OLYMPIC Banking System Support.
Deep expertise, senior delivery.

OLYMPIC Banking System is our primary platform. We have spent years working inside it as senior consultants and specialists — supporting live environments, implementing new modules, and managing migrations. When your Core Banking runs on OLYMPIC, we are the external team that already knows it.

What is OLYMPIC Banking System?

OLYMPIC Banking System — developed by ERI Bancaire, now part of Olympic Banking Group — is a proven Core Banking platform used by retail banks, private banks and microfinance institutions across Europe, the Middle East and Africa.

It covers the full banking lifecycle: current accounts, savings, loans, trade finance, treasury, and e-banking via OLYWEB. Its strength is its flexibility: highly parametrisable, it can be configured to match the specific operational model of almost any bank.

That flexibility is also a challenge. OLYMPIC's depth means banks often depend on one or two internal specialists who hold all the institutional knowledge. When they leave — or when the bank needs to grow — the gap becomes critical. That is where Onirem steps in as your dedicated OLYMPIC Banking System specialist.

Who typically needs us

The OLYMPIC-dependent bank

Regional and community banks with 3–50 branches, running OLYMPIC Banking System as their Core. Often with a lean IT team that manages infrastructure — but not Core Banking parameterisation. They need a trusted external OLYMPIC Banking consultant they can call directly.

OLYMPIC Banking System is installed across dozens of institutions globally. Most of them have fewer internal OLYMPIC specialists than they need. We solve that problem — without the overhead of hiring full-time.

Our OLYMPIC Banking System services.

Every engagement is delivered by senior OLYMPIC Banking consultants who have worked with OLYMPIC Banking System in production environments. No juniors, no learning curve.

OLYMPIC Banking System ongoing support

A retainer-based support model for banks that need reliable, expert OLYMPIC coverage without maintaining a full internal team. We handle incidents, change requests, parametrisation queries and user escalations — typically within one business day.

System parametrisation

OLYMPIC's power lies in its parameterisation layer. We configure and tune the system to match your bank's products, workflows and regulatory requirements — from account structures and interest calculation rules to transaction codes and reporting parameters.

OLYMPIC Banking implementation — new modules

Activating a new OLYMPIC module — trade finance, loans, multicurrency, standing orders — requires deep knowledge of the platform's internal logic. We scope, configure, test and hand over new modules with full documentation.

OLYMPIC Banking migration

Whether you are migrating to OLYMPIC from a legacy system or moving between OLYMPIC versions, we manage the full cycle: data mapping and cleansing, parallel run coordination, user acceptance testing, cutover and post-go-live stabilisation.

Reporting & data extraction

Custom report development using OLYMPIC's reporting tools and external BI integrations. Regulatory reporting, management dashboards, audit trails and reconciliation outputs — built to your bank's specifications.

OLYWEB e-banking support

Support and configuration of OLYWEB, the e-banking front-end of OLYMPIC Banking System. User management, product display configuration, integration troubleshooting and performance issue resolution.

Testing & quality assurance

Independent functional and regression testing for OLYMPIC environments — before a go-live, after an upgrade or when releasing new parametrisation into production. We design test plans, execute them and document results.

Troubleshooting & incident resolution

When something breaks in production, speed matters. We diagnose OLYMPIC issues quickly — whether they are parametrisation errors, data anomalies, integration failures or upgrade regressions — and restore normal operation.

User training & documentation

Practical, hands-on training for banking operations staff — built around your bank's specific OLYMPIC setup, not generic vendor slides. Available in English, French and Spanish, remotely or on-site.

How an OLYMPIC Banking System engagement begins.

We don't send generalists who will learn OLYMPIC at your expense. Every engagement starts with senior OLYMPIC Banking consultant involvement and ends with your team better equipped than before.

01

Discovery call

We speak directly with the relevant people at your bank — IT director, operations manager or CFO — to understand your OLYMPIC environment, your pain points and what you actually need. No sales intermediaries.

02

System assessment

For new engagements, we review your OLYMPIC setup — version, modules in use, existing parametrisation, integrations. This gives us the baseline we need to propose accurately and start effectively.

03

Fixed-scope proposal

We produce a written proposal with a defined scope, deliverables and cost. No open-ended time-and-materials that balloon. For support retainers, we define what is included and what falls outside.

04

Engagement & knowledge transfer

We work alongside your team, document everything we do, and ensure your internal staff understand what was changed and why. Dependency on us should reduce over time, not increase.

Engagement models

Retainer support
A monthly engagement for ongoing OLYMPIC Banking System support and maintenance. We are available as your external OLYMPIC team for incidents, change requests and parametrisation work. Ideal for banks without an internal OLYMPIC specialist.

Project-based
A defined scope, timeline and deliverables. Used for OLYMPIC Banking implementation projects, migrations, upgrades and QA. Fixed fee or milestone-based billing.

Ad-hoc advisory
For banks that need occasional expert input — a second opinion on a parametrisation decision, help troubleshooting a specific issue, or guidance before a major change.

"When the bank's only OLYMPIC expert resigned, we had three days to find an alternative. Onirem was on a call with us the next morning."

Banks that work well with Onirem.

🏦

Regional commercial banks

Banks with 3–50 branches running OLYMPIC as their Core, with a lean IT team focused on infrastructure rather than Core Banking configuration. They need reliable external OLYMPIC Banking System support on a retainer or project basis.

Microfinance institutions

MFIs that adopted OLYMPIC Banking System to manage their loan portfolios and client accounts. Often operating in emerging markets with limited local OLYMPIC expertise available, they benefit from remote support arrangements.

Banks mid-migration

Institutions in the process of OLYMPIC Banking migration from a legacy Core Banking system, or between OLYMPIC versions. They need a partner who can manage the technical and functional complexity of the migration itself.
