ShipStation does not currently have a dedicated field to import/display your Value Added Tax (VAT) ID number on your packing slips.
To include your VAT ID on your packing slip, you will need to manually edit your packing slip's HTML to add this value.
You must be on a silver plan or higher to access and edit your packing slip templates.
Add a VAT ID to Packing Slips
Here's an example of adding this information to the header section of your packing slip template.
The VAT ID here is contained within the <td> tag that also includes the [Order #] field replacement:
<td align="right" class="label">VAT ID #</td>
Here is how it should look within your HTML code:
This will make it appear on the packing slip like this:
Excluding Duplicate Taxes
If your selling channel already includes VAT on either the item or order level, the Sales Tax field imported into ShipStation could be duplicating the taxed amount, thus causing the order total to be higher than it should be on a packing slip.
This is due to the order total including the taxes paid field in its total.
To compensate for this, use the field replacement [Amount paid] instead of [Order total] in the footer section of the packing slip.
Follow these steps to properly replace this value:
If you copied your default packing slip to make this change, be sure you assign the new packing slip template to your store so ShipStation uses the correct packing slip going forward.
