Hi, @Gdottore.

It's good to know that you're following the steps given by my colleague. No worries, I can walk you through few steps to fully resolve it.

There are only two reasons why transactions are showing in the Unapplied Cash Payment Income account. It's either you record the payment before creating the sales form, or they weren't matched at all.

You can start with running the Open Invoices report to verify transactions showing as not yet paid. Here's how:

1. Go to Reports, then enter Open Invoices in the Find report by name section.
2. Set the report period, and click Run report.

If the Payment transaction matched the open invoice, you can proceed to Step 2. If it doesn't, go directly to Step 3.

Step 2

1. Select the Payment date to open and click on Receive payment.
2. Under Outstanding Transactions, check the open invoice.
3. Select Save and Close.

Step 3

1. Select +New and go to Invoice under Customers.
2. Enter the customer, amount and date as the payment.
3. Save and Close.
4. Go back to the Open Invoices report.
5. Find the unapplied payment and click the date to open.
6. Under Outstanding Transactions, check the open invoice.
7. Select Save and Close.

Repeat the same steps until there are no payment transactions anymore.

Run your Profit and Loss report again. You should no longer see the Unapplied cash payment income anymore.
