Home Depot EDI Requirements: How to Become Compliant

Home Depot splits its supplier base across three programs — stock, special order, and dropship COM — and all three ride the same EDI documents with different rules layered on top. Understanding which program each order belongs to is the first compliance skill a Home Depot supplier needs, because the document that leaves your system must follow the rules of the program that produced it.

Three programs, one document set

Stock replenishes stores and DCs. Special order (SO) captures a customer's configured purchase at the Pro desk. Dropship COM ships directly to the customer's address. The X12 4010 documents are identical in shape; what changes is the validation each program applies. A special order, for instance, carries customer detail on the 850 that must round-trip intact onto the 856 — lose it in translation and the store can't connect the delivery to the sale. Certified maps that know the program rules turn this from tribal knowledge into configuration.

Reading a Home Depot purchase order

Two things distinguish Home Depot's 850 from a generic retail PO:

• SDQ segments. Multi-store quantities arrive packed into SDQ blocks on a single line. Before anything ships, your system explodes them into store-level allocations — a step that must be automatic, because doing it by hand at Home Depot's order volume is how allocation errors are born.
• Program context. Stock, SO, and dropship orders each carry the detail their downstream documents will need. Capture it at order receipt; you cannot reconstruct it later.

The 855 acknowledgment, 810 invoice, and 997 functional acknowledgments round out the chain in both directions.

Where THD supplier compliance bites

Home Depot's THD supplier compliance program grades ASN and label accuracy, and the 856 ship notice is where suppliers earn or lose their scorecard:

1. UCC-128 labels are validated against MAN segments. The serial on the physical carton label and the serial in the ASN must match — generate both from the same carton data or they will diverge.
2. Store-direct and DC shipments carry different hierarchy rules. The HL structure that passes for one flow fails for the other, so the map has to branch on destination type rather than apply one shape everywhere.

Because receiving scans freight against the ASN, an accurate document is not paperwork — it is the thing that gets your truck unloaded without deductions.

The acknowledgment rhythm

Order volume across three programs means the quiet plumbing matters. Every inbound 850 should be answered by a 997 within minutes and processed into your system the same day — a PO that waits in a mailbox until someone checks it is aging against ship windows the whole time. Outbound, watch for the acknowledgments Home Depot returns on your ASNs and invoices: a missing 997 is the earliest possible signal that a document never arrived, and catching it the same hour turns a potential compliance event into a retransmission nobody remembers. This is monitoring software's job, not a person's; the ack trail only works if it is watched continuously.

The path to a working connection

Setup runs in four moves: complete Home Depot's vendor onboarding, connect your ERP or commerce platform (Dynamics 365 Business Central, Shopify for dropship-heavy suppliers, or 30+ others), build the item and store cross-references, then certify each document type through testing. With prebuilt Home Depot maps the EDI portion typically lands in 1–3 days; the vendor-side paperwork is what sets the calendar.

On cost, EDISQ charges for documents and nothing else: 25 free every month, then a rate that starts at $0.50 and falls to $0.10 per document as monthly volume climbs, applied marginally per tier. Connectivity over AS2, SFTP, or VAN is bundled in, there are no mapping or setup charges, and the $100/month Production minimum applies in full to usage — details on the pricing page. Three Home Depot programs, one connection, one predictable bill.
