There are two main types of report in FlexBooker:
Metric reports can be used to report on aggregate data between a date range. A chart will be plotted of the data, and also the values for each day within the date range you choose will be displayed in a table below the chart.
Export reports allow you to export data, again within a date range, to a spreadsheet.
These reports can be accessed from the "Reports" page in the top FlexBooker menu.
