How to Format Your Customer Service Representative Resume for ATS
Formatting mistakes cause an otherwise strong resume to score near zero. These are the most important rules for Customer Success ATS systems.
Include ARR/NRR figures explicitly
Write '$X ARR book of business' or 'X% net revenue retention'. CS ATS filter on these exact terms.
Name your CS platforms
Gainsight, Salesforce, ChurnZero, Intercom — not 'customer success tools'. Exact platform matches rank higher.
Include NPS and CSAT scores
ATS in CS roles often search for satisfaction metric terms. 'NPS of X', 'CSAT of X%' should be in your bullets.
Match SaaS-specific terminology
Onboarding, QBR, health score, expansion ARR — these are exact filter terms for CS roles at SaaS companies.
