Contract Lock-In, Add-On Fees & API Rate Gotchas
Zendesk hides significant costs behind 'Enterprise' tier requirements for advanced AI governance and sandbox environments, often forcing upgrades that double per-seat costs. Intercom's $0.99 per resolution model appears cheap, but the 'outcome' definition is broad; if a customer reopens a ticket, you may be double-billed, and the lack of native voice routing forces reliance on expensive third-party integrations that inflate the monthly bill beyond the advertised seat price.
