A flash report is a report which provides upper management in a company with a quick snapshot of how the company is performing. The report is prepared by a staffer who gathers information about liquidity, profitability, and company efficiency and presents it in a short format which is designed to be read quickly to get a quick overview of how the company is doing. The preparation of a flash report generally takes half an hour to an hour and can be included in the job responsibilities of various employees, depending on the structure of the company.

The idea behind flash reports is that while companies prepare extensive periodic reports which provide information about their financial health, the gaps between these reports are too long. Staffers such as the chief executive officer want to see snapshots between these reports so that they can immediately identify exceptions and take corrective action before situations get worse. The flash report may be issued daily or weekly, depending on how the company is organized.

In the flash report, the person preparing the report provides information about the volume of sales, how many units the company is producing, and what the company's cashflow situation is like. This is done with the understanding that the numbers may not be entirely accurate, but that they can be used to provide generalized information about the health of the company. The person preparing the flash report usually works with a specific set of parameters so that the information between reports can be compared.

Often, flash reports are presented in a format which allows for quick comparison between other reports so that people can see changes. The report may be compared to the previously issued report, to a report issued in a different year at the same time, and so forth so that patterns can be noted and followed. If a flash report deviates from an expected pattern, it can be a sign that there is a problem which must be addressed.

Various people can be responsible for a flash report. Staff in accounting are often in charge because they have access to the financial information needed. A secretary or executive assistance may also be charged with preparation of the report. Flash reports which take longer than an hour to prepare are generally too detailed and extensive to be of use, as they go beyond a quick presentation of data. If a member of management wants to drill down a specific area of a flash report to get more information, he or she can request more data from the person who prepares the report.
