In a Property Management System (PMS), a security deposit is a sum of money collected from a guest at the time of booking. Its main purpose is to protect the property owner or manager against potential damages, unpaid fees, or violations of rental terms.
In AdvanceCM, you can find the Security Deposit module under the Finance menu option.

Security Deposit Type
You can create Security Deposits using two different methods:
Automatic
Manual
1. Automatic Security Deposit
You can find the automatic security deposit option in Rental Settings at the rental level. If a security deposit is set at the rental level, then whenever a Security Deposit Automation rule is triggered, the deposit will be created based on the amount defined on the Rentals → Automatic Security Deposit tab.
Amount: Specifies the amount for which the security deposit will be created and charged to the guest.
Type: Indicates whether the Amount is a flat value or a percentage of the booking total.
Modality: Defines how the security deposit is applied to the booking.

2. Manually Adding a Security Deposit
You can manually add a security deposit using the Security Deposit List View.
