Commercial size of spending wallet (“CSoSW”) is the total business spend of a business including cash but excluding bartered items. Commercial share of wallet (“CSoW”) is the portion of the spending wallet that is captured by a particular financial company. A modeling approach utilizes various data sources to provide outputs that describe a company's spend capacity. Online marketplaces that allow small businesses to advertise their services can use this CSoW/CSoSW modeling approach to provide a rating that gives an indication of the business prospects of the vendors listed on their sites. Further, such marketplaces can combine this information with their own internal analytics to provide a single holistic rating.
