If you created your bexio account before June 24, 2015, your balance sheet and income statement are only structured to a limited degree. You can change this yourself, however.
Proceed as follows for the relevant account groups and accounts:
1. Create a new account group under "Settings - All settings - Master data - Chart of account groups for financial accounting":
2. Go to "Settings - All Settings - Master data - Chart of accounts for financial accounting". Now assign the accounts.
