core banking

Temenos upgrades that start with your local developments.

We upgrade Temenos Core Banking, the product long known as Transact and before that T24. That means reviewing local developments, planning moves to Temenos SaaS on Azure or AWS, building integrations and staffing Temenos developers when the bank's bench is thin.

We work on Temenos Core Banking, which Temenos now markets as Temenos Core and many banks still call Transact or T24.

We plan upgrades, inventory local developments and cut them back, prepare moves to Temenos SaaS on Microsoft Azure or AWS, and build integrations to payments, digital channels and data platforms. We also supply Temenos developers and analysts on contract or permanent terms.

what we do

Our Temenos Core Banking work

6 kinds of Temenos Core Banking work, each run by engineers who have done it on live tenants.

  1. A route from your current release to the target, with each local development mapped and a regression pack built from your own products and accounts.

  2. An inventory of local code and configuration, with each item marked keep, replace with base product or retire before the upgrade.

  3. What changes if Temenos runs the platform on Azure or AWS, including interfaces, environments, release rhythm and the testing you still own.

  4. Interfaces to payments, digital banking, card systems, the general ledger and data platforms, built through Temenos APIs with owners per interface.

  5. Licensing, data access and review rules for Temenos AI products such as Copilot for Workbench and the FCM AI Agent.

  6. Temenos developers, business analysts and testers, onsite in the US or from nearshore and offshore teams across time zones.

typical situations

Temenos Core Banking situations we walk into

We pieced these together from Temenos Core Banking situations that come up a lot. They're patterns. You won't find a specific client in them.

case file 01

Hundreds of local developments and an upgrade years overdue

composite · not a client story
  1. Beforethe situation

    A bank runs an old Temenos release with hundreds of local developments, several duplicating features now in the base product. The upgrade has been deferred twice and support costs keep rising.

  2. What we dothe work

    We inventory the local developments and hold each one up against what the target release already does. Duplicates get marked for retirement, everything else for rework. A regression pack built from close-of-business runs is the baseline.

  3. Afterwhere you end up

    Fewer local developments go into the upgrade, and the ones that remain are documented.

case file 02

Screening alert backlog and the FCM AI Agent on the table

composite · not a client story
  1. Beforethe situation

    Watchlist screening throws up more alerts than compliance can clear, and the team is evaluating Temenos's FCM AI Agent. Before relying on it, compliance wants evidence.

  2. What we dothe work

    We take a sample of past alerts that already have analyst decisions, run them through the agent in a test environment and compare. Senior analysts look at every disagreement, and review rules get written from what they find.

  3. Afterwhere you end up

    When compliance decides on the agent, it has a comparison with its own past decisions to go on.

approach

How a Temenos Core Banking engagement runs

We don't start a step until the last one has produced something you can check.

  1. step 01

    Local development inventory

    Every local development, interface and report goes on a list, marked keep, replace with base product, or retire against the target release.

  2. step 02

    Regression baseline

    We build a regression pack out of your products, accounts and close-of-business runs. Run it on the current release and you have a baseline.

  3. step 03

    Upgrade or SaaS plan

    The inventory and baseline become an upgrade or SaaS plan with code changes, interface work and testing durations.

  4. step 04

    Cut-over and handover

    We stay for cut-over and the close-of-business checks that follow. You keep the runbooks, the regression pack and documentation for every piece of local code.

architecture

Where Temenos Core sits in a retail bank

Digital channels and branch systems are the way in. Temenos Core holds the accounts and runs close of business, and its outputs go to payments, the ledger and reporting.

01Is Temenos Transact still the product name?

Temenos's core banking page now uses the name Temenos Core, under a Core Banking heading. T24 was renamed Transact earlier, and many banks still use both older names. We use whichever name your contracts and documents use.

02How long does a Temenos upgrade take?

It depends on how far apart the releases are, how many local developments you carry and how long a full regression run takes. We count local developments first, because they usually set the timeline.

03What changes on Temenos SaaS?

Temenos runs the platform on Azure or AWS and handles updates. The bank still owns product configuration, testing, interfaces and data access decisions, and those have to fit Temenos's release rhythm.

04Do your people hold Temenos certifications?

Temenos trains clients, partners and independents through the Temenos Learning Community, but it doesn't publish its certification names. So we screen people by the modules and releases they've actually worked on.

05Can you help us use Temenos AI features?

Yes. The licence comes first, so we confirm what it includes. Then data access and review rules, like comparing FCM AI Agent results with past analyst decisions before anyone relies on it.
