The short version

  • Each has a real cost: 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.; Really Simple Systems the vendor's own pricing page as captured by the Internet Archive on 22 October 2019 listed four CRM tiers billed annually: Free at $0 for up to 2 users, Starter at $14 per user per month, Professional at $30 per user per month, and Enterprise at $46 per user per month (each roughly 7 to 10 percent higher if billed monthly); the Marketing add-on was $22 per month for up to 5,000 emails and Advanced Marketing scaled to 50,000 emails per month, though this capture is over five years old

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.

Really Simple Systems

  • The vendor's own pricing page as captured by the Internet Archive on 22 October 2019 listed four CRM tiers billed annually: Free at $0 for up to 2 users, Starter at $14 per user per month, Professional at $30 per user per month, and Enterprise at $46 per user per month (each roughly 7 to 10 percent higher if billed monthly); the Marketing add-on was $22 per month for up to 5,000 emails and Advanced Marketing scaled to 50,000 emails per month, though this capture is over five years old
