I have an insurance agency and a carrier I represent wants to advance me a loan for 6 months. How do I record it?

I appreciate your time posting here, Martin.

I'll be glad to share the steps. If you want to track the loan and get reminders of the upcoming payments, you can read this article for the detailed steps: QuickBooks Loan Manager. Otherwise, set up the accounts for your loans and manually track them. 

To add a liability account, you can follow these steps:

1. Go to Lists > Chart of Accounts.
2. Click the Account drop-down menu, and select New.
3. Select Other Account Types, and choose Other Current Liability: Use this for short-term loans payable over one year or Other Current Liability: Use this for short-term loans payable over one year.
4. Click Continue and enter the account details.
5. Hit Save & Close.

Please see these sample screenshots for a visual guide: 

If you already added carrier I as a vendor, you can proceed with adding the expense account.

Here's how:

1. In the Chart of Accounts page, click the Account drop-down and select New.
2. Choose Expense and click Continue.

4. Hit Save & Close.

Once done, you can record the loan by following these steps:

1. Go to Banking > Make Deposits.
2. Select Cancel if you get the Payments to Deposit window. 
3. In the Make Deposits window, select the account to deposit the loan into from the Deposit To field.
4. Choose the Date and enter an optional Memo.
5. In the From Account column, select the liability account you created. Then, enter the loan amount.
6. Hit Save & Close.

When it's time to record the loan payment, you can follow these steps:

1. Click Banking > Write Checks.
2. From the Bank Account drop-down list, select the account you want to use to pay the loan. Make sure to verify the Check NO. and Date.
3. From the Pay to the Order of drop-down menu, select vendor's name.
