Once you have created your sales channel you can now add these to orders. Any orders that are placed by customers on your shop front automatically have the sales channel 'Website'.
For any orders that are added manually and not through the website, you can go into the order and add a sales channel for them. To do this head to '+New order' or 'Orders' and select on an order.
Once you are on the order page, press on the 'Sales channel' option and a drop down menu will appear of all the sales channels you have setup. From here you can then select where this order came from.
Filtering orders by sales channels
Sales channels can also be used to filter orders so you will only see orders that were booked through the specific sales channel you selected.
To do this head to Orders > Filters > scroll to Sales channels > select which sales channel you want to filter by via the drop down menu.
This will generate a list of all orders that have been assigned this specific sales channel.
You can transfer the list that has been generated into a spreadsheet by pressing 'Export', this can then be saved or printed.
