Best way to sync inventory for different target audiences?

Hi everyone. I sell similar products but have two different Shopify stores for each audience. One is B2C, the other is B2B. The products are similar but vary in quality, pricing, packaging, branding etc. What's the best way to go about synching the same products together? For example, one product is offered as a bundle in my B2C store and also as a bundle in my B2B store. The product is the same but the bundles are different. Cheers !
