Of course, these capabilities come at a cost. Different payment processors offer different pricing models.
Some processors charge a percentage of the dollar value of the transaction.
Others charge a flat fee for every transaction, regardless of the dollar volume. Still others charge based on volume or the number of bills converted or presented. In most cases, the biller swallows the costs of online billing, just as in traditional billing operations. Although customers of the consumer-focused consolidator sites have shown a willingness to pay for online billing, they are not likely to pay more than it would cost to mail in their payments. In the B2B world, some customers may be willing to bear some of the costs of e-billing by paying for things like financial services, but the model is still untested.
