Hi, had an invoice for $800 that was paid in cash. $30 of that cash was used to buy stationery and $770 deposited to bank. How do I clear the $770 deposit; only $800 show

I can help you with recording the invoice payment, @LRC1977.

You can record the payment you've received to your Undeposited Funds account. Then, when you record the bank deposit, add the cash you've used to buy stationary from the Add funds to this deposit as a negative amount. 

Here's how to add the invoice payment to the Undeposited Funds:

1. Go to the + New button and find Receive payment.
2. Select the customer from the Customer dropdown and the checkbox for the invoice you’re receiving payments for.
3. From the Deposit to dropdown, locate and click Undeposited Funds.
4. Provide all the necessary information.
5. Click on Save and send, Save and new, or Save and close once you're done.

To add the expense that you've made: 

1. Go back to the + New and select Bank Deposit.
2. From the Account dropdown, choose the account you want to put the money into.
3. Select the checkbox for the invoice.
4. Scroll down to the Add funds to this deposit section.
5. Enter the fee as a line item.
6. Enter the amount fee as a negative number.
7. Select Save and close or Save and new.

Refer to the following articles for more information about putting the payments you've received into the Undeposited Funds account and adding them to your bank account as deposits:

From here, you can run the Customer Balance Summary report to check the remaining balance of your customers. Check the following article on how to run and customise it: Run reports in QuickBooks Online.
