Do I need to create BQE CORE accounts for all employees entering time?

Not necessarily. You can set up your employee profile in the Employees screen and enter time on their behalf. However, this is not efficient. If you want your employees to enter their own time, you need to set up a BQE CORE account for each of them and assign them the Time & Expense security along with the right subscription that allows them to access the Time & Expense features. Check CORE Help Center for details on setting up employees and managing CORE users. Please check with your Sales Account Manager to purchase the required subscriptions.
