Yes, don't charge $40 if you are targeting large companies. For me as a project manager at Big Co, $40 and $400 is exactly the same, if I'm willing to pay one I'm willing to pay the other. What I care about is how friction free the process of paying you that money is.
Also I would rather pay one company $1000/month than 5 companies $100/month for the same service. To be crass about it, it isn't my money, but it is my time.
