Yes, you can connect more than one Shopify store or Amazon stores for multiple regions (US/Canada/Mexico, pan-EU, etc) into one Inventory Planner account.
Note that adding more connections or stores to your Inventory Planner account will commingle vendors and purchase orders. If you want this information to show separately, you will need to set up a new Inventory Planner account.
To connect a second store, go to Account > Settings
> Connections & arehouses > Connect Another Platform.
If you want product, vendor, and purchase order information all showing in the same account, then select the option seen above to add the new connection to the existing account.
If you want all information separate, then click on:
'New Connection in a separate account'.
A notice will be shown to explain the effects of using this option.
If you are happy to proceed, use the option 'Create new separate account'
