How to set different item selling prices for Zoho Commerce and Zoho Books

Item selling prices for Zoho Commerce and Zoho Books are in sync. If we update the Item selling price in Books, the same will happen in commerce and vice versa. I need a separate commerce selling price for online users and a separate books selling price for offline users.  I have a Zoho Commerce paid licence and a books free version(Price list option is not available for the free version ).
