Overpaying a credit card bill

I get how important accurate bookkeeping is for you, and I completely understand why seeing that balance pop up again was frustrating. To fix this, you just need to change the bill back to its original amount and then reapply the full $400 payment. This tells the system to properly track the remaining $300+ as a vendor credit.

The balance is still showing in Pay Bills because of how the bill was modified. By changing the original bill amount to $400, QuickBooks now assumes you formally owed that full amount. Since your actual statement was under $100, the system sees the remaining $300+ as an unpaid, past-due balance instead of a credit.

Here’s how to fix it:
 

1. Go to the top menu and select Vendors, then Vendor Center.
2. Select your credit card vendor from the list on the left.
3. In the Transactions tab, find the bill you changed to $400 and double-click to open it.
4. Change the Amount Due back to the original statement balance (the amount under $100).
5. Click Save & Close.

Since the bill is now smaller, we need to let QuickBooks know that your $400 payment covered this bill plus an extra prepayment. Here’s how:
 

1. Go to the Vendors menu and select Pay Bills.
2. Check the box next to the credit card bill you just corrected.
3. Look at the Amt. To Pay column at the bottom. Click into that box for the credit card bill and manually type 400.00.
4. Click Pay Selected Bills.
5. A warning will pop up saying: "The payment amount is greater than the total of the selected bills. QuickBooks will create a credit for the remaining balance."
6. Click OK or Save to accept it.
