I would imagine, though, that companies that are "on their game" enough to become big are probably also the kind of company that will realize that they are now being burned on per-transaction costs rather than fixed overhead, and have the wherewithal to spend the week required to recorde their backend for a different API. Some companies won't get around to it quickly (after all: successful companies are busy), but that still seems like an awkward thing to rely on.

So, on that note, have you thought about setting up fees that scale better for larger companies? If you are doing two million dollars a year, PayPal's fees (for an example; PayPal is even a little more expensive than most processors, but are simply so far reaching it is hard to avoid them) will have dropped to 1.9% from 2.9%, saving $1666/month; at $10 million a year, this is enough for a reasonably high quality full-time employee.

It is likely we will add volume-based discounts in the future.
