If there is a product that isn't synching to Finale, it may not have a product ID associated with it. This is usually in cases such as discounts, or program fees. They are not tangible items, so they won't be pulled from inventory. This affects the entire order, and the full order will not be processed as shipped, even though the order has already been shipped from ShipStation.

For these types of "products" you will want to create a Wild Card SKU.

Go to Integrations

Under ShipStation click on Actions Under Pull Sales to Finale

Click on Edit Task Configuration

Scroll down to Wildcard SKU Options

Click on Add Wildcard Lookup

Enter the Product ID and title for the Product

Under the Actions drop down box, choose Do Not Import

(this will tell Finale not to pull this item in as inventory)

Scroll back to the top of the back and click Save Changes on the upper left hand side of the page
