If you've ever been asked "why do you need another CSM?"…

…you know the problem. CS leaders are expected to scale coverage and prove ROI with fewer resources — but the staffing case usually lives in a messy spreadsheet nobody trusts.

Headcount asks get denied

Without a defensible model, "we're stretched" sounds like an opinion, not a business case.

Books are unbalanced

Some CSMs carry 200 accounts, others 30. You feel it, but you can't show it quickly.

Segmentation is fuzzy

You suspect SMB is eating capacity that high-ARR accounts need — but proving it takes hours.

One tool. The whole staffing case.

Enter your segments, account counts, and touch model. The planner does the rest and gives you a clear read-out you can drop into a deck.

  • CSMs required — total and by segment
  • Your coverage gap vs. current headcount
  • Blended and per-segment book size (accounts/CSM)
  • Cost-to-serve as a % of managed ARR
  • A plain-English read-out + one-click Save as PDF
  • Runs in your browser. Nothing uploaded. Works offline.
