MRO Product Manufacturers
Manufacturers of maintenance, repair, and operations products shipping to Grainger's DC network or direct to industrial end-customers. Typically high-volume with complex multi-SKU POs.
Grainger is one of the world's largest MRO distributors — 1.7M+ products, 300+ branches, and 30+ distribution centers across North America. SBSA Technology delivers full EDI compliance for all three Grainger fulfillment paths: Distribution Center, store, and direct ship to customer.

PO numbers beginning with 46 are from Grainger Industrial; 48 are from Grainger Sourcing. Handled the same way.
Must acknowledge within 1 business day of PO creation — missing this triggers compliance issues.
Grainger expects all orders to be shipped complete. Backordered items must not be cancelled.
Shipments arriving at Grainger DC without an ASN can be refused. One ASN per trailer for LTL.
One invoice per PO only. Credit, allowance, and freight-only invoices submitted on paper.
Ship-to address on the 850 will be a specific Grainger store rather than a distribution center.
All ASN, acknowledgment timing, and invoice rules are identical to DC shipments.
Grainger requires ship dates to be confirmed on a per-SKU basis — not just at order level.
All cartons must carry compliant GS1-128 labels with correct information matching the ASN.
Grainger-branded packing slip generated from the ASN must accompany every store shipment.
For direct ship orders, Grainger's 850 contains the end customer's delivery details — not a Grainger location.
All direct ship orders must include Grainger's branded packing slip generated from the ASN. Customer must not see your brand.
For UPS shipments, tracking number is mandatory in the 856 ASN. BOL or PRO number required for freight.
Do not send multiple ASNs for the same order. One ASN per shipment, one final destination, one supplier number.
Consumer-level order volume requires automation — SBSA connects Grainger's direct ship POs directly to your fulfillment system.
Whether you're a first-time Grainger supplier or scaling an existing relationship, SBSA Technology has a managed EDI path built for your business model.
Manufacturers of maintenance, repair, and operations products shipping to Grainger's DC network or direct to industrial end-customers. Typically high-volume with complex multi-SKU POs.
Distributors supplying Grainger stores and branches with safety, electrical, plumbing, or industrial supplies. Orders often specify branch-level destinations across multiple regions.
Suppliers who ship directly to Grainger's end-customers on Grainger's behalf. Must generate Grainger-branded packing slips and never reveal your identity on the shipment.
Niche suppliers in categories like power tools, safety equipment, fluid power, or HVAC. Often serve both Grainger Industrial (prefix 46) and Grainger Sourcing (prefix 48) simultaneously.
Suppliers also trading with Zoro.com — Grainger's online small-business brand. Zoro operates as a separate trading partner but SBSA can onboard both simultaneously with a shared ERP mapping layer.
Suppliers new to Grainger's supplier program completing the EDI compliance certification process. SBSA manages every step — from questionnaire to Grainger test environment sign-off to go-live.
Grainger supports AS2, SFTP, and VAN for EDI transmission. SBSA Technology handles complete setup, testing, and ongoing compliance monitoring for all three protocols.
Direct Protocol
Encrypted, point-to-point EDI transmission via AS2. Best for higher-volume Grainger suppliers who need fast, reliable direct connectivity with full delivery receipts and minimal per-transaction cost.
Secure File Transfer
Secure FTP-based document exchange — a practical option for suppliers with existing SFTP infrastructure or those transitioning to fully automated EDI. SBSA manages the SFTP server configuration and file monitoring.
Managed Network
Value-Added Network transmission for suppliers who prefer a fully managed, intermediary-based connection. SBSA acts as your complete EDI department — routing, translating, and monitoring all Grainger documents through the VAN.
SBSA Technology supports core and supplemental Grainger EDI Integration EDI documents. Critical transactions are highlighted because they carry the highest compliance risk when transmitted incorrectly or late.
Grainger's PO kicks off the fulfillment cycle. Specifies ship-to location (DC, store, or customer), items, quantities, ship dates, and pricing. PO# prefix (46 or 48) indicates Grainger vs. Grainger Sourcing.
InboundMust be sent within 1 business day of PO creation. Confirms ability to fulfill. Used to report quantity changes, ship date updates, or pricing discrepancies — all at the line item level.
Outbound ⚠ 1 business day deadlineSent as shipment leaves your facility. Incomplete or missing ASNs can result in refused shipments. Direct ship orders must trigger Grainger-branded packing slip generation from this document.
Outbound ⚠ Must send before physical arrival — refusal riskOne invoice per PO only. Standard EDI 810 for product invoices. Note: credit invoices, allowances, and freight-only invoices must be submitted on paper — not EDI.
Outbound ⚠ Credit/allowance/freight invoices are paper onlyConfirms syntactic validity of every transmitted document. SBSA monitors all 997 responses and surfaces rejections before they escalate.
OutboundGrainger's payment order and remittance advice — auto-reconciles against open invoices when transmitted.
InboundBuyer-initiated PO modifications. Updates are applied at the line item level — quantity, pricing, or delivery changes flagged and reflected in your system automatically.
InboundSales and inventory activity data shared with Grainger for demand planning and replenishment analysis — helps Grainger optimize stocking decisions for your products.
OutboundFree-form text message transaction used by Grainger for exception communications, special instructions, or non-standard order notes outside the structured EDI documents.
InboundSBSA Technology integrates Grainger EDI directly into your ERP — so every PO, acknowledgment, ASN, and invoice flows automatically without manual re-keying. We support the ERPs your team already uses.
Bidirectional integration: 850 POs create sales orders in NetSuite automatically; ship confirmations and invoices flow back to Grainger as EDI 856 and 810.
Full SAP integration via IDocs or direct API. Maps Grainger's EDI segments to SAP order management, warehouse management, and FI invoice processing.
Native D365 integration for purchase order receipt, warehouse pick and ship confirmation, and automated invoice creation from confirmed shipments.
Integration with Oracle Fusion Order Management and Inventory. SBSA maps Grainger's 850s to Oracle sales orders and returns 856/810 from Oracle confirmations.
SBSA connects Grainger EDI directly to QuickBooks Online via Intuit's API — translating Grainger POs into QBO sales orders, auto-generating invoices, and syncing payments without any manual data entry.
SBSA integrates Grainger EDI with QuickBooks Enterprise using QBXML or IIF file-based integration — fully automated PO-to-invoice workflows without disrupting your existing QBE setup or custom fields.
For brands using Shopify as their OMS or third-party WMS platforms (ShipBob, 3PL Central, Logiwa, etc.), SBSA provides API-based integrations that route Grainger's 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.
Grainger's ASN refusal policy is unforgiving — a refused shipment means the goods come back to you at your cost. SBSA Technology automates every compliance step so your Grainger relationship stays profitable and penalty-free.

Common questions from MRO suppliers beginning their Grainger EDI compliance journey.
Grainger suppliers ship to one of three destinations, specified in the EDI 850: (1) a Grainger Distribution Center — the standard wholesale model; (2) a Grainger branch store — same EDI requirements as DC shipments but delivered to a branch address; or (3) directly to the end customer as a direct ship order, where Grainger's branded packing slip is mandatory and the customer's address is embedded in the 850 PO. SBSA handles all three paths with destination-aware automation.
Grainger is strict on ASN compliance. Any shipment received at a Grainger location without an ASN, or with an ASN that arrives after the physical goods, can be refused entirely. A refused shipment means the goods are returned to you at your cost — one of the most expensive outcomes in supplier compliance. SBSA transmits the 856 ASN automatically the moment your shipment leaves your facility, preventing this scenario.
PO numbers beginning with 46 originate from Grainger Industrial Supply; those beginning with 48 are from Grainger Sourcing — a division that handles different categories of product supply. All business is conducted in exactly the same manner for both. The distinction will be clarified during your initial onboarding discussions with Grainger, and SBSA maps both PO prefixes identically in your EDI workflow.
Yes — despite requiring EDI for most document types, Grainger specifically requires three invoice types to be submitted on paper: credit invoices, allowances, and freight-only invoices. The mailing address varies by Grainger department and region, so early communication with your Grainger representative is strongly recommended. Your standard EDI 810 product invoices are transmitted electronically — only these three exceptions require paper.
Grainger expects all orders to be shipped complete. If you cannot fulfil certain items, you must reflect this in your EDI 855 PO Acknowledgment — updating the quantity, providing a revised ship date, or noting the availability issue at the item level. Crucially, Grainger states that backordered items should not be cancelled. Never enter a quantity of "0" on the ASN for an unfulfillable item — remove the line entirely instead, as a zero-quantity line is classified as a noncompliant data field.
Yes. Zoro.com is Grainger's online-only brand serving the small business market, and it operates as a separate EDI trading partner from Grainger Industrial. SBSA supports both simultaneously — we can set up Grainger and Zoro EDI connections in parallel, sharing the same ERP mapping layer to minimise setup effort and ongoing maintenance. Both are managed through SBSA's unified platform with separate compliance monitoring for each.
