Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Calabrio ONE
- Ownership changed in November 2025 when Thoma Bravo took Verint private and merged it with Calabrio, so the product is no longer the independent alternative to Verint that most shortlists put it on for, and roadmap priorities across two overlapping suites will be decided by one company.
- The combined business has run substantial layoffs following the buyout, which raises real questions about support responsiveness and module investment that a prospective buyer should press on in contract negotiation.
- Pricing is quoted per agent per month, commonly cited from around 75 US dollars, with analytics and quality sold as separate modules, so the headline figure understates a full suite deployment considerably.
- There is no free trial and no self-service tier, meaning evaluating the forecasting engine against your own historical data requires a sales-led proof of concept measured in weeks.
- The forecasting and scheduling engine assumes an operations team that can configure shift rules, service level targets and skill routing correctly; deployed by a team without that expertise it produces schedules people override manually, which negates the reason to buy it.
Zendesk
- AI agents operate on per-resolution billing; customers pay only when an AI agent successfully resolves a ticket without escalation
- Copilot and Contact Center features available as separate add-ons at £50+/agent/month
- Advanced routing, workforce engagement, and approval workflows limited to Enterprise tier
- Highest tier requires sales consultation and custom pricing
