Step 1 – Check Lead Age

On odoo admin panel, Navigate to CRM > Pipelines 

Lead Pipeline will be like the below image in your CRM. You can see the stages like New, Qualified, Proposition and Won. These are user dependent and might have different stage names.

Click on the lead and go to the form view of any lead. You will see a tab – ‘Lead Age Audit’. The tab tracks each leads day at a particular stage. When you are using prospects, then in this case when the prospect is converted to lead’s new stage, the age will be calculated on the basis of when the prospect was created and when the lead has been converted. 

Step 2 – Check Lead Lifetime Report 

On odoo admin panel, Navigate to CRM> Reporting >Lead Lifetime 

You will see below report view with three different views – Pivot, Graph, List in reporting. The default is pivot view.
