How to record security deposit from customer

We are a rental company, and we take security deposits from customers in advance and we return back to them after 1 month of the leasing period. In Quickbooks, we do

1.issue an invoice with the item name "security deposit" as a current liabilities

2.as we refund back the money to customer, we use credit memo to refund the money back

In zoho books, we cannot issue invoice with items as "current liabilities" , so how could I record the above transactions?

thanks
