hello
I have a rental Modul installed. Now I have the following problem:
If I for example. Product A to amount 50 euro. rent, I want the customer to provide a guarantee in the amount say 10% of amount 50 euro. This security payment is to be deposited as bail and are recognized upon return of the item in the financial statements statement.
My problem is that I do not know
how to implement this. Is there a module or knows someone there a solution as I first put a deposit in the account and then to charge the b bail after the conclusion of the rental amount with the total?
What would be the solution if the item is damaged comes back and I have to add any additional cost to calculate the deposit? Does anyone have experience and could help with?

Many many thanks
