Managing a Cold Storage Business

How do I manage a cold Storage Business, where I recive goods from my customers, store them for a period, maitaning templeature logs etc. And charge my customers the rent for the period for the stored items from those customers in erpnext.

The question is too broad with too little information or context.

How are you handling it now?
Do only charge “rent” based square area?
Do you charge for handling, moves, etc?
Are there any special charges?
Do you provide insurance based on value of merchandise?

What are unique costs to specific transactions that you’d like to track?
