Yes, you can.
By default, SynCommerce pushed orders to ShippingEasy (which is our shipping service integration) when a merchant has his/her ShippingEasy account connected.
You can however change this so that all orders from connected channels get pushed to Shopify for fulfilment and processing.
To achieve this;
STEP 1. Simply to the settings page.
STEP 2. From the settings page, click to the preferences page.
STEP 3. Then navigate to the orders tab of the preferences.
STEP 4. This will take you to a page that will allow you to indicate where you want to send all your orders from connected channels. Turn it on for your Shopify store to send your orders there.
