Hello there, Frenni Dan.

I do appreciate your time and effort in adding the Cash Flow menu in the left panel. It can be that you're using QuickBooks Online Accountant which does not support the Cash Flow tab at this time. If you're using the regular QuickBooks Online account, I'd suggest reaching out ot our Phone Support Team so they can further check the root cause of this issue. 

Here's how: 

1. Go to the Help menu.
2. Enter talk to a human.
3. Select Live chat. Then, click the LIve Chat link.

Feel free to use these articles that will help you manage your Cash Flow: 

• Get started with the Cash Flow menu
• Use the Cash Flow planner to predict future income and expenses

I'm just around if there's anything else that you need help with. Take care and have a great day!
