I appreciate you sharing additional information. I truly understand how valuable your time and efforts are. I'm here to help record these transactions. Consider me your partner in this, @blueview1901.

In your case, we can create a bank deposit with the total amount of each invoice and split it when we use the Receive Payment feature. Make sure to select the Accounts Receivable as the account.

Here is the step-by-step guide: 

1. Click +New. Select Bank Deposit.
2. Head to the Add funds to this deposit section. Pick your preferred customer.
3. Choose Accounts Receivable in the Account dropdown.
4. Enter the amount. Once done, hit Save and close.

Please see the attached screenshot for a visual guide.

Now, let's open one associated invoice.

1. Hover to the Sales menu. Locate only one invoice included.
2. Press Receive payment.
3. In the Outstanding Transactions area, tick all the entries needed.
4. Save and close.

For future reference, you can set up automatic invoice reminders, which saves you the hassle of manually tracking due dates. Check out this article on how to set this up: Send invoice reminders automatically.

I appreciate all the efforts you've already put in. I'm here to assist you every step of the way, so tell me how it goes after following the steps above. I hope everything goes well, @blueview1901!
