Temperature-sensitive products require carrier and handling codes in the ASN. SBSA enforces these fields.
Specialty suppliers face tighter OTIF windows. SBSA surfaces risk before your scorecard is impacted.
GM POs may target store, DC, or centralized distribution — SBSA handles all three without manual intervention.
High-volume seasonal drops require rapid 855 turnaround and bulk ASN generation. SBSA scales automatically.
Every carton requires a GS1-128 label matching the ASN content. SBSA validates label-to-ASN alignment before dispatch.
One EDI 810 per purchase order, no exceptions. SBSA enforces this at the automation layer.
Walgreens works with a broad supplier ecosystem. Each category has specific EDI requirements — SBSA Technology has pre-built compliance workflows for all of them.

Walgreens accepts three EDI transmission protocols. SBSA Technology configures, manages, and monitors all three — you choose the method that fits your infrastructure.
Direct Secure Connection
The preferred protocol for Walgreens direct trading partners. Real-time MDN receipts confirm delivery of every document — no ambiguity about whether Walgreens received your ASN or invoice.
Secure File Transfer
Secure FTP-based EDI exchange. SBSA manages inbound polling intervals, file naming conventions, and directory structures exactly as Walgreens specifies — preventing silent delivery failures.
Value-Added Network
For suppliers already using a VAN provider (SPS Commerce, TrueCommerce, 1 EDI Source, etc.), SBSA configures the Walgreens mailbox and manages interchange routing without requiring you to switch networks.
SBSA Technology supports core and supplemental Walgreens EDI Integration EDI documents. Critical transactions are highlighted because they carry the highest compliance risk when transmitted incorrectly or late.
Walgreens sends POs for DC replenishment, store orders, and promotional buys. Each PO specifies delivery window, destination, and OTIF accountability dates.
InboundMust be returned within 1 business day of PO date. Confirms acceptance, line-level quantities, and ship dates. Late acknowledgments affect your OTIF scorecard.
Outbound Auto-fired by SBSA within minutes of PO receiptTransmitted the moment your shipment departs. Must include GS1-128 carton details, carrier information, tracking number, and pro number. Missing or late ASNs trigger chargebacks.
Outbound Must arrive before physical shipment — chargeback riskOne invoice per purchase order. SBSA auto-generates the 810 with correct Walgreens header and reference fields — duplicate invoices are blocked at the automation layer.
Outbound One invoice per PO — duplicates cause payment delaysConfirms syntactic validity of every transmitted EDI document. SBSA monitors all 997 responses and escalates rejections before they cause compliance events.
OutboundWalgreens payment and remittance advice. When enabled, SBSA auto-reconciles remittance data against open invoices in your ERP — eliminating manual cash application.
InboundBuyer-initiated modifications to open POs — quantity adjustments, delivery date changes, or line cancellations. SBSA applies changes automatically at the line-item level.
InboundEnables Walgreens to query your real-time inventory levels — supports replenishment planning and helps prevent out-of-stock situations at the DC or store level.
OutboundSBSA Technology integrates Walgreens EDI with your ERP, WMS, and accounting platform — eliminating manual data entry and accelerating the order-to-cash cycle. We are an Intuit Silver Partner for both QuickBooks platforms.
SBSA maps Walgreens POs directly into QuickBooks Online as sales orders, creates invoices on shipment, and syncs inventory quantities — all in real time without manual entry.
For higher-volume suppliers using QuickBooks Enterprise, SBSA provides deep integration with advanced inventory, multi-location tracking, and sales order management — fully connected to Walgreens EDI.
Native NetSuite integration using SuiteScript connectors. POs enter as Sales Orders, fulfillments trigger the ASN, and invoices close out the order cycle automatically.
SAP integration via IDOC or REST API. Walgreens POs map to SAP Sales Orders with full line-item fidelity. Goods Issue triggers automatic ASN generation and transmission.
Dynamics 365 and Business Central connectors map Walgreens EDI documents to native Dynamics entities — purchase orders, shipments, and invoices — without custom development.
Integration with Oracle Fusion Order Management and Inventory. SBSA maps Walgreens 850s to Oracle sales orders and returns 856/810 from Oracle confirmations.
For brands using Shopify as their OMS or third-party WMS platforms (ShipBob, 3PL Central, Logiwa, etc.), SBSA provides API-based integrations that route Walgreens orders into your fulfillment workflow.
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.
Walgreens' OTIF and ASN enforcement policies are designed to protect their supply chain — and the penalties for non-compliance are real. SBSA Technology automates every compliance step so your Walgreens relationship stays profitable and penalty-free.

Common questions from suppliers beginning their Walgreens EDI compliance journey.
The four core required transactions are: EDI 850 (Purchase Order, inbound from Walgreens), EDI 855 (PO Acknowledgment, outbound within 1 business day), EDI 856 (Advance Ship Notice, outbound before physical delivery), and EDI 810 (Invoice, one per PO). Optional but recommended transactions include 997 (Functional Acknowledgment), 820 (Payment Remittance), 860 (PO Change Request), and 846 (Inventory Inquiry). SBSA manages all required and optional documents in a single integrated platform.

Walgreens enforces On-Time In-Full (OTIF) compliance — shipments must arrive within the delivery window specified on the PO and must include the correct quantities. Failures generate chargebacks calculated as a percentage of the affected PO value. Common chargeback triggers include late delivery, short shipment, missing or late ASN, and carton labeling errors. SBSA monitors every open PO against the OTIF window and surfaces alerts before a shipment becomes a chargeback risk.
Walgreens expects the EDI 855 Purchase Order Acknowledgment within 1 business day of the PO date. A late or missing 855 is treated as a compliance event and can affect your scorecard with Walgreens' merchant team. SBSA auto-fires the 855 within minutes of PO receipt — regardless of time of day or weekend receipt — so the 1-business-day window is never at risk.
Yes — and as an Intuit Silver Partner for both QuickBooks Online and QuickBooks Enterprise, SBSA Technology has the certification and experience to do it properly. Walgreens purchase orders flow in as QuickBooks Sales Orders automatically. When you ship, the ASN is generated and the QuickBooks invoice is created simultaneously. Payment remittance from Walgreens is auto-applied to open invoices. The entire order-to-cash cycle runs without manual entry.
A shipment arriving at a Walgreens DC without a pre-transmitted ASN — or with an ASN that arrives after the physical goods — is treated as a compliance failure and triggers a chargeback. In some cases, the shipment may be refused. SBSA transmits the EDI 856 ASN automatically the moment your shipment leaves your facility, with all required carrier and packaging fields populated. The ASN always leads the truck.
Walgreens' brick-and-mortar replenishment and its e-commerce fulfillment channels may operate as separate EDI trading partners or use the same connection with different PO routing. SBSA can configure both channels simultaneously — using the same ERP mapping layer where possible to minimize setup effort — and monitors compliance separately for each channel's requirements.
No. SBSA Technology manages the full integration — from initial Walgreens trading partner setup to ERP mapping, testing, go-live, and ongoing 24/7 monitoring. Your team confirms business details (fulfillment paths, ERP credentials, item master data) and we handle everything technical. Most clients have zero ongoing EDI administration tasks once the integration is live.
