You can set commissions for all items within an order. To do this head to the order where you want to set the commission and head to the "Commission" tab. Here you will see all items within the order. The "Sold by" field will automatically be populated by the user that added the item to the order. However, you can change this by selecting on the current user that has been selected, then all users and practitioners within your system will appear on the drop down menu. You can then select which user/ practitoner should get the commission for this item...
Once you select a user/ practitioner from the drop down list this is automatically saved.
You can then track commission using the Sold items report, please view the guide here for more info.
If an error message pops up when trying to change the commission of an item then please view the guide here as this will provide the details as to why.
