If you have updated your Xero chart of accounts, tax rates or tracking categories, these won't automatically update in WorkGuru and will need to be re-synced.
To update WorkGuru's with the latest settings in Xero, open the Xero dashboard (Accounting -> Xero) and select Get Tax Rates, Get Chart of Accounts and Get Tracking Categories from Xero as required.
Once you have re-synced the updated Xero data, click Set Defaults (Accounting -> Settings) to open the Update Accounting Settings dashboard. From the settings page update any of the settings with the updated Xero data as required and click Save.
