Five9 vs Plain FAQ

Which one is cheaper?
Plain is the cheaper option, starting at $35/mo vs $119/mo for Five9.
Can I use either one for free?
Neither has a free plan. But Plain offers a free trial.
How do they charge?
Both use a per-seat model, so the comparison is straightforward — it comes down to features and limits at each price point.
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: Foundation undercuts most support-tooling competitors at $35/seat, positioning Plain as the affordable modern alternative for startups and small teams. But Horizon's $299/seat price point pushes them into premium territory fast, so they're really playing a barbell strategy — cheap to get in the door, expensive once you need real firepower.
