ApeksOPS works with your existing products and product variations in WooCommerce.  It will, however, only recognize those that have the “Manage stock?” tick box ticked on the WooCommerce “Edit Product” page. If you have not done so previously, tick “Manage stock?” for each product. 

NOTE: If you don’t keep stock of products but still want to use ApeksOPS for purchasing, turn on the option to allow backorders, so that products will still appear in your store.

NOTE 2: If you have variable products, each of the variations for each product must have “Manage Stock” ticked also.
