For you to record the loan in QuickBooks Online, please follow these steps:

2. Select Bank deposit, then choose an Account to which the loan is sent.
3. Under Add funds to this deposit, select the received from the section, then enter what type of account loan.

Once you have recorded the loan, you can use that transaction to pay the vendor through Pay Bills. 

Here's how:

1. Click the +New icon on the left panel.
2. Go to Pay Bills, and under Payment Account choose which payment account you recorded for the loan.
3. Select the Vendor you are going to pay, then click Save.
