The mapping between apaleo and xero accounts can be configured in the menu "Account mapping config". The mapping is made through apaleo's property. The sales tax accounts with account type Vat or VatOnLiabilities are not displayed in the list. Not the main accounts (e.g. Revenue) but the sub-accounts (e.g. Revenue Accommodation or Revenue Accommodation (X%), ...) should be configured.

In the column "Xero account name" you can choose an appropriate xero account from the list. All xero accounts except the system accounts are in the list. You cannot map system accounts of xero, because you cannot send a booking on a system account in the manual journal. (See the start page for explanation, how the bookings are sent.)
