where should the other leg of payments allocated to an invoice appear? I do not see that in the chart of accounts

You can use the Transaction Journal to view the invoices of what accounts are affected by a payment transaction in QuickBooks Online (QBO), dalener2019-outl.

To start with, if a payment is deposited into an Undeposited Funds account, the Accounts Receivable (AR) and Undeposited Funds (UF) accounts are affected in the following way:

• The AR account is credited, which reduces the outstanding balance of the invoice, showing that less money is now owed.
• The UF account is debited, meaning the amount of payment received temporarily increases the balance in this account until it is moved to a bank account.

However, if a payment is deposited directly into a Bank account:

• The Accounts Receivable (AR) account is credited, which reduces the outstanding invoice amount, indicating less money is owed.
• The Bank account is debited with the same payment amount, increasing the balance in the bank to reflect the received payment.

Here's how to view the invoices in Transaction Journal:

1. Log in to your QuickBooks account.
2. Go to the Sales menu and select Customers.
   
3. Choose the payment transaction and click View/edit.
   
   
4. In the Deposit to, select the correct accounts and click More.
   
   
5. Choose Transaction Journal.
6. Filter the Report period to show all the invoices.
