Hi Oscar,

Thank you for contacting WPClever Support Forum.

For your information: 

• In the free version of our plugin, only simple and subscription products can be searched and added. 
• Instead, free users can now add unlimited products as they prefer. 
• Variable products and variations are only available in the Premium version.

Note: Some types of subscription products are not fully compatible with our plugin as well. We can offer customization service to make it work if you are a Premium user and provide us with access to the admin area.

In case you need further instructions, kindly refer to this online documentation: https://doc.wpclever.net/.

Best regards.
