Managed EDI for Zappos suppliers
Zappos EDI. Connect the dispatch to every carton.
Selling wholesale merchandise to Zappos means keeping orders, routing references and shipment data aligned. Roundhouse performs the EDI processing, from incoming purchase orders to ASNs, GS1-128 label files and approved invoices.
Let’s talk about your EDI
What is Zappos EDI?
Zappos EDI exchanges wholesale purchase orders, revisions, shipment notices and invoices with merchandise vendors. Roundhouse processes these documents using your approved information. This service concerns supplier orders to Zappos, not operating a consumer marketplace seller account.
The ASN does not replace routing approval.
Zappos assigns a dispatch number through its routing process and requires that reference in the ASN. We connect the approved dispatch information with the shipment record. Your logistics team arranges the physical movement and routing approval; we prepare the electronic notice from the confirmed details.
Zappos EDI documents and processing.
Zappos’s vendor guide identifies the core documents and labels below and lists the 855 separately as optional. We confirm current account instructions during setup.
| Code / format | Document | What we handle |
|---|---|---|
| 850 | Purchase Order | Translate the wholesale order and supplier references. |
| 860 | Purchase Order Change Request | Reconcile approved revisions before shipping. |
| 856 | Advance Ship Notice | Include the assigned dispatch reference and carton information. |
| GS1-128 | Shipping label | Prepare carton identifiers aligned with the ASN. |
| 810 | Invoice | Prepare approved shipped quantities and billing references. |
| 997 | Functional Acknowledgment | Check technical responses and reported errors. |
| 855 — optional | Purchase Order Acknowledgment | Prepare responses when used for the account. |
Carry order revisions into shipping.
Zappos uses 860 documents for purchase-order changes. We reconcile revised information before preparing the shipment and invoice. An optional 855 can communicate an account-supported response; it is not automatically treated as a mandatory step for every order.
Match the carton barcode to the contents.
We prepare GS1-128 labels and ASN carton information from the same approved packing data. A label identifies a shipping container; the ASN describes the shipment and its merchandise. Correct item references, quantities and container identifiers help the receiving process work as intended.
Prepare the invoice and follow the response.
We use approved shipped quantities and PO references when preparing billing, then review technical acknowledgments and exceptions. Setup includes the current maps, testing and a handover for open orders. Your staff supplies packing facts and approvals; Roundhouse does the EDI entry and processing.
