Once loaded an invoice, how do you view it from the main menu?

You can view your loaded invoice on various pages in QuickBooks, @karl-deans-shine. I'd be delighted to guide you and go over the specific steps required to complete your task with you.

You can examine the loaded invoices on the Invoices page, Customer Transaction List, or Report. 

Here's how: 

1. Go to the Sales menu on the left side. 
2. Select the Invoices or Customer tab one at a time. 
3. Click the customer name and review the transactions. 
4. Filter the Status and Date to see the specific data. 
5. Hit the small gear icon on the upper right corner to add columns. 

To pull up a report, complete these steps:

1. Go to the Reports menu. 
2. In the Sales and Customers section, you can run the Transaction List by Customer, Invoice List report, and more. Click here to know the different reports available in your account. 
3. Select the Customise button and filter the appropriate data.
