How EDI can strengthen supply chain traceability and recall readiness

When something goes wrong in the supply chain, speed matters. Whether it is a product recall, a shipment discrepancy or a batch that needs to be isolated, businesses need to know what moved, where it went and which trading partners were involved. Electronic data interchange (EDI) can help create that digital trail as part of everyday trading.

For Australian and New Zealand businesses, traceability is particularly important in sectors such as food, grocery, pharmaceuticals and retail. In Australia, Food Standards Australia New Zealand (FSANZ) reported 92 food recalls during 2025, above the 10-year average of 87. The point is not that EDI prevents every recall. It is that structured, timely transaction data can make it easier to identify affected products, trading partners and movements when action is required.

What does traceability mean in an EDI environment?

Traceability is the ability to follow products and related information through the supply chain. EDI supports this by creating consistent electronic records as business documents move between systems. Instead of relying on emails, spreadsheets or paper records, organisations can build a history of transactions that is easier to search and reconcile.
Depending on the EDI process, that history can include:

• purchase orders showing what was ordered and when
• order responses confirming what a supplier can fulfil
• advanced shipping notices (ASNs) showing what is being despatched
• SSCC information identifying logistics units such as pallets or cartons
• invoices connecting the financial transaction back to the original order
• timestamps, message status and other transaction history held within the EDI platform.

Why this matters when a recall or issue occurs

When a product issue is identified, teams often need to answer several questions quickly: Which product or batch is affected? Which customers received it? When was it shipped? How much product is still in the network? Which orders or deliveries are connected to it?

If that information is spread across inboxes, PDFs and different systems, getting a reliable answer can take time. EDI does not replace a formal recall or traceability system, but it can provide a strong digital data source to support it.

1. Create a consistent transaction trail

EDI messages follow defined structures and business rules. That consistency makes it easier to connect one transaction to another. A purchase order can be linked to an order response, despatch advice and invoice, giving teams a clearer picture of the end-to-end transaction rather than isolated documents.

2. Improve shipment-level visibility with ASNs and SSCCs

Advanced shipping notices can tell a customer what is coming before the physical delivery arrives. When SSCC labels are used, individual logistics units can also be identified and scanned through receiving and warehouse processes. This can help narrow the scope of an investigation and support faster identification of affected stock.

3. Reduce the time spent piecing records together

In a manual environment, a recall investigation can involve checking purchase orders, delivery records, emails and invoices separately. With integrated EDI, much of that information is already available electronically and can flow into ERP, warehouse or other business systems. That gives teams a stronger starting point when time is critical.

4. Support communication across trading partners

Traceability is not only an internal process. Retailers, suppliers, manufacturers and logistics providers may all need to share information. Standardised EDI messages can help keep that exchange consistent and reduce reliance on rekeying information between systems.

What data should you think about capturing?

The value of EDI for traceability depends on the quality and detail of the data being exchanged. It is worth reviewing whether your EDI messages capture the identifiers your business would need during an investigation.

• product identifiers such as GTINs or retailer item numbers
• purchase order and shipment references
• batch or lot information where relevant to the process
• quantities and dates
• supplier, customer and delivery location identifiers
• SSCCs for logistics units
• clear message status and exception information.

Not every trading relationship will use every field. The important part is making sure the data exchanged supports the way your business actually needs to track goods and transactions.

Make traceability part of normal EDI design

Traceability is easiest when it is built into everyday processes rather than treated as something to reconstruct after an incident. When designing or reviewing an EDI setup, consider the full document flow, the identifiers carried between messages and where that information is stored once it enters your systems.

It is also worth testing the process. Can your team locate a shipment from its order number? Can you identify the ASN connected to a delivery? Can you see which trading partner received a particular transaction? A practical test can highlight gaps before they become urgent.

A stronger digital trail across the supply chain

EDI is often introduced to remove manual data entry and speed up procurement. But the same structured data can also strengthen visibility and traceability across the supply chain. For businesses handling high volumes of products and transactions, that digital trail can become an important part of operational readiness.
