Williams-Sonoma EDI Requirements

Williams-Sonoma, Inc. (WSI) buys across a family of home-furnishings brands — Williams Sonoma, Pottery Barn, Pottery Barn Kids/Teen, West Elm, Rejuvenation, and Mark and Graham — through both DC (bulk) and drop-ship lanes. EDI on ANSI X12 (VICS) is expected for both, and because so much of WSI’s catalog is direct-to-consumer home furnishings, the drop-ship program and the 846 inventory feed carry unusual weight. The 856/ASN remains the most compliance-sensitive document.

Required EDI documents

Document	Name	Notes
EDI 850	Purchase Order	DC and drop-ship orders across brands
EDI 855	PO Acknowledgment
EDI 856	Advance Ship Notice (ASN)	most compliance-sensitive; carton-level detail tied to SSCC
EDI 810	Invoice	must reconcile to the PO and ASN
EDI 860	PO Change	conditional
EDI 865	PO Change Acknowledgment	conditional
EDI 846	Inventory Advice	central to drop-ship; frequent/daily availability feeds
EDI 997	Functional Acknowledgment

Labeling & packaging

GS1-128 (UCC-128) carton/shipping labels with a unique SSCC-18 that must match the 856 exactly.
GS1-licensed GTINs/UPCs for item identification; a GS1 company prefix is required to generate SSCCs.
Drop-ship parcels ship under WSI branded packing slips and per-brand routing/carton rules; furniture and oversized freight follow separate LTL/freight routing in the vendor guide.

Connection & portal

AS2 or an approved VAN (ANSI X12, VICS conventions); providers such as SPS, Cleo, TrueCommerce, and Logicbroker can broker connectivity.
The WSI vendor portal handles compliance visibility and the routing guide; suppliers are also onboarded to WSI’s Oracle Cloud Supplier Portal for procurement/payment. Portal access issues route to vendorcompliance@wsgc.com.

Onboarding & testing

Reported at roughly 4–8 weeks before production cutover, partner-controlled and dependent on brand and lane (DC vs. drop-ship). Certification testing for each document type is required before go-live. Confirm the current window and sequence in the WSI vendor guide.

Compliance & chargebacks

• Vendor scorecard with chargebacks/deductions for ASN, label, invoice, and drop-ship routing non-compliance; exposure reported as medium-high. Specific dollar/percentage penalties sit behind the WSI vendor portal — treat any figure as reported until confirmed.
• Invoice (810) must reconcile to the PO and ASN; mismatches are a common deduction trigger.
• Routing and packaging are governed by WSI’s vendor compliance manual / routing guide (accessed via the vendor portal) — confirm the version for your brand and lane.

Worth knowing

• WSI is multi-brand: a single vendor relationship can span Williams Sonoma, Pottery Barn, and West Elm, each with its own routing and packaging nuances under one corporate program.
• Heavy drop-ship / DTC home-furnishings mix means direct-to-consumer ship-from-vendor volume is large — branded packing slips and per-order compliance matter as much as bulk DC shipments.
• The 846 inventory advice is disproportionately important: accurate, frequent availability feeds keep drop-ship items sellable and prevent oversell/cancel penalties.

Williams-Sonoma EDI FAQ

What EDI documents does Williams-Sonoma require?

Core documents are the 850 (PO), 855 (PO acknowledgment), 856 (ASN), 810 (invoice), and 997, with 860/865 PO-change pairs and the 846 inventory advice as key conditional/program documents. Drop-ship vendors lean especially hard on the 856 and a frequent 846 feed.

Does Williams-Sonoma EDI cover Pottery Barn and West Elm?

Yes. Williams-Sonoma, Inc. runs one corporate vendor program across its brands — Williams Sonoma, Pottery Barn, Pottery Barn Kids/Teen, West Elm, Rejuvenation, and Mark and Graham — so a single EDI connection can carry orders for multiple brands, each with its own routing and packaging rules.

Why does the 846 matter so much for Williams-Sonoma?

Because so much of WSI’s catalog is drop-ship home furnishings shipped direct to consumers, the 846 inventory advice keeps availability accurate. Stale feeds lead to oversells and cancellations, which hit the vendor scorecard — so frequent, accurate 846 updates are effectively table stakes for drop-ship vendors.

EDI requirements and penalty schedules change and vary by program. Figures marked “reported” come from third-party sources, not the retailer’s published fee schedule — always confirm against the retailer’s current routing guide and your vendor agreement.
