At the maintenance screen of your accounts receivable via [Finance, Accounts receivable, Maintain], at tab ‘Financial’, you can select an offset account. You have the possibility to select a revenue account that will be used to book revenue when printing a final invoice. At the maintenance screen of an item via [Invoice, Items, Maintain], at tab ‘Financial’, it is also possible to select a revenue account.
You can determine yourself whether the revenue account that is selected at the item or at the account receivable is used when printing the final invoice. Via [System, General, Settings, Invoice settings], with the setting ‘Revenue account’, you can choose which revenue account should be used.
