Read first

  1. Net revenue retention and churn for your book
  2. Book size
  3. Expansion and adoption results
  4. Onboarding and health processes

One line, before and after

  • Original: Managed 60 mid-market accounts worth $4.5M ARR. Gross retention was 96% and expansion added $510K in 2025.Suggested: Managed 60 mid-market accounts ($4.5M ARR) with 96% gross retention and $510K in expansion in 2025.

Section order

  1. Summary with book size
  2. Experience

Where your resume has these sections. A section your resume does not have is not added.

Mistakes that cost interviews

  • Relationship words with no retention numbers
  • Relationship words without outcomes
  • Revenue effects attached to support work

Evidence that counts in customer success and support

  • Retention and renewals for success roles, as documented
  • Book of business size and segment
  • Ticket volume, resolution and satisfaction for support roles
  • Escalations and technical work
  • Tools used

Use what your resume already shows. A line without a number can still be strong when it says clearly what you did and where.
