Here you'll find the chart of accounts, bank accounts and cost centers. Accounts are organized in categories and both can be managed here.

Chart of accounts [more]
Here you manage the chart of accounts of your accounting system (Assets, Liabilities, Expenses, Revenues, Balance).

Bank accounts [more]
Here you can enter the bank accounts (IBAN/BIC) of your organization. They can be linked to accounts in the chart of accounts.

Cost centers [more]
Besides expense accounts you can review your costs under other aspects. With cost centers you can automate a part of your cost accounting, namely the allocation of book entry amounts or invoice item amounts to cost centers and profit centers. This is a PRO feature (not available in the free version).
