Inactive Items and IPI

I just started up my online store. I have been kind of delayed sending in my first shipment. But I have already added a majority of my items to my inventory. They are listed as inactive. I haven’t confirmed a shipment or anything. I still have to print labels. Will this affect my ipi at all? Would it make more sense to just delete my listings until I’m actually ready to ship? Or would this create other issues? Thanks in advance for any help!
