Distribution integration

Harbor Wholesale EDI integration and automation

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

Overview

Understanding Harbor Wholesale integration

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

Harbor Wholesale is a distributor to grocery and convenience retailers. Suppliers that trade with Harbor Wholesale electronically exchange documents such as the 850 purchase order, 855 purchase order acknowledgment, 860 purchase order change, 856 ship notice/manifest and 810 invoice. 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 5010. Order types include ship to distribution center and traceability items. 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. Harbor Wholesale sets its own requirements and can change them, so treat your account contact and current guide as the final word.
