The short version

  • Each has a real cost: 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.; Unit your product depends on a sponsor bank you do not contract with directly, and 2024 showed what that means: Thread Bank received an FDIC enforcement action naming its banking as a service programmes and Blue Ridge Bank went under an OCC consent order and offboarded fintech partners.
  • They diverge on capability: Temenos Transact covers Country model banks, Unit covers Deposit accounts.
  • 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.

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.

Unit

  • Your product depends on a sponsor bank you do not contract with directly, and 2024 showed what that means: Thread Bank received an FDIC enforcement action naming its banking as a service programmes and Blue Ridge Bank went under an OCC consent order and offboarded fintech partners.
  • Programme approval by the bank is a separate gate from signing with Unit, and it can add months and impose product restrictions that were not visible during the commercial conversation.
  • Compliance obligations are shared but the operational load lands on you, and platforms consistently underestimate the staffing needed for disputes, escalations and the bank ongoing oversight requests.
  • Pricing is unpublished and blends platform fees, per-account and per-transaction charges and interchange sharing, which makes it hard to model unit economics before you have volume and easy to be surprised by the minimum.
  • Migrating a live deposit programme to a different provider or bank is extremely disruptive because it involves moving customer accounts and card credentials, so switching costs are far higher than for ordinary software.

Answered from the vendors’ own pages

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.

Unit: Who actually holds the money?

A chartered partner bank, not Unit. Deposits sit at the sponsor bank and FDIC insurance flows from that bank, so its condition is your condition.

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.

Unit: What happened with Unit sponsor banks in 2024?

Thread Bank received an FDIC enforcement action that explicitly named its banking as a service and lending as a service programmes, and Blue Ridge Bank was under an OCC consent order from January 2024 and offboarded fintech partners. Blue Ridge exited the order in late 2025.

Temenos Transact: What drives the cost?

Licence scaled by size, annual maintenance as a percentage of licence, and implementation partner fees that usually exceed the software cost.

Unit: What does Unit cost?

Not published. Expect a platform fee, per-account and per-transaction charges, an interchange share and a minimum commitment.

Unit: Do we need our own compliance team?

Yes. Unit supplies tooling and the bank sets the rules, but disputes, escalations and evidence for bank oversight require named people on your side.
