I purchased a truck from a dealer with a loan and using a trade-in for my business for $24,497. How do I make all appropriate entries in QB Desktop Pro to show sales tax, documentary fees, title and registry fees and cash down payment?

Let me help you record your purchased truck with a loan, @DrainageGuy.

Here's how:

1. Let's create a Fixed Asset Account for the truck, by going to the Accountant menu. 
2. Click Chart of Accounts and hit New. 
3. Select Fixed Assets. 
4. Enter the name and description for the account
5. Choose the Detail Type.

Once done, you'll need to record the purchase and link it to the Fixed Asset account.

Then, set up a liability account. Here's how:

1. Navigate to the Accountant tab and click Chart of Accounts.
2. Select New. Choose Long Term Liability and then Next. 
3. Enter the details and the name.
4. Click on Save.

Now, here are the steps to record the loan amount:

1. Select Accountant menu.
2. Tap Make General Journal Entries.
3. Click on the Account drop-down options and select Liability Account.
4. Enter the total amount for the loan on the Credit column.
5. Choose the Asset Account that you want the loan amount to be linked with.
6. Enter loan amount again but this time on the Debit column. 

Also, it's recommended to always create a backup copy of your company file before doing any changes. This is to ensure you have an original copy and restore it anytime. 

For the best advice on how you can record it, I recommend consulting your accountant. If you don't have one, no worries you can look for a Pro-Advisor near your area using our Find an Accountant tool.
