When processing orders in bulk via the Vendor Portal, you'll need to Export Orders and populate courier codes manually, before Importing Orders back to the Portal.
If the courier in question is integrated with Reachdesk, you'll find the corresponding codes in the attached document. Providing the courier code and the tracking number will ensure Reachdesk tracks the status of the order automatically.
If the courier is not integrated with Reachdesk, please leave this column blank in your CSV. In this case, you'll need to manually "Mark Order as Delivered" within the Portal once the shipment is delivered.
Note: Please always include the Tracking Numbers. If the courier is not integrated with Reachdesk, please leave the Courier Code column blank and only add the Tracking Number to the CSV.
