'Website' will automatically appear as a sales channel. Any orders that are booked though your website will automatically be assigned to the website sales channel.
To create your other sales channels press Add sales channel > enter name > Create sales channel. It will then be added to your list of sales channels.
Examples of other possible sales channels could be Email, Phone, Face-to-face, Spaseekers etc.
To delete any sales channels press the three dots next to the sales channel you want to remove > Delete.
