Hi all, I have a list of incorrectly categorised unpaid invoices I know have been paid how can change those to paid?

Let's make sure you'll be able to mark those unpaid invoices as paid, userpeteranddudley.

Before we start, may I know why these invoices weren't marked as paid? To make sure you'll be able to identify those invoices that you are referring to, you can run the Transaction List by Customer report. To this, you can follow the steps provided below:

1. Go to the Reports tab.
2. Search for the report. 
3. Make sure to select the correct Report period.
4. Click Run report.
   
   

Once you've already identified them, you can re-categorise them. Here's how:

1. Go to the Banking page, select Banking.
2. Under the Categorized tab, locate the transaction then click Undo.
3. Go back to the For review tab and click the transaction.
4. Select the correct category of the transaction.
5. Click Split or Add.
   
   

After you've changed the category, you can now click receive payment to pay the invoice.

1. Click on the + New icon, select Receive payment.
2. Locate the Open invoice. Make sure to select the customer, payment date, method. 
3. Input the amount of the cash or check received.
4. Click Save and close.
   
   

That should do the trick. Moreover, after you've categorised transactions, you'll also have to review your accounts to make sure they match your bank and credit card statements. To do this, learn how to reconcile transactions in QuickBooks. For more details, refer to this article for your guide: Reconcile An Account In QuickBooks Online.
