How can I get a report on what my store sold vs my website?

My store will have a brick-and-mortar storefront as well as sell online, through consignment kiosks, and at craft shows. I know I can set all of these up as different locations, but fundamentally, everything comes from the same inventory. I can’t break out my inventory by different sites. How can I tell where my sale is coming from?

Thank you for your help!
