Software: Intuit QuickBooks Online, Singapore
QuickBooks Online does not permanently “lock” up the transactions, it allows the authorized user to amend the transaction when a genuine mistake was made.
To prevent unauthorized modification, QuickBooks Online has a “Closing the Books” protection feature, which administrator can set a closing date and a password, to prevent unauthorized user from saving a transaction which was dated before the closing date.
You can find the “Closing the Books” feature under the sub-menu of the Company Preferences.
To prevent financial fraud, QuickBooks Online has a built in Audit Log, which tracks all the changes made in the transaction. Besides the new and edited transactions, QuickBooks Online does provide a log file which shows the user logged in and out from the system.
