How to Run a Churn Audit: A Step-by-Step Guide

You know churn is a problem. You're not sure exactly why. A churn audit gives you the answer.

What a churn audit delivers

A churn audit answers five critical questions:

  1. Who is churning? Which segments, cohorts, and customer profiles?
  2. When are they churning? At what point in the lifecycle?
  3. Why are they churning? What are the root causes?
  4. What did we miss? Were there signals we could have caught earlier?
  5. What do we do? What actions will reduce churn going forward?

Before you start

Gather your data sources

Source What it provides
CRM Customer details, deal history, renewal dates, CSM notes
Billing system Revenue history, upgrades, downgrades, cancellations
Product analytics Usage data, feature adoption, login frequency
Support platform Ticket volume, resolution times, escalations, CSAT
Customer feedback NPS scores, survey responses, churn reasons
CS notes QBR notes, call summaries, risk flags, health assessments

Define your timeframe

Analyse 12-24 months of churn data. Less than 12 months won't give you enough pattern visibility. More than 24 months may include data from a fundamentally different stage of your company.

Assemble your team

A churn audit requires cross-functional input. Include:

Step 1: Quantify the churn

Metrics to calculate

Segment by

Look for segments where churn is significantly above or below average. These outliers tell you where to focus.

Step 2: Identify patterns

Timeline analysis

Churn Timing Likely Root Cause
0-3 months Onboarding failure, misset expectations, poor ICP fit
3-6 months Value not realized, adoption stalled, use case mismatch
6-12 months Usage declined, champion left, competitor emerged
12+ months Contract re-evaluation, budget cuts, strategic shift, vendor consolidation

Renewal analysis

What percentage of customers who enter a renewal cycle actually churn? How many downgrade? How does this vary by segment? Track renewal outcomes over time to identify whether the problem is getting better or worse.

Contraction analysis

Contraction often precedes full churn. Customers who downgrade once are significantly more likely to churn at next renewal. Track the churn rate of previously-contracted accounts separately.

Step 3: Diagnose root causes

Categorize stated reasons

Validate with behavioral data

Stated reasons don't always match reality. Cross-reference with behavioral signals:

Stated Reason Behavioral Validation
"Too expensive" Was usage actually declining? Were they using key features?
"Missing features" Did they submit feature requests? Were workarounds available?
"Poor support" What was their ticket volume, resolution time, CSAT?
"Switched to competitor" When did evaluation start? What triggered it?

Build the root cause breakdown

Root Cause % of Churned ARR Preventable? Priority
Poor ICP fit 25% At point of sale High
Onboarding failure 20% Yes High
Product gaps 20% With roadmap investment Medium
Champion loss 15% With multi-threading Medium
Competitive displacement 10% Partially Medium
Business closure/M&A 10% No Low

Step 4: Analyse the misses

Audit leading indicators

For each churned account, look back 90 days before the churn event. What signals were present?

Signal Present 90 days before churn?
Usage decline (>20% drop) Check product analytics
Support ticket spike Check support platform
NPS/CSAT decline Check survey data
Champion role change Check CRM contacts
Missed QBR/check-in Check CS calendar
Login frequency drop Check product analytics
Feature adoption stall Check product analytics
Payment issues Check billing system

Calculate predictability

Identify gaps

For churns without visible signals, ask: What data would we have needed? Is it available but not tracked? Does it require a new data source? This tells you where to invest in instrumentation.

Step 5: Build the action plan

Prioritization framework

Score each potential action on three dimensions:

Example action plan

Action Root Cause Addressed ARR Impact Timeline Owner
Implement ICP scoring in sales process Poor ICP fit $125K 30 days Sales Ops
Redesign onboarding for time-to-value Onboarding failure $100K 60 days CS Leadership
Build automated health score alerts Late detection $75K 45 days RevOps
Launch champion tracking program Champion loss $75K 30 days CS
Prioritize top 3 feature gaps Product gaps $100K 90 days Product

Set targets

Metric Current Target Timeline
Gross Revenue Retention 88% 92% 12 months
Logo Retention 82% 88% 12 months
At-risk detection rate 45% 75% 6 months
Time-to-value (days) 45 21 6 months
Save rate (at-risk accounts) 20% 40% 9 months

The audit cadence

Cadence Activity
Weekly Review at-risk accounts, track leading indicators, execute save plays
Monthly Analyse churn/contraction events, update root cause breakdown, assess action plan progress
Quarterly Full cohort analysis, segment deep-dives, action plan refresh, target assessment
Annually Complete churn audit refresh, strategy review, investment planning

The deliverable

Your churn audit should produce six outputs:

  1. Churn summary — headline metrics, trends, and segment breakdowns
  2. Pattern analysis — when churn happens, who it affects, and how it manifests
  3. Root cause breakdown — weighted analysis of why customers leave
  4. Predictability assessment — how much churn was detectable in advance and what signals matter
  5. Action plan — prioritized initiatives with owners, timelines, and expected impact
  6. Targets — specific, measurable goals with timeframes for accountability
