Services revenue definition

The Services Top 100 ranks IT services companies. Companies are ranked on the basis of relevant revenues in the last calendar year.

Relevant revenues include revenues from IT consultancy, system integration, hosting, IT outsourcing, custom software development, software customization & implementation and training services.

Excluded are revenues from software sales, hardware sales, communication services, software-as-a-service, business consultancy, accountancy, administrative services, and standardized software support & maintenance. Business process outsourcing revenues are excluded in case they have no relation to IT.

Sources
Data is gathered from SEC filings, annual reports and corporate websites. In some cases additional information is requested from investor relations departments, or obtained from market research agencies and internet media.

Comparability
To make company revenues comparable, calendar year revenues are used for the list. Corrections are made when financial years do not match calendar years. Corrections are also made to eliminate exchange rate differences: all revenues are presented in US dollars. The exchange rate at the end of the relevant calendar year is used in the calculation.

Uniformity
Although it is attempted to gather and present all data in a uniform way, differences in corporate accounting policies are likely to provide minor distortions in revenue recognition.

Reproducibility
All revenue calculations and data sources are available to the public so that the information in the list can be verified independently.

Integrity
The Services Top 100 is made by independent researchers from the Top 100 Research Foundation. Companies do not (can not) pay to be on the list. The only qualification for a position on the list is: sufficient IT services revenues.

Timing
A fresh edition of the Services Top 100 is published annually, after the IT industry has published the necessary annual reports. Typically, publication of the fresh edition takes place in the second half of July.
