Complete guide to reading and processing Lowe's EDI files (850, 856, 810, 997). Learn ASN requirements, compliance penalties, and how to avoid chargebacks.
Lowe's enforces stringent EDI compliance requirements for all vendors. Missing or late ASNs, inaccurate labeling, late deliveries, and incomplete EDI transmissions result in chargebacks. Understanding how to read and process Lowe's EDI files correctly is essential to avoid costly penalties.
Lowe's expects the 856 ASN the moment a shipment leaves—not after. Late ASNs result in immediate chargebacks, regardless of whose fault it is.
Lowe's requires vendors to support these core EDI transactions:
The EDI 850 Purchase Order from Lowe's contains everything you need to fulfill the order: quantities, pricing, ship-to locations, and delivery dates.

Lowe's requires GS1-128 barcode labels on all cartons. The SSCC-18 (Serial Shipping Container Code) on the physical label must exactly match the MAN*GM segment in your 856 ASN.
The EDI 810 Invoice must reference the original PO number and match the quantities from your 856 ASN. Lowe's requires compliance data (e.g., TSCA Title VI certification for wood products) in invoices.

Lowe's requires compliance data in your invoices. For wood products, include TSCA Title VI certification. Missing compliance data results in invoice rejection.
The 997 is a mandatory functional acknowledgment. Lowe's will send you a 997 to confirm receipt of your 856 ASN and 810 Invoice. You must also send a 997 back to Lowe's when you receive their 850 Purchase Orders.
If you skip sending 997s, Lowe's sees your system as non-responsive, which can lead to compliance violations and account holds.
Error: ASN not sent before truck arrival
Solution: Configure your ERP or 3PL to trigger the 856 automatically the moment the shipment leaves. Use automated EDI workflows.
Error: ASN says 12 cartons, but labels scan as 10
Solution: Verify carton counts before sending ASN. Implement barcode scanning at your warehouse to catch errors before shipping.
Error: GS1-128 label doesn't match MAN*GM segment in ASN
Solution: Use GS1-compliant label printing software. Validate SSCC-18 check digit using MOD 10 algorithm before printing.
Error: Invoice missing TSCA Title VI or other required certifications
Solution: Add compliance data fields to your invoice template. Consult Lowe's EDI specification guide for required certifications by product category.
Error: Failure to send 997s after receiving 850 POs
Solution: Enable automatic 997 generation in your EDI software for all inbound transactions.

PlainEDI currently converts EDI files to CSV/Excel (reading inbound files like 850 POs). For creating outbound EDI files (856 ASNs, 810 Invoices), you'll need EDI translation software or a VAN provider that supports EDI generation from CSV/Excel templates.
