Overstock works with two primary supplier models. Your EDI setup differs depending on how you fulfill orders — SBSA Technology supports both, often simultaneously.
Overstock sends you a PO and you ship the product directly to the customer under Overstock's branding. The most common Overstock supplier model — EDI compliance is mandatory from day one.
You supply bulk inventory to Overstock's fulfillment network. Overstock holds your products and fulfills customer orders directly. EDI compliance is required for all inbound shipments and invoicing.
Overstock supports three EDI connectivity protocols. SBSA Technology handles full setup, certification, and ongoing management — you never touch the connection layer.
Applicability Statement 2
Direct encrypted HTTPS connection between your infrastructure (or SBSA's) and Overstock's EDI gateway. Industry-standard protocol, preferred by most large retailers.
Secure File Transfer Protocol
File-based EDI delivery via secure FTP. SBSA manages the SFTP server, file naming conventions, and polling schedules on your behalf.
Value-Added Network
Third-party EDI network routing. SBSA connects through leading VANs to reach Overstock's mailbox — no direct internet connection required from your side.
SBSA Technology supports core and supplemental Overstock EDI Integration EDI documents. Critical transactions are highlighted because they carry the highest compliance risk when transmitted incorrectly or late.

Common questions from suppliers beginning their Overstock EDI compliance journey.
Overstock requires four core EDI transactions: the 850 Purchase Order (inbound from Overstock), the 855 Purchase Order Acknowledgment (outbound, within 24 hours), the 856 Advance Ship Notice (outbound, before or at the time of shipment), and the 810 Invoice (outbound, one per PO). Functional Acknowledgments (997) are also required for all transmitted documents. Optional transactions include 820 Payment Remittance, 860 PO Change Request, and 824 Application Advice.
Overstock requires the EDI 855 PO Acknowledgment to be sent within 24 hours of receiving the 850 Purchase Order. Missing this window can trigger automatic order cancellation and a compliance scorecard penalty. SBSA Technology fires the 855 automatically within minutes of receiving the PO — the 24-hour window is effectively never at risk with our integration in place.
Yes. For all drop ship orders, Overstock requires a blind packing slip — your company name, logo, and contact information must not appear on the document. The packing slip must present Overstock as the seller. SBSA Technology auto-generates the correct Overstock-branded blind packing slip from your ASN data for every drop ship PO, triggered automatically when the 856 is transmitted.
Shipping without a prior ASN is a compliance violation. Overstock's compliance scorecard tracks ASN accuracy and timing — consistent violations can result in chargebacks, reduced order volume, or account suspension. The 856 must be transmitted before or at the moment of carrier pickup. SBSA Technology fires the ASN automatically as soon as your shipment is confirmed in your ERP or WMS, ensuring the electronic record always precedes the physical movement of goods.
Yes — and as an Intuit Silver Partner, SBSA Technology has certified integrations for both QuickBooks Online and QuickBooks Enterprise. Overstock POs are automatically converted into QuickBooks sales orders, inventory is decremented on shipment, the ASN is fired from the QuickBooks shipment record, and the invoice is generated without any manual data entry. Both QuickBooks products are supported; the right choice depends on your order volume and inventory complexity.
Most Overstock EDI integrations with SBSA Technology are completed within 2 to 4 weeks. This covers connection setup (AS2, SFTP, or VAN), full transaction mapping for all required documents, ERP integration and workflow configuration, and Overstock's test environment validation before go-live. Complex multi-channel or custom ERP integrations may extend slightly beyond this range — your SBSA project manager will give you a precise timeline during the discovery phase.
Yes. Many Overstock suppliers use both fulfillment models — drop ship for certain SKUs and wholesale replenishment for others. SBSA Technology maps both PO types within a single integration, with destination-aware automation that applies the correct workflow (blind packing slip generation for drop ship, carton label requirements for wholesale) based on the PO type detected in the incoming 850. No manual routing or separate connections required.
Tell us your fulfillment model — drop ship, wholesale, or both — and we'll build a complete Overstock EDI integration plan tailored to your ERP and business.
