I'm using Quickbooks Plus. in my subscription,how do I enable "Cash Flow" option in the main menu.

Hi there, finance113.

To enable the Cash Flow option on the main menu, I suggest going to the QuickBooks Labs page. This way, the Cash Flow feature will show on the Dashboard. This widget provides a real-time view of your current cash balance along with a historical comparison of money in and out across all your connected bank accounts.

Here's how:

1. Click the Gear icon at the upper right corner.
2. Select QuickBooks Labs.
3. Click Cash Flow Dashboard Widget, then turn it ON.
4. Hit Done.

Once you refresh the page, the widget will appear as a card on your Dashboard along with all the other modules. To know more about how QuickBooks calculates your cash flow, you can click this link here.

You can also run a Statement of Cash Flows report to know how your business is doing by showing you the amount of cash that flows into your business, and the amount that flows out within a specific period. 

Follow these steps:

1. Select Reports from the left menu.
2. Go the search field, Type Statement of Cash Flows.
3. Select Customize button to change any of the settings for the report, if necessary.
4. Select Run report.
