This add-on allows you to choose which products on your site should earn commission for your affiliates. Although AffiliateWP allows you to disable commission on products (for supported integrations), it can be cumbersome to disable commission on every single one, especially if you have hundreds of products.
Installing and activating this plugin will straight away block all products from generating a commission. Then you simply need to enter the product IDs of the products that should generate a commission in the field provided.
