Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Temenos Transact

  • The codebase originates in the 1990s, so banks on older releases face major upgrade programmes to reach current versions, and many defer them for years.
  • Total cost is dominated by implementation partner fees rather than licence, and those programmes routinely overrun their original estimates.
  • Product changes that cloud-native cores treat as configuration can require development work and a release cycle, which slows time to market for new products.
  • Heavy customisation is common and it makes every subsequent upgrade harder, creating a compounding cost that banks feel a decade after go-live.
  • Temenos has repeatedly restructured its product line and naming, so buyers must check carefully which components a proposal actually includes and which are separately licensed.

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
