This version of the IT Services B2B Databook  includes: all 129 countries, 24 2-digit NAICS code industries, and 3 business size segments. The MS Excel workbook contains detailed estimates of market size for all combinations of countries, industries, and business sizes. Summaries and details support your marketing, sales, corporate planning, investor relations, and other functions.
 
Since data loses its reliability over time, we update the underlying data and estimates every six (6) months. Semiannual editions of the products expire 18 months after they are initially published. In lieu of a subscription, B2B Market Calc recommends that you purchase a new edition approximately 12 months after your initial purchase.
