Woocommerce related questions

Hi,

1. Couldn’t find how user can upgrade listing package. For example if I have basic and premium listing packages. User selects basic when adds listing but decides that wants to upgrade to premium later. How is it done?
2. If user buys e.g. 1 year basic package, will it be re-newed automatically after a year or does he need to buy it again? If it doesn’t re-new it automatically, is there a way to do it or does it need customization?
3. Do I need to activate “My products” somewhere to enable users to add their own products to sell via their listing? Cannot see “My Products” when signing in to profile.
   1. In addition, Is Woocommerce Vendor only way to get my cut of the products user sells via listing?

Thanks again for your great support,

Mika
