Your confusion ends here, @pinku-estarbizad.
Allow me to fill you in on everything you need to know about inviting employees to access timesheets.
Currently, you'll have to use QuickBooks Time to invite your employees to let them access their specific timesheets. As a workaround, you can look for a third-party app you can integrate with QuickBooks Online to have this option. To find a third-party application, you can go to the Apps menu and search for an app that can set employees to see their specific timesheet.
In addition, you might want to utilize the time tracking feature in QuickBooks Online. This allows you to add your employees as time tracking users and enter their hours.
Please know that I'm just a reply away if you need any further assistance adding your employees to enter their timesheets. I'm still open to your replies, @pinku-estarbizad.
