LightSpeed POS for WooCommerce is a bridging plugin between your online store and point-of-sale system for your physical store. Now, this is how inventory stays in sync across your online and offline stores: anytime a sale is made from your website or your storefront, it can update stock automatically in both systems. You will be able to import products and categories from Lightspeed into WooCommerce with the same plugin.
