Consumer-level order volume demands automation — SBSA routes POs directly to your fulfilment system.
Big W is one of Australia's largest discount department store chains, operating over 170 stores nationwide under the Woolworths Group. As a supplier, you're entering a high-volume, compliance-driven trading relationship where EDI accuracy, on-time fulfilment, and chargeback avoidance are non-negotiable priorities.
Big W stocks a broad range of products across apparel, homewares, entertainment, toys, stationery, and seasonal categories. Its customer base spans all demographics, making it one of the highest-reach retail platforms in Australia.
As a Woolworths Group subsidiary, Big W operates under group-wide supply chain standards with centralized distribution and a sophisticated EDI compliance framework. Suppliers must meet strict GS1 labelling and ASN pre-arrival requirements.
Big W operates a growing drop ship programme for its online store, enabling suppliers to fulfil consumer orders directly. This path requires branded packing slips, carrier tracking in the ASN, and a higher order frequency than traditional wholesale supply.
Big W supports three EDI transmission protocols. SBSA Technology sets up, maintains, and monitors your connection — you never touch the infrastructure.
Applicability Statement 2
Direct, encrypted peer-to-peer EDI transmission over HTTPS. The preferred protocol for high-volume Big W suppliers. Real-time acknowledgments (MDNs) confirm every transmission.
Secure File Transfer Protocol
File-based EDI transmission via encrypted SFTP server. A reliable option for suppliers with scheduled batch processing or lower daily order frequency.
Value-Added Network
EDI routed through a third-party network intermediary. Suitable for suppliers already connected to a VAN for other trading partners — no additional direct connection required.
SBSA Technology supports core and supplemental Big W EDI Integration EDI documents. Critical transactions are highlighted because they carry the highest compliance risk when transmitted incorrectly or late.
Inbound from Big W. Contains order lines, quantities, ship-to destination, and delivery window. SBSA maps this directly into your ERP or WMS.
InboundConfirms receipt of the 850, line-level quantities, and expected ship dates. Must be sent within Big W's required acknowledgment window — SBSA automates this.
OutboundMust be transmitted before the shipment physically arrives. Contains carton-level detail, GS1-128 label data, and carrier tracking. Late or missing ASNs generate chargebacks.
OutboundElectronic invoice transmitted to Big W accounts payable following ASN acceptance. SBSA auto-generates from ASN data, eliminating manual invoicing effort.
OutboundIssued by Big W to modify an existing PO — quantity adjustments, date changes, or cancellations. SBSA maps changes back to your ERP and triggers re-acknowledgment.
InboundFunctional acknowledgment from Big W indicating whether a transmitted document was accepted or rejected. SBSA monitors all 824s and alerts your team on exceptions.
InboundSBSA Technology provides pre-built ERP integrations that simplify EDI implementation, automate document exchange, and reduce onboarding time.

If your ERP or WMS isn't listed, SBSA builds a custom integration. We've connected EDI to hundreds of systems — flat-file imports, AS/400 mainframes, proprietary ERPs, and everything in between.
SBSA Technology automates every stage of the Big W supplier workflow — from the moment a PO arrives to the moment your invoice is acknowledged. Your team focuses on fulfilment; we handle the compliance.

Compliance Monitoring & Alerts
Common questions from suppliers beginning their Big W EDI compliance journey.
Big W requires four core EDI documents: the EDI 850 Purchase Order (inbound), the EDI 855 PO Acknowledgment (outbound), the EDI 856 Advance Ship Notice (outbound), and the EDI 810 Invoice (outbound). The 856 ASN is the document most frequently associated with chargebacks — it must reach Big W before the physical shipment arrives at its destination. SBSA Technology handles all four automatically.
Big W suppliers ship to one of three destinations specified in the EDI 850: (1) a Big W Distribution Centre — the standard wholesale replenishment model; (2) a Big W store — same EDI requirements as DC shipments but delivered to a store address; or (3) directly to the end consumer as a drop ship order, where Big W's branded packing slip is mandatory and the customer's address is embedded in the 850 PO. SBSA handles all three paths with destination-aware automation.
Big W enforces strict pre-arrival ASN compliance. Any shipment received at a Big W location without a prior 856 ASN, or with an ASN that arrives after the goods, is subject to chargebacks and potential rejection. A refused shipment means the goods are returned at your cost — one of the most expensive outcomes in supplier compliance. SBSA transmits the 856 ASN automatically the moment your shipment leaves your facility, preventing this scenario entirely.
Yes. Big W requires GS1-compliant barcodes on all product units and GS1-128 shipping labels on every carton. The labels must be generated from your ASN data and applied before despatch. Big W's receiving teams scan cartons on arrival — non-compliant labels are rejected at the dock. SBSA Technology generates fully compliant labels as part of the automated outbound workflow.
Big W expects all orders to be shipped complete. If you cannot fulfil certain line items, you must communicate this in your EDI 855 PO Acknowledgment — updating quantities or providing a revised availability date at line level. Do not enter a quantity of zero on the ASN for an unfulfillable item — remove the line entirely, as a zero-quantity line is a compliance violation. Partial shipments without prior approval may trigger chargebacks.
Yes. As an Intuit Silver Partner, SBSA Technology provides certified integrations for both QuickBooks Online and QuickBooks Enterprise. Big W purchase orders are mapped as inbound documents, acknowledgments and ASNs are triggered from within QuickBooks workflows, and invoices are generated automatically from shipment data. The integration eliminates all manual data entry between your QuickBooks environment and Big W's EDI system.
Typical onboarding takes 2–4 weeks from initial kick-off to first live transaction, depending on your ERP complexity and the number of fulfilment paths required. SBSA manages the entire process — connection setup, ERP mapping, GS1 label configuration, Big W testing, and final certification. You're never left to navigate Big W's technical requirements alone.
Tell us your fulfilment path — DC, store, or drop ship — and we'll build a complete integration plan tailored to your ERP and order volume.
