You have  the option to send all products and line items to Xero creating products in Xero inventory. It is Xero that will create a new product if it doesn't exist already. Xero currently does not notify users if new products are created. As Burdi doesn't create a new product in Xero there is no way for us to notify you of this. We suggest contacting Xero regarding a notification feature as the more people who ask the more likely Xero are to develop features such as this.
