Products and Sales process

Hello.

I am new to zoho crm and I have a few questions.

I work for a company which is renting costumes.

For example, I am sending one costume one day and I recieve it back 3 days later. This means that if I have in my stock 10 costumes after sending 4 of them I will have 6 costumes in my stock and after I recieve them back I will have 10 again. What I'm saying is that my quantity in stock is self-renewable every time I have a return. Is there a solution for this both for the sales order and the quantity in stock?

Another problem I experienced while using zoho crm is in the product customization. Our product (costumes) is consisting from some subitems and the quatity is the minimum of the individuals quantities of the subitems. For example,

product A = subitem 1 + subitem 2 + subitem 3
quantity in stock of product A = min (qty in stock of subitem 1 , qty in stock of subitem 2 , qty in stock of subitem 3)

Is there a solution for this?
