With a Merchant Account in Extensiv Integration Management, orders from all order sources are merged when sent to ShipStation. The following setup is required if you have multiple sales channels flowing through Integration Management and need or want each to connect to ShipStation as a separate Store.

1. Use an Integration Management Fulfillment account. If you already have a Merchant account, contact support and they can upgrade your account for you.
   
2. Set up a unique Merchant in your Integration Management 3PL account for each sales channel.
   
3. Add the appropriate cart to each merchant in Integration Management.
   
   
4. Each Merchant in the Integration Management will have a unique sales channel connection to ShipStation. Follow the standard ShipStation setup guide using the Merchant Edit Setup page in Integration Management.

With this setup, each of your sales channels in Integration Management will be linked to a unique sales channel in ShipStation.
