This term is used to keep track of the amount of items/products sold throughout the networking business industry. Usually used to keep track of the numbers the recruits are producing as well. Volume is sometimes referred to as the amount of shares each company currently has, however, that is only if the company has anything to do with stocks.
Volume equals success. The higher the volume, the higher level of success you have. It is essential that recruits keep their volume at the highest possible because that is the only way to increase the amount of commission you pull in. Also, this includes the amount of people they recruit to join the downline stream.
