Nothing gets software vendors more excited than new government regulations. Sarbanes-Oxley was a boon to enterprise software companies a few years ago. It allowed them to walk down the hall from the CIO's office and talk to the chief financial officer, the person who controls the company's purse strings. Similarly, TMS vendors welcomed the new Hours of Service regulations when they first went into effect in 2003. It was part of the "perfect storm" shippers and carriers were facing at the time (along with rising fuel costs and capacity constraints) that served as a catalyst for TMS sales. The latest regulation that has vendors seeing dollar signs is the Importer Security Filing (ISF) rule, better known to folks in the industry as "10+2."
