I appreciate you coming back, knapiks. 

To clarify, in a Journal Entry (JE),  the credit side represents bank account where the bulk payment is.

To link the JE to the unpaid invoices, you'll want to utilize the Received payment feature. This allows you to accurately track your accounts receivable and ensure that your financial records reflect the payments received from your customers.

Here's how: 

1. Select + New.
2. Select Receive payment.
3. Choose a customer.
4. Under Outstanding Transactions, select the invoice.
5. Under Credits, select the journal entry to apply it as a credit.
6. Select Save and close.

Alternatively, to track the A/R, you can consider running the transaction journal report to ensure that each one is applied to the correct invoice. I'll lay down the steps to help you find them. 

To check multiple invoices, we can use the customized Journal report: 

1. Go to Reports.
2. In the search box, search for Journal, then click the result. 
3. Click the Customize button.
4. Check Transaction Type, then select Invoice.
5. Add other customization settings if needed.
6. Once done, click Run report. 

Nonetheless, it is advisable to consult with your accountant to determine the best course of action. They can guide how to handle the situation appropriately and ensure that your financial records remain accurate and compliant.
