Small businesses on the other hand will normally try out a demo of the product and decide on the spot if they like it or not. They aren't all that way, but if you talk to 50 10-person businesses, at least a couple of them will probably be willing to buy on the spot if your product solves a problem for them at a reasonable price.
Go get some of those tiny customers even if they're not profitable for you, and then later move upmarket to the enterprise clients you really want. Or do what I do and just stay focused on small customers indefinitely because they're so much better to work with.
