Shopify provides all the technology they would need to run an online store. That means two things. It means the front end of the store, so the storefront that you would go and visit—if you go to LaBottega.ca, the thing that you see—but also the back end where they do their inventory management, fulfill orders, and have the ability to accept payments. It's effectively a business in a box.
