Wegmans EDI requirements for suppliers

What Wegmans publishes for suppliers about EDI, which documents each flow uses, how purchase order numbers work, how certification runs on its third-party testing site, and who to contact.

Overview

Understanding Wegmans integration

Who this is for: Food and consumer goods suppliers shipping to Wegmans warehouses and stores, including Quick Response, direct store delivery and vendor-managed inventory suppliers.

Wegmans publishes a short, practical EDI page in the For Our Suppliers section of its website. Rather than one document set for everyone, it lists the transactions by flow. Warehouse suppliers use grocery (UCS) documents: the 875 purchase order, 856 ship notice and 880 invoice. Quick Response and direct store delivery suppliers use X12 documents: the 850, 856 and 810. Vendor-managed inventory suppliers to the warehouse exchange the 852, 855, 856 and 880.

Two details on the page matter for mapping. Wegmans purchase order numbers carry the week number in their first two digits, and the remaining four digits come from a sequence assigned to each vendor. Vendor-managed inventory suppliers receive sales and promotional logic every Monday on an 852, which Wegmans encourages in place of faxed data.

Certification runs on a third-party testing website for Wegmans after Wegmans approves you and your item data is aligned. Wegmans also asks suppliers to publish product data through the 1WorldSync data pool. This guide records what the pages say and when we checked, and lists what we could not confirm.

Requirements at a glance

Document by document

What each Wegmans document needs

For each document: what it does for you as the supplier, what Wegmans's own documents say about it (with the source and its date), and general EDI practice that helps, labelled as such. Your Wegmans mapping guide for your version is the final word on fields and codes.

875

Purchase Order (875 warehouse, 850 Quick Response and DSD)

You receive

Warehouse orders arrive as a grocery 875; Quick Response and DSD orders arrive as an X12 850. Both carry Wegmans' purchase order number structure.

What Wegmans states

How the 875 works in X12

856

Ship Notice/Manifest

You send

Every Wegmans flow lists the 856, including DSD, which Wegmans labels UCC-128.

What Wegmans states

General EDI practice

  • Build the 856 from carton-level pack data so it matches the labels on the delivery.

880

Invoice (880 warehouse and VMI, 810 Quick Response and DSD)

You send

Warehouse and VMI invoices go back as a grocery 880; Quick Response and DSD invoices as an X12 810.

What Wegmans states

General EDI practice

  • Invoice from the same cost records you maintain in W-Buy, so costs agree.

Checklist

Wegmans EDI readiness checklist

  1. Confirm which flow you are in: warehouse, Quick Response, DSD or VMI warehouse.
  2. Align UPC, GTIN, cost, case and pack in 1WorldSync before certification.
  3. Map both UCS and X12 documents if you supply more than one flow.
  4. Read the week number and vendor sequence in every purchase order number.
  5. Email Wegmans' B2B EDI team with questions before you start NCM testing.
  6. If you are a VMI supplier, load the Monday 852 instead of faxed sales data.
  7. Set up ACH payments with Wegmans' EFT team.

Common mistakes with Wegmans EDI

Purchase order numbers outside your sequence

The last four digits must fit the sequence Wegmans assigned to you, or EDI issues follow.

Challenges

Common integration challenges

  • Two formats by flow

    Warehouse suppliers use grocery 875 and 880 documents, while Quick Response and DSD use X12 850 and 810, so many suppliers need both.

  • Purchase order number rule

    The first two digits are the week number and the last four must fit the vendor's assigned sequence, or EDI issues follow.

  • Data alignment first

    UPC, GTIN, cost, case and pack must align before certification starts, through the 1WorldSync data pool.
