Interview Questions › Root Cause Analysis

SaaS churn increased for SMBs but not Enterprise

Your B2B SaaS platform saw monthly logo churn jump from 2.1% to 4.8% for SMB customers (<50 seats), while Enterprise churn remained record-low (<0.5%). Diagnose why.

Context

A new quarterly pricing tier restructured seat add-ons and automated onboarding workflows 3 months ago.

Clarifying questions to ask first

• Are churning SMBs cancelling in Month 1-3 (onboarding failure) or Month 12 (renewal)?
• Did product usage decline prior to cancellation?

How to approach it

1. Segment SMB customers by Onboarding Maturity (Self-serve vs CSM-assisted), Plan Tier, and Industry Vertical
2. Analyze feature usage depth: Daily active users per workspace, integration connectivity, and automation recipe runs
3. Evaluate the impact of the new minimum seat pricing policy on small businesses
4. Examine macro economic conditions (SMB budget cuts vs tooling consolidation)

Framework: Customer Cohort Segmentation -> Pricing & Packaging Changes -> Onboarding & Product Value Realization -> Support & CSM Touchpoints

Sample answer

• Removal of free human onboarding for SMB tier led to low activation
• Price restructuring increased base entry tier from $50/mo to $180/mo upon renewal
• Simpler lightweight competitor launched a freemium tool targeting SMB niche

1. 80% of churn happened at Month 2; accounts with 0 integrations had 6x higher churn
2. Self-serve onboarding redesign skipped Zapier/Slack integration step, leaving SMBs without automated workflows

Automated onboarding redesign skipped critical CRM integrations; built guided interactive setup checklists and introduced quarterly flexible SMB tiers.
