Custom PO numbers in your QuickBooks Online store can be imported into Descartes ShipRush Web.
Note: The imported PO number appears as an Alternate Number in Descartes ShipRush Web. To merge it into the reference, use this value: %AlternativeOrderNum%. To merge it into a packing list, use this value: @Order.AlternativeOrderNumber.
Login to your QuickBooks Online account.
Open an Invoice or Sales Order. Click the 'cog' icon in the upper right corner.
Click Add another field. Assign the new field with this exact name (without quotation marks): "P.O. Number".
An example of the field as it appears on your Invoice/Sales Order screen is shown below. Enter your PO number into this field.
The contents of the P.O. Number field will flow automatically into Descartes ShipRush Web under the Alt # field in Order Details. This can be mapped to the Reference or PO field on the Shipping screen using Shipment defaults.
