To accurately sync Stock Adjustments from Unleashed to Xero, a Cost of Goods Sold (COGS) account from Xero must be allocated in Unleashed before the Stock Adjustment is completed. 

When a new Stock Adjustment is created in Unleashed the Xero integration's default COGS account will be automatically be allocated to the Stock Adjustment. 

NOTE: You can review your Xero integration's default COGS account by heading to Integration, Integration Store, click on the Xero tile and go to the Configuration tab. For more details, see Xero Integration Setup: Configuration.

However, if you'd like to specify an alternative COGS account for the Stock Adjustment to export to in Xero, use the Account dropdown menu in the Stock Adjustment to select the appropriate account. 

If a product has COGS account allocated in it's product record (not the default COGS), the Stock Adjustment's selected COGS account will take precedence. The product record's COGS account will only take precedence for Sales Shipments and Credits. 

NOTE: The COGS account selected in the Stock Adjustment cannot be amended once it has a Complete status.
