Hello, @andrea37.
Let’s make sure that you’ve recorded your vendor payments as Bill Payment check, Expense or Checks.
Here’s how:
1. On the left navigation panel, choose Reports.
2. Use the search tab inside reports then type in Transaction List by Vendor.
3. Click to view the transaction.If the transaction is not yet paid, then you’ll have to enter bill payments. If it’s already paid, make sure to edit the date of the vendor payments.
You can refer to this article for more detailed steps: Enter, edit, or delete expenses in QuickBooks Online.
Also, let me add this article for future reference: Void or delete transactions in QuickBooks Online.
Thank you for dropping by, have a great day!
