How do they charge?

Which one is a better deal?

Depends on what you need. Five9: With a 50-seat minimum and no published pricing past $159, Five9 is clearly chasing mid-market and enterprise contact centers, not SMBs — they're competing with the likes of NICE and Genesys on capability, not with cheaper self-serve tools like Talkdesk's lower tiers. Plain: At $35 entry, Plain undercuts most established helpdesk tools to hook smaller teams, but the leap to $299 for Horizon puts them solidly in premium territory compared to typical mid-market support platforms. They're playing a barbell strategy — cheap enough to poach teams off spreadsheets or basic tools, expensive enough at the top to compete for accounts that'd otherwise go to Zendesk or Intercom.
