For instructions on how to check a lead status click here.

For an -in-depth understanding, please refer to the example below. 

Janes (merchant) had previously created a lead for Brian Williams. In order to check the status of this lead she clicked on the Lead module, where the Lead Segment opened for her by default. She saw that Brian was her most recent lead, which placed his name at the very top of the leads list. Jane glanced over to the  Status column and saw that Brian's lead Status was listed as Enquiry

Similarly Jane chose to view Brian's lead status by clicking on the Business Flow segment, where she saw that Brian was listed under the Enquiry column as well.

She can check Brian's status by going to Core Setup > Lead > Business Flow.
