Multi-Site Shopping Cart

Multi-brand commerce usually means separate storefronts with separate carts and separate checkouts. Customers shopping across brands are forced to manage multiple sessions, re-enter information, and track separate orders. That breaks the buying experience when the catalog spans multiple independently operated websites.

Three storefronts run as separate websites, each with its own domain, catalog, and branding, but the cart follows the customer between them. A cart merge engine consolidates duplicate products across sites and preserves brand attribution on every line item. Customers see a unified cart with items from every site they've visited, and shop by product rather than by website.
