Distribution integration

Grainger EDI integration and automation

A guide for suppliers connecting with Grainger, covering the documents exchanged, the main program rules, testing and ERP integration.

Overview

Understanding Grainger integration

Who this is for: Suppliers that sell to Grainger, and the EDI, logistics and finance teams that support them.

Grainger is a distributor of maintenance, repair and operating supplies. Suppliers that trade with Grainger electronically exchange documents such as the 850 purchase order, 855 purchase order acknowledgment, 856 ship notice/manifest, 810 invoice and 997 functional acknowledgment. This page summarizes how that exchange works from the supplier's side, so your team can scope the work before mapping starts.

The program uses X12 4010. Order types include replenishment and drop-ship. Each order type can change which documents apply and how locations, labels and invoices are handled, so it helps to confirm which ones you will supply before you build anything.

Most of the effort goes into keeping your ERP, warehouse and shipping data consistent with what each document says. Ship notices, labels and invoices need to agree with the original order, and any rule that applies only to one order type needs its own handling in your maps. Grainger sets its own requirements and can change them, so treat your account contact and current guide as the final word.

Program summary

What Grainger asks of suppliers

A summary in ECOM's own words. Requirements vary by program and change over time, so confirm the details with Grainger during setup.

Ship notices

  • A ship notice is required for every shipment, including direct-to-customer ones.
  • Each shipment gets its own ship notice for each destination and supplier number. One notice can cover several purchase orders, and each trailer needs its own.
  • Ship notices go at time of shipment, in real time rather than in batches.

Invoices and payment

  • Each invoice bills one purchase order.

Testing

  • Each business unit is set up as its own EDI relationship, and every document is tested against each test order.

Challenges

Common integration challenges

  • Keeping order types apart

    Different order types can need different maps, locations and labels, so identify each Grainger order type before mapping.

  • Documents that agree

    Ship notices, labels and invoices need to match the order and each other, or they can cause receiving and payment problems.

  • Changes over time

    Requirements change. Keep a process for picking up new Grainger rules and retesting affected documents.
