EDI for Australian retail suppliers, explained

EDI, electronic data interchange, carries a fixed set of trading documents between your systems and the retailer's, each with a standard message type. The three that matter first are the purchase order, the invoice, and the ASN, the advance shipping notice that tells the distribution centre exactly what is arriving, on which pallets, before the truck does. Email and PDFs do not scale to this; EDI does.

Around those sit the supporting messages: the functional acknowledgement that confirms a document was received and readable, the purchase order acknowledgement that confirms you can supply, the order change, and the remittance advice that explains what the retailer actually paid against each invoice. Each retailer names and shapes these slightly differently, which is part of why no two builds are identical.

Underneath the messages sit your GS1 barcodes at unit, carton and pallet, the numbers that let a scan match a physical carton to a line on the ASN. Get the barcode hierarchy wrong and the electronic messages are perfect while the stock still fails at the door. The data and the pallet have to agree.

Builds take months, not weeks, because EDI is an integration project, not a piece of software you switch on. You are mapping your own system's fields, product codes, units of measure, tax treatment, to the retailer's exact specification, then proving every message passes their validation before they let you trade live. The software is the easy part; the agreement between two systems is the slow part.

Retailer testing runs on the retailer's calendar, not yours. You submit test messages, wait in a queue, get errors, fix, and resubmit, often across several rounds. Range reviews happen roughly every six months, so a slipped test window can push a live date by a whole cycle. None of this moves faster because you are ready and waiting.

Then there is the fulfilment side. Your third-party logistics warehouse, or 3PL, has to receive the electronic order, pick and pack to the retailer's carton and labelling rules, and send an accurate ASN back. If the warehouse and the EDI are not integrated, you have two half-built systems and a compliance problem waiting for the first order.

Accreditation is the retailer signing off that your messages, your barcodes and your fulfilment all meet their standard, and it is a gate you pass, not a form you file. It usually means a supplier setup pack, a technical mapping stage, a structured test plan for each message type, and a controlled first live order watched closely on both sides.

Supplements and therapeutic goods add a layer: those claims are scoped to TGA specialists, and Built for Retail runs the retail and fulfilment half around them. Imported goods add another; Built for Retail runs the retail half, readiness, buyer case, FSANZ labelling localisation, GS1 and EDI, and coordinates with your customs broker rather than acting as importer of record.

The work starts before the first purchase order because the first order often lands one to six months after a ranging win, and it lands whether or not your EDI is ready. The retailer decides when they issue it. If your messaging, barcodes and warehouse are not accredited by then, the order arrives, cannot be processed cleanly, and your first impression is a failure to deliver.

That is why readiness is front-loaded. GS1 registration, artwork and labelling, the 3PL integration, and the EDI mapping all have long lead times and dependencies on each other. Starting them after the buyer says yes means racing every one of them at once, against a clock the retailer controls, in the window where getting it wrong costs you the range.

Accurate EDI protects the numbers that decide whether ranging survives its first review. DIFOT, delivered in full and on time, is measured off your ASN and delivery against the purchase order; a wrong ASN can score you as late or short even when the stock is correct. Retailers read DIFOT as your reliability, and a weak score puts your range at risk.

Chargebacks, the penalties a retailer deducts for non-compliance such as a late delivery or a mislabelled carton, typically run 1 to 5 percent of invoice value and are often triggered by EDI and fulfilment errors. They stack on top of trade spend, the rebates, promotional funding and co-op you pay the retailer out of gross sales, commonly 10 to 25 percent. Sloppy EDI quietly taxes an already thin margin.

All of it feeds the pricing waterfall, the step down from your list price to what you actually keep after retailer margin, commonly 25 to 45 percent by category, trade spend and chargebacks. Model that waterfall before you sign, because EDI failures show up in it as real dollars, not abstractions.

The honest sequence is readiness first, then the buyer. Built for Retail has ranged brands as the agent into Chemist Warehouse, Woolworths, Coles and Priceline, including Dr Pickles, on Woolworths and Coles shelves today, Smile Makers, on Priceline and Chemist Warehouse, and Australian Glow, on Priceline, the founder's own brand, disclosed on a register of interests. Past rangings never promise yours; the buyer decides.

The Retail-Readiness Sprint is a fixed fee of 15,000 dollars for a single retailer, or 25,000 dollars multi-retailer, and runs about four weeks. It models your real trade spend, the pricing waterfall, the review calendar and the compliance gap, including where your EDI and fulfilment stand today. You keep the model. Sometimes its answer is not yet, and that is a cheaper answer to get now than after a failed first order. Use the contact form on this page.
