It's important to keep track of lost reasons. We've set default reasons but everyone's business is different so you're bound to have custom ones.

Good thing you can add/delete and edit lost reasons in Salesflare.

Just go to Settings > Customize fields.

Click on the Opportunities tab at the top. 

If you have multiple pipelines, you can select which pipeline you want to edit a lost reason for in the top right corner.

Scroll down to Lost reason* and press the pencil sign to edit.

Here is where you can add, delete or edit your reasons. Just press Save and you're done.
