Can I connect a second store?

Yes, on Pro and Scale. Pro covers up to 5 stores and Scale covers up to 10 stores. Base covers one store. To add a store, stay signed in to nouz. Then install nouz from the Shopify App Store on the other store. It joins the same workspace, which is your nouz account for all your stores.

Each store gets its own product costs, logistics rules, payment fee rules and overhead. That is on purpose. A shipping rate card that suits one store rarely suits another. You can also start from the store menu, with Connect another store. That row also shows how many stores you have, like 2 of 5 connected.

You switch between stores in the store menu at the top of the sidebar, without logging out. Every page follows the store you pick. You can also select several stores that sell in the same currency. Then the Overview, the P&L and Inventory add them up. How that works is in seeing several stores added up.
