Why it shows nothing (0.00 balance) in the balance section of vendor but shows balance in the paid section?

first guess is a journal entry or a payment to the vendor that had a bill but did not use pay bills

Thank you very much, Rustler for the reply. No, I haven't used quicbook pay bill for paying vendor.

I can clarify things out about the amount you're seeing on the Paid status for your expenses, ramkaji1999-gmai.

It shows the total amount you've paid within 30 days. You don't need to worry about it since you don't have open bills.

You can run the Bill and Applied Payments report. This will give you all the payments you’ve made and the bills that go with them. Here's how:

1. Go back to the Reports menu.
2. Scroll down to the What you owe section and look for Bill and Applied Payments.
3. You can also type in the name of the report in the Search bar to easily find it.

Let me also share these articles about running reports in the program for additional reference:
