Every customer need Cashflow to track their In-Out bank operations.

By default Odoo Enterprise provides the report. But is it work correct?

I see it is not. Let me explain the main issues:

1. Cash Flow is hard coded without any reasons. 

• a user can't add any new lines
• a user can't drill-down to accounting move lines or other details
• a user can't check report's settings if he need to find the unexplained differences
• a user must understand how the report works with Tags/Account Types.

2. Out-of-the-box CF provides with the wrong results.

3. Cash Flow works as Cash flows from unclassified activities just a sum of account move lines without any Tags. This is a shame. Why do I can see Expenses/Incomes accounts in the Cash Flow? Does Odoo Master of Accounting know the difference CF and PL?

4. Accrual report not Cash Based.

With Odoo you have to reconcile all bank operations if you need Cash Flow. And this is a problem also. Invoices and Bills are not created at day of transaction.

Cash Based method is more clear for customers: you have just upload the bank statement and set accounts. Then Cash flow is ready.
