Step 3: Red-Flag Cost Centers Early

Proactively identify high-risk cost areas — like cloud spend, vendors, or support-heavy teams—and monitor them for unexpected spikes. Set thresholds that trigger review before spend becomes a problem.

Why This Matters

At Series B scale, most cost explosions don’t happen overnight — they creep up silently until they’re embedded and painful to reverse. Early detection gives you time to fix without triggering layoffs or reorgs. This is how you protect margin without panic.

Key Activities

Identify cost centers prone to inflation:
Cloud infrastructure
Third-party vendors
Customer success headcount
Set QoQ growth thresholds (e.g., 15–20%) that trigger review
Build monthly reviews into finance-ops meetings
Analyze cost vs. value delivery: is it scaling with revenue?
Apply changes before costs calcify (renegotiate, streamline, reallocate)

Common Mistakes

Only noticing problems after Finance raises a flag
Waiting for year-end to review vendor spend
Treating all growth in spend as justified
Not having clear accountability for cost center owners
Ignoring “quiet” departments like DevOps or CS

Signals You're Doing It Right

You identify cost spikes before they hit cash flow
Department leads understand and monitor their budgets
Cloud and vendor costs are tracked relative to usage
You can explain what each large expense is doing for the business
Cost reviews lead to action—not just awareness

Red Flags

Large cost jumps are only noticed in retrospective reports
Vendor renewals happen automatically without scrutiny
Spend grows faster than revenue in specific teams
Finance and ops debate whether a cost is “worth it” with no data
Your margin is declining and no one knows why

Who Should Own This
