships due to a more predictable and transparent process.
An advance ship notice (ASN) is a critical EDI document that functions as a digital packing list, detailing the contents of a shipment and its scheduled arrival. It is vital for warehouse operations because it allows managers to plan for incoming deliveries, leading to faster check-in times and quicker stocking of products.
EDI fosters a more predictable and transparent relationship. Suppliers receive clear and accurate orders, while retailers get reliable, timely updates on their shipments. This improved communication and efficiency help to reduce disputes and enhance collaboration between business partners.
