I have allocated a payment to the wrong

Hi Wendy Cats, thanks for joining the Community :)

If the payment was allocated from the banking screen, you can undo this by navigating to the banking tab > categorised > locate payment in list > click undo. This will move the transaction back to the banking tab where it can be matched to the correct invoice. 

Hi Thank you i have just found the problem its a double payment 

a customer has paid for 2 invoices and made 2 £50.00 payment on the same day and time 

and QB has not shown one of the payments this has happened before is there a fix for this  

Thanks Wendy, if the bank is connected it is unusual that the transactions would not be downloaded to QuickBooks. Had both transactions completed processing through the online bank (no longer show as pending)? 

so both Payments of £50.00   was paid on the same day at more or less the same time 

they are both on my bank statement but only one came into QB  

It’s my goal to help you find the missing downloaded payment, Wendy Cats.

Let’s change the date set in the For review column to show all downloaded transactions from your bank. Thus the period entered in the Dates column affects how the data is displayed on the Banking screen.

You’ll be glad to know that it only takes a few clicks to perform the process. Here’s how:

1. Open your QuickBooks and navigate to the Banking menu on the left panel to choose the Banking option.
2. On the Banking screen, click the Blue tile icon and choose your Financial Institution (FI) from the list.
3. In the For review column, click the Dates drop-down and select the correct period or enter the date range in the From and To boxes.
4. Click Apply to reflect the changes.

After setting the date, look for the payment. If you continue to get the same result, perform Steps 1 up to 4 in the following article: What to do if you can’t find downloaded transactions in QuickBooks Online.

To keep your transactions organize, categorized and match them to the ones in QuickBooks Online (QBO).  For the double payment, these resources will guide you on how to efficiently handle the entry.

• Record a customer refund or supplier refund 
• Create and apply credit notes or delayed credits 

This troubleshooting should get you in the right direction today, Wendy Cats.
