Hello, gorhamenterprise1.

I'm here to help you perform a double-entry transaction in QuickBooks Desktop. I'll also add more details regarding the processes. 

Just like what Rustler said, entering transactions in QuickBooks Desktop already involves double-entry accounting. What particular entry do you need help with? I'd appreciate more details about this.

You can create a sales receipt, an invoice, or a supplier's bill through the tool bar menus at the top. Using the shortcut icons is also a good way to create a double-entry accounting transaction. 

You can check the articles in these topics if you need help entering them: 

• Manage Suppliers and Expenses
• Manage Customers and Income

If you'd like to know the breakdown of the recorded transactions, you can run the Journal report. It shows you the debit and credit of every transaction and what accounts are affected. Here's how to run it:

1. Go to the Reports menu.
2. Hover your mouse on Accountant & Taxes.
3. Choose Journal. 

You can find more articles here in case you need help with other tasks in QuickBooks Desktop. 

If you need help recording a specific transaction, please let me know. I'll be here to help. I also welcome any QuickBooks Desktop concerns you might have.
