Your shipment spreadsheet → a Walmart-valid 856 ASN
Upload the export from your warehouse or 3PL, map the columns once, and download ASNs for every open PO — validated against Walmart's spec before you send, with every error explained in plain English.
What it will do
| Step | What happens |
|---|---|
| 1. Upload | Your shipment spreadsheet (CSV/XLSX) — or our template. Parsed in your browser. |
| 2. Map once | Point your columns (PO number, UPC, qty, cartons, SSCC) at the right fields. Saved for next time. |
| 3. Generate | One valid 856 per PO — correct pallet→carton→item hierarchy, SSCC-18 check digits verified. |
| 4. Validate | Every issue in plain English: “Walmart requires a carton-level; your file has pallet→item with no carton.” |
| 5. Send | Download and upload to WebEDI in Retail Link (or your VAN). We show you exactly where. |
Why not just use WebEDI's forms, or a full EDI provider?
You can key ASNs field-by-field into WebEDI for free — many suppliers do, until volume or a mis-keyed carton count bites. Full-service providers (SPS, TrueCommerce) automate everything from ~$120–300/month plus setup fees, which makes sense at hundreds of documents a month. FluentEDI is for the supplier in between: flat $39/month, unlimited documents, no sales call, working from the spreadsheet your warehouse already produces.
Honest scope
v1 generates and validates the files; you upload them to Walmart yourself (WebEDI accepts file uploads — we walk you through it). Direct AS2 transmission is on the roadmap. One ASN per PO at launch; if you consolidate many POs onto one truck, tell us — it moves the multi-PO ASN feature up the list.
