Managing the financial period
The year is broken into periods. You normally have 12 periods in your financial year, each one corresponding to a calendar month. However MoneyWorks lets you have anywhere from two to fifteen periods.

A Financial Year normally has 12 financial periods and each period corresponds to a calendar month. During the setting up of the company file, you may consider having an additional period, the period 13, for audit adjustment. Unlike the Calendar Year, the Financial Year may not start from January as it depends on the financial policy of the company and the country's regulation, which your business has set up.
Assuming John has registered his business in April 2016, he will close his account by March 2017 if he wants to have 12 financial periods in his first year of business and yearly he will close his book as at 31 March. Now, if John prefers to close his account by December every year, then his financial year should start from January and ends in December.
MoneyWorks automatically open a new period for you if the administrator has given you the access right to "open new period". However, to Lock, Close, and Purge period has to be done manually as the software is not able to determine when the account has completed.
After you have completed the month-end or year-end account, you can temporarily lock the period to prevent unauthorised changes to the account by activating the "lock" period feature in the MoneyWorks accounting software.
The period, which is locked, has to unlock first before passing an audit adjustment. To prevent transactions accidentally posted into the previous financial year, you close the period after the audit adjustment has completed. You may consider backing up the file before closing the period since you cannot unlock a closed period.
Purging is optional. If you have a huge file of more than 3.5GB, you can consider purging the data. Although the transaction has purged, the account balance will be kept. After purging, use the "Save a Compacted Copy" feature to reduce the file size. You should backup the company file before purging since purging removes the transactions from the company file.
