Hi there, @AL KAMOKHA.

Currently, the option to create a vendor statement in QBO is unavailable. As a workaround, you can run the Transaction List by Vendor report and customise it. Here's how:

1. Go to the Reports menu.
2. From the search field, type Transaction List by Vendor.
3. Click the report to open.
4. Now to add a column for Paid and Unpaid, click Customise. 
5. From the Rows/Columns section, check the boxes for Open Balance and A/P Paid. 
6. You can also filter the transaction for a specific vendor.
7. Once done, click Run report.

For more info about the process, please see this article: Customise reports in QuickBooks Online.

Also, QBO offers a lot of vendor ready-made reports to track your expenses. To get started, simply go to the Reports menu and scroll down to the What you owe section. From there, click whichever vendor report you'd like to open

Feel free to post here again if you need further assistance in managing your vendor's info. I'll be around to help. Keep safe.
