As we said in the add listing package guide, you might want to charge your user when he submits a listing. In order to do that, you need to create a listing product to combine with a listing package.
First, be sure you've installed Woocommerce plugin. Then go to Dashboard → Products → Add New and create a new product.
Be sure you select "listing product" from the product type select.
Here we go! Now you are ready to charge for your package!
Set the price of your package, just as you would do with a normal product type.
Now return to your existing listing package (Dashboard → Package Manager) and click on the one you want to add the listing product just created.
In the product label, choose the product just created.
