Hi there,
I'm so glad to hear that you've signed up for QuickBooks Online to help with your business bookkeeping! I know how important it is for you to access all of your tools and resources within the account. Great job trying some preliminary troubleshooting. I'll help you get this sorted out.
When you say toolbar, I figure that you're referring to QBO's left navigation menu, as this is the only bar of tools in the account. If you're not seeing the options down the left-hand side of your account, use the three horizontal lines at the top of the page to collapse and expand this menu.
If you don't see the three "sandwich" lines used to expand and collapse the menu bar, take a look at this helpful article in which my colleague explains how to restore that option: Expand and Collapse Left Navigation Menu.
I know you've already tried clearing the cache and cookies in your browser, however if the above steps don't resolve this issue, try using a different browser all together.
I hope this helps get you back on track. If you're still not seeing the 'toolbar' you're referring to, please reach out to our tech support team so an agent can take a closer look.
Have a great day.
