How to assign classes for payment received (from invoices). I want that the payments received to be shown according to classes in the statement of cashflow

I'm here to guide you through the steps on how to show the classes in the report, ojffinancekonsul.

The function to allocate classes to payments received is currently unavailable. Instead, you'll have to assign them to the invoices so they appear on the Statement of Cash Flows.

If you haven't turned on the feature yet, let's head to the Categories section to accomplish this task. Here's how:

1. In your company, go to the Gear icon and select Account and settings under Your Company. 
2. Tap the Advanced menu on the left panel and click the Pencil icon for Categories.
3. In the Track classes, move the slider to the right to activate it and check the box for Warn me when a transaction isn't assigned a class (optional).
4. Under Assign classes, choose One to each row in transaction or One to entire transaction.
5. Press Save and Done for the changes to take effect. 

This reference provides in-depth information about the process, including how the Assign classes function works: Turn on class tracking. 

Next, add your classes in QuickBooks Online (QBO) and assign them to transactions. Then, open the report and customize it to see the list of segments used on the sales entries.

Here's how:

1. Navigate to the Reports menu on the left panel and enter Statement of Cash Flows in the search bar.
2. Tap the Report period drop-down and set the correct date range.
3. Press the Display columns by drop-down and choose Classes.
4. If you wish to add more details about the report, click the Customize button.
5. Choose Run report to apply the changes.
