Thanks for using our plugin!
The first thing you have to do is set up your suppliers. Go to the supplier tab and add all your suppliers.
Assign the newly created suppliers to your products. Do do this in the product edit page under the order and inventory manager tab or if it is a variant in the variant tab for that variant.
While you are here you also fill out all other information for your products.
If you have many products we highly recommend that you export all your products and import all new data for them. Further down you find more information about this topic under “How do I export and import OIMWC data?”.
You also want to take a look at the settings page to configure the plugin to work as you want it to.
