You can choose to post Purchase orders to Xero. When populating the fields for Cost of Sales and Inventory we will be able to post purchase orders and supplier invoices to Xero. You will be able to choose your cost of sale account from the drop-down menu, however, you will need to create a new TallOrder control account for Inventory. We suggest naming it TallOrder inventory control. 

If you would like to post your cost of sale expenses via a journal from Inventory to cost of sale as items are being sold you will need to click the button inventory through Xero and set up your Inventory movement account.
