Closing a filing period
After you have filed your accounts and tax return, open Filing periods, choose the period end date and press Close period. Books then:
- freezes the totals (income, expenses, profit),
- locks all entries up to that date so they cannot be changed or deleted,
- starts the next period with new entries.
Made a mistake? Press Undo to re-open the period. You can always create reports for closed periods.
