Hey there, good that you activate package products in free version. But its a piece of irony to do not offer the option adding quantities to products from "package product". for example: System 2 exists out of product 1 and product 2 --> now activating package product for System 2. --> System 2 consists out of 2x product 1 and 3x product 3. Thats not possible. Hope that will be upgraded soon! Its a basic structure in our rental company. Thank you!
