There is no separate transaction type to enter and pay Loans in NetSuite. This is currently a system limitation and has been logged in Enhancement #80559.
But as an alternate solution, create a Deposit transaction to enter the loan amount and a Check transaction to record the payment.
Entering Deposit record
- Navigate to Transactions > Bank > Make Deposits
- On the ‘Other Deposits’ subtab, enter the Name (the bank/financial institution), Account (the Long-term liability account for the line of credit), and the Loan Amount.

We have created the entity ‘Bank Loan Test’ as a vendor record for testing purposes.
The GL Impact of the Deposit will be as shown in the screenshot below

Entering Check transaction
Create Checks to track loan payments on a monthly basis.
- Navigate to Transactions > Bank > Write Check
- Select the payee (the bank/financial institution where the credit is owed)
- On the Expense subtab, select the Account (the Long-term liability account for the line of credit), and the Loan payment amount.

The GL Impact of this transaction will be as in the screenshot below

Note: The check payment can be memorized to either remind you that there are checks to write or it will automatically post the check as a loan payment.
