One of the beauties of B2B is that there is a finite number of customers. So the marketing costs are much lower. Do you agree?

Business that sells products or provides services to other businesses.   As the product one business is the need for the other business, the demand keeps on going the same way supply also.  There is high degree of certainty of business and one can easily forecast the present and future business.  The potential for business also can be worked out by have a close watch and contact and once a smooth relationship is established and a channel is well created....that is its beauty. And so the marketing costs also get reduced and may even tend to a nill stage.

In B2B both are scoring on the same goal post.

AGREED AGAIN WITH KRISHNA,,, HE IS MASTER BLASTER OF MARKETING,,, APPRECIATED
