Commerce order will have 0 price when being placed, Once the order is placed all the users of specific role will get notification(this is working) and should be able to reply to that order(I am making a custom module and view for this) with their own price for that order. There will be multiple fields data to reply like price, qty, destination, etc.
I don't want to create a new order or order revision.I want to be able to somehow add all quotation data to that order for each user.I have seen some quotation like modules but they do not do what I need.
My question is where to save all those fields and data?How to relate it with that order?
How do I achieve that?
