The Swantide Workflow, titled "Calculate the # of Days Between Opportunity Closed Date and Created Date," provides the duration an Opportunity took from its creation to its closure.
It automatically computes the number of days that lapsed between the creation of the Opportunity and the date it was closed.
This calculation is triggered only once the Opportunity has been marked as closed, ensuring that the results represent the full duration of the Opportunity's lifecycle. This workflow is essential for businesses seeking insights into the time efficiency of their sales processes.
If you're looking for a Workflow to also consider the number of days an Opportunity is still open and the time it took till close then I recommend this workflow.
