Increase price by $1 or revenue by $1
If you have a hardware and a software/internet business: would you rather increase price by $1 or revenue by $1 for each business. My logic is that for a software or internet business, adding an additional customer would not be associated w/ much variable cost, as the software or internet business already has fixed costs like hosting set up. Thus an increase in revenue would mainly flow to income statement. For a hardware business, producing an additional unit requires significant variable cost (materials, manufacturing, etc).
I could have it the other way around, though.
