Glad to have you connect with us in the QuickBooks Community. QuickBooks is a versatile program that enables you to syn other apps and extensions. I'll be happy to provide more info so you're well equipped with the knowledge to move forward.
In order to connect your Google Drive to your QuickBooks account, I encourage you to explore third-party apps our site www.apps.com. I suggest choosing an app that suits your business needs based on the app description. You can also send feedback about this feature to our engineers. To do this, click on the Gear icon and look for Feedback. New product ideas and improvements are largely based on the feedback we get from users like you.
In the meantime, feel free to ask other questions. I'm here to steer you in the right direction.
