The Days Open Metric calculates the average amount of days that lapse from the date an Order is created to the date it is either Confirmed or Cancelled.
The averages are calculated over the past 6 months.
Proposals display the average number of days open from creation date to today's date for all current Proposals.
Use the Days Open Metric to gauge how effective your sales process is.
Also check out the Days Open Report for a more detailed breakdown of the Orders that make up the average calculations.
