Census Bureau Economic Surveys are a key source for official statistics companies can use:
The Census Bureau conducts more than fifty business surveys each year including monthly, quarterly and annual surveys for on going official measurement of the U.S. economy.
Every five years, the Economic Census measures all businesses and provides the most comprehensive data available, by industry and geography.
These surveys set the standard for U.S. economic statistics, and are fueled by the data provided by individual businesses.
