Walmart EDI — What SBSA Handles

Select your supplier type to see the workflow

1
850 Purchase Order received

Auto-ingested from Walmart Retail Link or EDI transmission and converted to sales order in your ERP.

2
855 Acknowledgment fired within 24hrs

Auto-generated and transmitted — confirms item acceptance, quantities, and ship dates at line level.

3
753 Routing Request sent

Carrier routing request auto-triggered for all collect shipments — Walmart returns 754 Routing Instructions.

4
856 ASN at time of shipment

GS1-128 carton labels generated and validated; ASN transmitted before carrier pickup — OTIF compliance locked.

5
810 Invoice auto-generated

One invoice per PO. Reconciled against 820 payment remittance from Walmart automatically.

1
850 DSV Purchase Order received

Order includes customer ship-to address and Walmart-branded packing slip requirements — auto-parsed.

2
855 Acknowledgment — 24hr SLA

Line-level acceptance or rejection confirmed. Unavailable items flagged; no silent cancellations.

3
Walmart-branded packing slip generated

Auto-produced from order data — customer never sees your company name; Walmart branding applied.

4
856 ASN before carrier pickup

Includes tracking number, ship date, carrier, and package-level detail — late ASN triggers chargeback.

5
810 Invoice per DSV PO

Matched back to the original 850; discrepancies surfaced before submission.

1
850 Import PO received

Includes vendor-specific import requirements, port routing, and volume-level detail — auto-mapped to your ERP.

2
855 Acknowledgment with lead time

Acknowledges ship window with manufacturing lead time built in — critical for import compliance scoring.

3
856 ASN at container load

Container-level ASN generated with pallet, carton, and item hierarchy — customs-ready data included.

4
810 Invoice per import PO

Auto-generated against confirmed ship quantities; commercial invoice data cross-validated.

5
Compliance monitoring ongoing

OTIF, fill rate, and scorecard metrics tracked in real time through SBSA's monitoring dashboard.

Which Walmart Supplier Path Are You?

Walmart operates four distinct supplier models, each with its own EDI requirements, OTIF targets, and routing rules. SBSA handles all four — often simultaneously for the same vendor.

Domestic Distribution Center

You ship full pallets or truckloads to a Walmart DC. Routing requests (753) are required for collect shipments; on-time delivery to the DC counts toward your OTIF score.

DC Supplier

Direct Store Delivery

You deliver directly to individual Walmart store locations. Store-level EDI and delivery confirmation requirements differ from DC shipments and require separate workflow configuration.

DSD Vendor

Drop Ship Vendor (Walmart.com)

You fulfill Walmart.com orders directly to the end customer under Walmart's brand. Every parcel must carry a Walmart-branded packing slip; no supplier branding is permitted.

DSV / Drop Ship

Direct Import Supplier

You manufacture overseas and ship directly to Walmart's import DCs. Longer lead times require early 855 acknowledgment and container-level ASNs with customs-ready data.

Direct Import
3% OTIF penalty of cost of goods — avoided by SBSA's automated ASN and routing workflows
24hr Maximum window for EDI 855 PO Acknowledgment — auto-fired by SBSA within minutes
6+ Core EDI transactions managed: 850, 855, 856, 810, 753, 754 — plus optional 820, 860, 852
100% GS1-128 carton label validation against ASN contents before every shipment leaves your facility

How Your EDI Reaches Walmart

Walmart supports three EDI transmission protocols. SBSA Technology manages full setup, testing, and monitoring for all three — you choose what fits your infrastructure.

SFTP

Secure File Transfer

SFTP provides a file-based EDI connection via a secure FTP server. Walmart maintains an SFTP endpoint for suppliers who cannot implement AS2 or prefer batch file transmission workflows.

  • Encryption: SSH-based secure file transfer
  • Polling: SBSA polls at configurable intervals (typically every 15 min)
  • Use case: Suited to batch-oriented ERP systems or lower order volumes
  • Acknowledgment: SFTP acknowledgment file returned per batch
  • Setup: SBSA configures credentials and folder mappings with Walmart

VAN

Value-Added Network

A VAN (Value-Added Network) acts as a mailbox intermediary between you and Walmart. Useful if you already have a VAN relationship for other trading partners — your documents route through the same hub.

  • Providers: Sterling Commerce, SPS Commerce, TrueCommerce, and others
  • Billing: Per-kilocharacter or per-document pricing applies
  • Consolidation: Single VAN connection for multiple retail partners
  • Reliability: Store-and-forward ensures no document loss during downtime
  • Setup: SBSA coordinates your VAN mailbox enrollment with Walmart

Walmart EDI Integration EDI Transaction Set

SBSA Technology supports core and supplemental Walmart EDI Integration EDI documents. Critical transactions are highlighted because they carry the highest compliance risk when transmitted incorrectly or late.

850

Purchase Order

Walmart's order for goods — inbound to your system. Contains item UPCs, quantities, ship-to DC or customer address for DSV, and delivery window. Auto-converts to sales order in your ERP.

Inbound
855

PO Acknowledgment

Confirms acceptance of each PO line — quantities, ship dates, and any substitutions. Must be sent within 24 hours of PO receipt. Missing or late 855s count toward your compliance scorecard.

Outbound Must respond within 24 hours of PO receipt
856

Advance Ship Notice

Sent at time of carrier pickup. Contains shipment hierarchy: pallet → carton → item. Must include SSCC-18 barcodes matching GS1-128 labels. Late or missing ASNs trigger OTIF fines.

Outbound Transmit before goods arrive at DC — chargeback risk
810

Invoice

One invoice per PO. Must match the 850 quantities exactly — over-invoicing or invoicing cancelled lines triggers payment disputes. SBSA auto-generates against confirmed ship data.

Outbound
997

Functional Acknowledgment

Confirms syntactic validity of every transmitted document. SBSA monitors all 997 responses and surfaces rejections before they escalate to compliance issues.

Outbound
820

Payment Remittance

Walmart's payment and remittance advice — auto-reconciles against your open invoices when received, flagging any short-payments or deductions for review.

Inbound
860

PO Change Request

Walmart-initiated modifications to an accepted PO — quantity changes, delivery window adjustments, or cancellations at line level. Changes auto-applied to your open sales order.

Inbound
753

Routing Request

Sent to Walmart to request carrier routing instructions for collect shipments. Must be submitted before scheduling your carrier. Walmart responds with the 754 — routing instructions you must follow exactly.

Outbound Required for all collect shipments to Walmart DCs
754

Routing Instructions

Walmart's response to your 753 — specifies the carrier, pickup window, and delivery appointment. Deviating from the 754 instructions counts as an OTIF violation even if you arrive on time.

Inbound You must use the exact carrier Walmart specifies
852

Product Activity Data

Point-of-sale and inventory data from Walmart stores for your items — enables demand-driven replenishment and helps you anticipate Walmart's next PO before it arrives.

Inbound
824

Application Advice

Walmart's application-level response to your transactions — reports acceptance, rejection, or error conditions at the business-data level beyond what a 997 functional acknowledgment covers.

Inbound
180

Return Merchandise

Walmart return authorization and merchandise return documents for supplier-funded returns programs — auto-matched back to original PO and invoice for claims reconciliation.

Inbound

Connect Walmart EDI to Your Business System

SBSA bridges your Walmart EDI program directly to the back-office system you already use — eliminating rekeying, reducing errors, and keeping your order-to-cash cycle moving without manual intervention.

QuickBooks Online – Intuit Silver Partner

SBSA's certified QuickBooks Online integration maps every Walmart 850 PO directly to a QBO Sales Order — items, quantities, ship-to addresses, and pricing pre-populated from EDI data. Invoices auto-generate from ship confirmation and sync to QBO instantly.

QuickBooks Enterprise - Intuit Silver Partner

For suppliers running QuickBooks Enterprise, SBSA provides a deeper integration layer — including warehouse location mapping, advanced inventory, and bin-level pick-and-pack data flowing back into your EDI ASN automatically.

Netsuite

Bidirectional integration: 850 POs create sales orders in NetSuite automatically; ship confirmations and invoices flow back to Walmart as EDI 856 and 810.

SAP (ECC / S/4HANA)

Full SAP integration via IDocs or direct API. Maps Walmart's EDI segments to SAP order management, warehouse management, and FI invoice processing.

Microsoft Dynamics 365

Native D365 integration for purchase order receipt, warehouse pick and ship confirmation, and automated invoice creation from confirmed shipments.

Oracle ERP Cloud

Integration with Oracle Fusion Order Management and Inventory. SBSA maps Walmart 850s to Oracle sales orders and returns 856/810 from Oracle confirmations.

Shopify / WMS Platforms

For brands using Shopify as their OMS or third-party WMS platforms (ShipBob, 3PL Central, Logiwa, etc.), SBSA provides API-based integrations that route Walmart orders into your fulfillment workflow.

Custom & Legacy Systems

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.

753 Routing Request automatically triggered for all collect shipments — carrier confirmed before pick begins

854 instructions received and applied to shipment record — carrier deviation alerts prevent OTIF violations

856 ASN generated and transmitted at moment of carrier pickup confirmation — never after

GS1-128 carton labels auto-generated and validated against ASN contents before dispatch

SSCC-18 barcodes generated per carton and per pallet — full hierarchy encoded in ASN

Walmart-branded packing slips auto-produced for all DSV orders — customer never sees your brand

810 invoice auto-generated per PO from confirmed ship quantities — one invoice, zero duplicates

Short-ship lines reflected in 855 with revised dates — no silent cancellations that violate OTIF

820 remittance auto-reconciled — deductions and short-pays surfaced for dispute review within hours

Walmart EDI FAQ

Common questions from suppliers beginning their Walmart EDI compliance journey — from OTIF penalties to QuickBooks integration.

Walmart's On-Time In-Full (OTIF) program fines suppliers 3% of the cost of goods for every order that arrives outside the delivery window or falls short on quantity. The fine applies per purchase order, not per item — a single non-compliant truckload can run into thousands of dollars. SBSA automates your 753 Routing Request, 856 ASN transmission, and GS1-128 label validation to eliminate the most common OTIF triggers before a shipment ever leaves your facility.

Walmart suppliers operate through one of four models: (1) Domestic Supplier shipping to Walmart Distribution Centers — the standard wholesale model, subject to full OTIF requirements; (2) Direct Store Delivery (DSD) vendor, delivering to individual store locations with store-level ASNs; (3) Drop Ship Vendor (DSV) fulfilling Walmart.com orders directly to end customers, where Walmart-branded packing slips are mandatory; or (4) Direct Import supplier, shipping from overseas factories directly to Walmart's import DCs. SBSA handles all four, and many suppliers operate under more than one model simultaneously.

An ASN that arrives at Walmart's systems after the physical goods reach the DC is treated as a compliance failure and may trigger a chargeback equivalent to the OTIF fine. Walmart's receiving systems expect to find an ASN on file before your trailer docks. SBSA transmits the 856 ASN the moment your carrier confirms pickup — not when the paperwork is processed later — so the ASN is always in Walmart's system ahead of the freight.

The 753 Routing Request is required for all collect (Walmart-paid freight) shipments to Walmart Distribution Centers. Walmart responds with a 754 Routing Instructions document that specifies the exact carrier and pickup window you must use. Deviating from the 754's instructions — even if your shipment arrives on time — counts as an OTIF violation. SBSA auto-fires the 753 the moment a PO is accepted and applies the 754 routing to your shipment record automatically.

Yes — as an Intuit Silver Partner, SBSA provides certified integrations with both QuickBooks Online and QuickBooks Enterprise. Walmart POs flow directly into QuickBooks as sales orders, invoices auto-generate from confirmed ship data, and 820 payment remittances reconcile against open invoices automatically. For QuickBooks Enterprise specifically, SBSA also supports advanced inventory, bin-level tracking, and multi-warehouse configurations that feed directly into your ASN data — eliminating the manual steps that cause ASN errors.

Yes. Many SBSA clients run both a retail supplier program (shipping to Walmart DCs) and a DSV program (shipping direct-to-consumer for Walmart.com) simultaneously. Retail and DSV operate as separate EDI trading relationships with different transaction requirements — retail requires 753/754 routing and pallet-level ASNs, while DSV requires parcel-level ASNs and Walmart-branded packing slips. SBSA manages both programs through a single integration layer with separate compliance monitoring for each, sharing your ERP mapping to minimise setup cost.

Walmart supports AS2 (their preferred method — direct, encrypted, real-time), SFTP (secure file transfer for batch workflows), and VAN (Value-Added Network, useful if you already use a VAN hub for other retail partners). AS2 is recommended for OTIF-sensitive workflows because it provides near-real-time transmission with MDN delivery confirmation, which is critical when ASN timing directly affects your compliance score. SBSA sets up, tests, and monitors all three protocols on your behalf.
