How do I match a downloaded transaction that is a partial payment to a bill already posted in QB with the full amount?

Welcome to the Community, @zjbadra. 

QuickBooks can only detect a match when the transaction's date and amount entered are equal to what's on your downloaded bank transactions.

To make sure the paid bill will match with the partial payment posted in the bank feeds, modify the amount you've entered in the Bill Payment page, then manually search a match in the for Review tab. Here's how: 

1. Go to the Expenses menu, then select Vendors. 
2. Select the vendor's name, then locate the Bill Payment transaction. 
3. Click the View/Edit link under the Action column. 
4. Modify the amount paid in the Amount field. Ensure to enter the same amount showed in the bank feeds. 
5. Click Save and close. 

Once done, follow the steps to find the match in the Banking page. Here's how: 

1. Locate the transaction in the For Review section. 
2. Click the transaction to expand the view, then select the Find match button. 
3. Mark the box check for the transaction to match, then click Save.

Hi

The info does not match my screen. I can find the supplier. You call it vendor. After that there is no tabs you mentioned. I am on Quick books online. 

Thanks for joining the thread, @pinkpetunia.

I can help you further by providing screenshots to find out the vendor's name in QuickBooks Online (QBO).

Here's how:

1. Go to the Expenses menu, then select Vendors. 
2. Click the vendor's name, then locate the Bill Payment transaction.
   
   
3. Select View/Edit View/Edit under the Action column.
   
   
4. Change the amount paid in the Amount field and then make sure to enter the same amount showed in the bank feeds.
   
   
5. Click Save and close.

Once done, you can follow the steps given by my peer on how to find the match on the Banking page. You can also check out this link: Match online banking transactions.
