Managing several WooCommerce stores separately gets tedious fast — different logins, repeated updates, no central view. WordPress Multisite solves the management side of that problem by letting you run a network of stores from one WordPress installation, though it's worth understanding what it does and doesn't handle before committing to it.
Multisite centralizes infrastructure: shared core files, plugins, and themes across every store in the network, all controlled from one dashboard. What it does not do by default is sync inventory, orders, or customer accounts between stores — each one still operates independently on that front.
It's the right call when you're running several related stores under one brand — different regions, currencies, or languages — particularly once you're past 4-5 stores where separate management becomes a real time sink. It's the wrong call when stores need very different plugin sets, when one store gets far more traffic than the rest (all sites share a single database, so performance issues can spread), or when you only have two or three stores, where the added complexity of network administration rarely pays off.
Setup follows a predictable path: back up everything and use staging first, enable Multisite via a wp-config.php change and the Network Setup tool, network-activate WooCommerce, then configure payments, shipping, and taxes individually per store — none of that is shared automatically.
On pricing, a standard 2-4 store conversion typically runs $400-$800 for setup and configuration. Larger networks with domain mapping or custom inventory sync logic cost more, scaling with the number of stores and complexity of the syncing requirements.
