Hi - How do you match a bill AND an invoice on the transactions - the bill is higher than the invoice and so is only showing bills to match - I'm quite new to QB! Thanks

Thanks for sharing the details here, @accounts-progres,

When you match transactions in QuickBooks, both entries must be the same. In your case, it looks like you are trying to match an expense (outgoing funds) to your income(incoming funds). Since this is not allowed, you will need to do the match separately.

If you have a credit card payment in your bank statement, create an expense in QuickBooks to match it. For further information on how to do this, see this article: Record your payments to credit cards

The next thing you need to do is match the customer payment from the bank to the recorded payment in QuickBooks.                                                                                                                                                                                                                                   

Since the refund is greater than sales, this will require a few steps to do. But don't worry, I'll be right here to guide you through that.

Step 1: Create the sales transaction and receive the payment to the Undeposited Funds account.

1. Go to the + New icon and select Invoice or Sales Receipt.
2. Enter the details of the sale then hit Save.
3. On the same transaction, click Receive Payment. You can also close the invoice or sales receipt and go back the the + New icon and select Receive payment.
4. Pick the invoice to pay and ensure the Deposit to field is showing Undeposited Funds. See this sample screenshot:
   
5. Hit Save and new.

Step 2: Create the Refund Receipt showing the original refund amount of $250.

1. From the + New button select Refund Receipt.
2. Enter all the information with the correct date.
3. The Refund From field has to have Undeposited Funds too.
4. Lastly, click Save and new.
   

Step 3: Create a Journal Entry to move the funds from Undeposited Funds account to Bank account.

1. Go back to the + New button at the top, then choose Journal Entry.
2. Set the date of the transaction that is same as bank posted transaction date.
3. On the first distribution line of the Journal Entry, select the Bank Account.
4. Enter the total amount that you received from the bank in the Credits column. The amount is the difference of the sale and the refund.
5. On the second distribution line, choose Undeposited Funds.
6. Set the Debits column to the same amount as the Credits column.
7. Click Save and close. This will show a deduction from the bank account in the Bank Register in QBO.
   

Step 4: Group the Journal Entry with the payment and refund to create a $0 deposit.

1. Click the + New icon then Bank Deposit.
2. Select the payments (negative and positive) and the Journal
3. The entry you just created (the total should be zero).
4. Click Save and close.
   
    

Once done, go back to Banking page. You should be able to see Match option this time. If not, click that transaction row for refund receipt to find a match.
