A manual store in ShipStation is a good option if you plan to upload orders via a CSV file or you occasionally need to add orders that do not import from a connected store.
By default, ShipStation provides one Manual Store so you can immediately create orders, even if you are not quite ready to connect a selling channel.
Add as many Manual Stores as you need to help organize your orders in whichever way works best for you.
Once connected, set your manual store settings for branding, notifications, and other options just as you would for any connected store.
Remember to save your changes!
