Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Five9

  • A 50 seat minimum applies to the published rates, so the entry cost on the $119 Digital plan is $5,950 a month
  • Prices are per concurrent user rather than per named agent, which changes what a seat means when shifts overlap
  • Voice is excluded from the Digital plan and requires a quote
  • Usage based charges apply on top of the per seat rate
  • Three of the five tiers publish no price at all

Optimizely

  • No pricing is published and no minimum is stated
  • Every plan is individually packaged, so no two quotes are necessarily comparable
  • Reaching a figure requires a demo or sales conversation
