  • They diverge on capability: Dwolla covers ACH transfers, 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.

Dwolla

  • Nothing is published: there are no per-transaction rates, no platform fee and no minimum on the pricing page, so every buyer negotiates blind and small platforms have no way to sanity check what they are quoted.
  • It is payments only, with no deposit accounts, card issuing or general ledger, so companies embedding financial products need at least one further vendor and the reconciliation between them.
  • Instant payment reach depends on the receiving institution supporting RTP or FedNow, so a meaningful share of payouts still fall back to ACH timing regardless of what the API can do.
  • ACH returns and administrative returns remain your operational problem, and platforms new to bank rails routinely underestimate the customer support load that failed debits generate.
  • Access to instant rails runs through Dwolla banking partner, which reintroduces a bank dependency into a product that otherwise avoids sponsor bank programme risk.

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.

Answered from the vendors’ own pages

Dwolla: What does Dwolla cost?

It does not publish anything. Pricing is custom and built around volume, rails and integration. Establish the monthly platform fee and any minimum before negotiating per-transaction rates.

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.

Dwolla: Does it support instant payments?

Yes, through both the RTP network and the FedNow Service, with automatic selection based on the receiving bank. Where neither is supported, payments fall back to ACH.

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.

Dwolla: Is Dwolla a bank?

No. It is a payments platform that works through banking partners. It does not offer deposit accounts or card issuing.

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.

Dwolla: How does bank account verification work?

Either instantly through open banking connections or by micro-deposit verification, which takes a day or two but works where instant linking fails.
