Our EDI experts handle your complete Wayfair EDI setup, from connectivity and document mapping to testing and go-live, for both drop ship and CastleGate suppliers. For businesses requiring deeper automation, our technical team can integrate your Wayfair-specific 850, 855, 856, 810, and 846 transactions directly into your ERP system, building the custom logic necessary to eliminate manual entry and maintain 100% compliance.
We handle every aspect of Wayfair EDI compliance so you can focus on selling and shipping product.
We review Wayfair's EDI requirements, your fulfillment model (drop ship, CastleGate, or both), your ERP system, and current workflows to plan the right integration.
We build custom EDI maps tailored to Wayfair's specifications, including scheduled 846 inventory feeds, GS1-128 shipping labels, and packing slip requirements.
We validate every transaction set with Wayfair's EDI team, from the first 850 through the 855, 856, and 810, so you are fully compliant before going live.
Launch your fully automated Wayfair EDI connection. Orders, inventory updates, and invoices flow on their own while our team monitors and manages everything 24/7.
We support all required and optional EDI transaction sets for Wayfair drop ship and CastleGate suppliers.
Connect directly to your preferred ERP, Accounting, eCommerce, or WMS software.
"From the very beginning, their team demonstrated deep technical expertise and a clear understanding of retail compliance requirements. They worked closely with ours to ensure smooth mapping, testing, and validation across all required documents including POs, ASNs, invoices, and acknowledgements. What stood out most was their hands-on support during integration into our ERP system — they took the time to understand our workflows and customized the setup to ensure everything functioned properly with minimal disruption. If you are looking for a reliable EDI partner, I highly recommend Infocon Systems."

Wayfair suppliers typically exchange the 850 (Purchase Order), 855 (Purchase Order Acknowledgment), 856 (Advance Ship Notice), 810 (Invoice), 846 (Inventory Inquiry/Advice), and 997 (Functional Acknowledgment). Depending on your program, Wayfair may also use the 860 (Purchase Order Change Request), 870 (Order Status Report), and 820 (Remittance Advice), and CastleGate suppliers may exchange warehouse documents such as the 940 and 945. Infocon Systems, a fully managed EDI provider since 1988, supports every Wayfair transaction set and handles the mapping, testing, and ongoing compliance for you.
Most Wayfair EDI setups take a few weeks, depending on how many documents you exchange and whether you integrate with an ERP system. The work includes connectivity, document mapping, and validation with Wayfair's EDI team. Infocon Systems manages the entire process, including coordination with Wayfair, so your team is not pulled into the technical details. Web-based EDI setups generally go live faster than full ERP integrations.
Most Wayfair orders are drop shipped from the supplier's own warehouse, so Wayfair relies on the 846 Inventory Inquiry/Advice to know what it can sell. If the feed is stale or inaccurate, Wayfair sells items you cannot ship, which leads to cancelled orders and a weaker supplier scorecard. Infocon Systems automates the 846 on a schedule from your ERP, WMS, or inventory system, so Wayfair always has current quantities and nobody on your team has to key numbers into Partner Home.
Yes. Wayfair EDI can be integrated with any ERP, accounting, or warehouse system. Infocon Systems connects by API or file-based integration to systems such as NetSuite, SAP, Microsoft Dynamics, QuickBooks, Sage, and Acumatica. Wayfair 850 purchase orders flow into your system as sales orders, and your 855, 856, 810, and 846 documents are generated from your own data and sent back to Wayfair with no manual entry.
With drop ship, Wayfair sends an 850 for each customer order and you ship direct to the consumer, returning an 855, an 856 with tracking, and an 810. With CastleGate, you forward inventory in bulk to Wayfair's fulfillment network and Wayfair ships to the customer, so the document flow centers on replenishment orders, ASNs for inbound freight, and warehouse inventory reporting. Many suppliers run both models. Infocon Systems sets up and manages Wayfair EDI for drop ship, CastleGate, or both.
Wayfair requires compliant shipping labels and packing slips, and carton or pallet shipments, including CastleGate inbound freight, typically call for GS1-128 (UCC-128) labels with an SSCC-18 barcode that matches the 856 Advance Ship Notice. Infocon Systems generates Wayfair-compliant GS1-128 labels and customized packing slips directly from your order data, so the label and the ASN always agree.
Wayfair EDI pricing depends on the number of trading partners you connect, the documents you exchange, and whether you need ERP integration. Infocon Systems provides custom quotes with no per-transaction fees, and the service is fully managed, so mapping, testing, monitoring, and support are included.
