Cost Per Signed Case Guide

Lead price alone does not tell you if a campaign works. Cost per signed case connects spend to intake outcome, consultation quality, and retained matters.

Formula

Spend divided by signed cases

Track each source separately so good and bad campaigns do not blend together.
