Hi,

To close a financial year, use the menu Accounting‣ Periodical Processing ‣ End of Period ‣ Close a Fiscal Year. A wizard opens asking you for the financial year to close.

In order to close a fiscalyear, you must first post related journal entries.

When the year is closed, you can no longer create or modify any transactions in that year. So you should always make a backup of the database before closing the fiscal year.
