When listing car/vehicle parts, and accessories it is wise to add Compatibilities to ensure a problem-free customer purchasing experience. Compatibilities allow you to specify what vehicles your products are compatible with. In order to add Compatibilities in Ad-Lister, you must select an eBay category that supports compatibilities.

eBay categories that have a [C] next to their name can have compatibilities.
Using Ad-Lister you can add compatibilities to your listings in the following way:
You can update the compatibility list manually from the Compatibility editor available on the products
Click on the C in the Status column to get onto the Compatibility page. There you can use the Edit or Edit in table function to update the compatibilities.
Update Compatibilities using KTYPES via CSV
You can download the product from Ad-Lister and then add the KTYPEs directly on to the CSV file and upload it back into Ad-Lister in order to update the compatibilities.
Update compatibilities from CSV- with the full compatibility list
You can add compatibilities the old way, by adding the names and values, types etc.
