You can pass your order information into Delivery Manager from an OMS (Order Management System) or WMS (Warehouse Management System), in any of the following ways:
Using a connector with a pre-built interface to Delivery Manager, e.g. the Metapack interface to Salesforce's OMS or the EPI for Manhattan's WMOS. If you are interested in using one of these connectors, click here in the first instance to create a case with Metapack.
By importing an orders file through the Delivery Manager GUI.
