Squarespace/Printful Domain Connection

We're rebuilding a Wordpress website on Squarespace. The store is connected to an existing Printful account through Woocommerce. The Squarespace site is in development on its built-in Squarespace domain. If we create a new store in Printful and connect it to Squarespace on this temporary domain, what happens when we connect the permanent domain to Squarespace to launch the new site? Are there settings for the Printful store that will need to be changed?

 

The existing Woocommerce store needs to stay online until the Squarespace website is ready to launch. I want to confirm that we can create a Squarespace-connected store with products synced to the temporary domain so that they client can review and approve everything, then connect the permanent domain to Squarespace when we're ready to launch without any issues with Printful. Thanks for any help.
