Hi Phil,
If I understand “perks” correctly then you need to create a standard WooCommerce variable product and add a variation for each “perk”. As our plugin doesn’t create any “special” product types and instead uses standard WooCommerce products, you could, for example, add “perk” attribute and create “Premium – Light Package”, “Exclusive – Light Package” etc. variations from it. Then you would just mark this variable product as “crowdfunding”. Hope you get the idea. Please let me know if you have any questions.
