Lumopath · Cost to Serve

Know what each customer really costs to serve.

Cost to Serve reveals the all-in cost of every client and segment — across every team, not just support tickets — so you can see your margin leaders, your time sinks, and exactly which levers move margin.

The problem

Same revenue. Four times the work.

Revenue tells you what a segment is worth. It says nothing about what it costs. SMB pulls in about the same revenue as Midmarket — while consuming roughly four times the hours. On a revenue dashboard, you'd never see it.

At equal revenue ~$5M each
Midmarket≈ 2.3K hrs
SMB≈ 8.7K hrs
Revenue says they're equal. Cost says they're not.
