Optimal setup for Multi Domain WordPress with Woocommerce

So, as a word of warning, WooCommerce doesn’t officially support multisites that draw from the same product database. Some (a lot) of extensions won’t work correctly, so just a heads up on that aspect.

It sounds like a good workaround would be to install the five sites separately, and have them all connect to the same database software. Square, for example, has database and inventory capabilities – if they all connected to the same Square account then they could draw from the same inventory.

The best solution would be to link it to an external database, and you could use the WooCommerce REST API to build out any connection to another service if it’s not available on the WooCommerce.com extension catalog.
