Personally...
I use aroma for the odor of food, perfume only for the liquid scents in bottles, fragrance for the smell of "girly" things like foam bath, pot pourri, candles... and scent (one you didn't mention) for any other pleasant smell as in soap, detergents (laundry, dish, household).

For business...
Perfume is the official term we use in the ingredient listings of products.
