The short version

  • Each has a real cost: Adyen there is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic; 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.
  • They diverge on capability: Adyen covers Payment processing, Temenos Transact covers Country model banks.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Adyen

  • There is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic
  • Published fees are indicative rather than a rate card, with real pricing negotiated
  • Interchange++ means the card cost varies per transaction rather than being a single predictable percentage
  • Alternative payment methods carry their own rates on top, such as 3.3 percent plus $0.10 for American Express in North America

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.

Temenos Transact: Is Transact the same as T24?

Yes. T24 was renamed Temenos Transact; older installations and much of the consultant population still use the T24 name.

Adyen: Does Adyen have monthly subscription or setup fees?

No, Adyen has no setup fees or monthly recurring charges. You pay only for each transaction processed. The transaction fee structure remains the same regardless of transaction volume or business size.

Source
Temenos Transact: Can it run in the cloud?

Yes, it is offered on public cloud, though many existing installations remain on-premises and moving them is a project.

Adyen: What's Adyen's Interchange++ pricing option?

Adyen offers an Interchange++ transparent pricing model that passes interchange and scheme fees directly to merchants instead of bundling them into a percentage rate. This allows visibility into exact costs for each payment method.
