Once you have created a Lead and at a later stage there is a need to make certain changes you can simply edit the lead and make the necessary changes.

Go to the "Leads" Module from the Left-hand side menu option.

Once you open a particular lead the Lead-view dialogue box will appear. You will come across the same form which you filled during the lead creation part where you can edit the existing information.

After editing the information you need to click on the ‘Update’ button to see the changes you did in the Lead.
