Where each one falls short

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

OneSignal

  • Free plan email sends cap at 10,000 per month and web push is capped at 10,000 subscribers per send, per onesignal.com/pricing (Aug 2026)
  • Professional and Enterprise plans require custom annual contracts with no published rate, per onesignal.com; SMS/RCS messaging and dedicated IPs are gated behind the Professional tier
