About QB Community

A warm welcome to the Community, Jadallah.

I appreciate the screenshot you've provided. To make the balance accurate, as an initial step, let's delete the Cheque Expense.

Let me walk you through the process:

1. Click the View/Edit link.
   
2. On the Cheque screen, click More at the bottom and choose Delete.
   
3. Hit Yes to confirm.
   

Once deleted, let's recreate the Cheque Expense and link the bill. See the steps below.

1. On the supplier's screen, click the drop-down arrow beside New transaction and choose Cheque.
   
2. From the Cheque screen, Add bill # 1109.
   
3. Enter the Amount (5,000).
4. Hit Save and close.
   
5. This will correct your supplier's balance.
