Self-service e-commerce and debt-collection platform for a business-information provider

The client sits at the center of its market's business-information ecosystem. It provides economic and financial information and supports debt collection, which places it in one of the most tightly regulated corners of the financial sector. Handling this kind of data is not like running an ordinary online store: the legal obligations around who may see what, and under what conditions, are demanding, and the penalties for getting them wrong are severe.

That regulatory weight is the backdrop to the whole engagement. The company needed to modernize how it sold and serviced its products, but it had to do so without compromising on data protection or the specific rules governing the disclosure of business information. The prize was significant. A self-service digital channel would let customers transact at any hour and relieve the operational teams of a great deal of manual work. But reaching it meant weaving advanced financial processes, including settlements and commissions, together with debt-collection workflows, inside an environment with very high legal and security requirements, and doing it on top of core systems that had to stay consistent throughout.

The heart of this project was never just a website. It was the integration challenge underneath it. A self-service portal is only as good as its ability to reach into the systems that actually hold the customer's data, process their payments, provision their services, and track their cases. That meant the real engineering lived in the integration layer, connecting a customer-facing portal to a landscape of core financial systems built on different technologies, without ever letting the data between them fall out of sync.

Pretius delivered the portal on the Liferay Portal platform, chosen specifically for its flexibility as a framework for managing content and, critically, the permissions of external users. In a system where different customers may see different data under different legal conditions, fine-grained control over external-user access is not a feature to bolt on later. It is foundational, and it drove the platform choice.

The portal was then wired into the client's core systems through two complementary integration styles. An IBM WebSphere MQ message bus connected it to the billing and provisioning platforms, giving those transactional, asynchronous exchanges the reliability of a proper message queue. Web Services connected it to the CRM and BackOffice systems for the more request-driven interactions. Together these formed a stable enterprise application integration (EAI) layer, the connective tissue that let a single portal act as one coherent front door to many systems behind it.

The engagement was enterprise in scale and ran in multiple stages, beginning with requirements analysis and integration-architecture design in 2011 and progressing through the build of the self-service portal, the MQ and billing integration, the digital contract-signing module, and the financial-reporting module. It was delivered under a fixed-price model for the implementation stages and a time-and-materials model for ongoing maintenance and development, with Pretius acting as the main solution provider across development, analysis, and project management. The scope was deliberately bounded: full core accounting was left to dedicated systems rather than absorbed into the portal, keeping the platform focused on what it did best.

An enterprise financial platform of this kind carries risks that are easy to name in advance and hard to engineer around, and the team went in with a clear view of the three that mattered most.

The client did not simply need a website. It needed a single digital front door that could sell services, sign contracts, take payments, and drive debt collection, all while reaching cleanly into a landscape of core financial systems and never stepping outside demanding data-protection and business-information law. By building the portal on Liferay for its external-user control, wiring it into billing, provisioning, CRM, and BackOffice through a stable MQ and Web Services integration layer, anchoring consistency with an Operational Data Store, and automating debt collection end to end, Pretius delivered exactly that.

The result opened a new e-commerce revenue channel, stripped a great deal of manual work out of operations, gave customers 24/7 control over their reports and cases, and passed the security and compliance audits that the sector demands. It has remained a foundation of the client's online business and a cornerstone of a partnership that has continued for years. For any regulated business trying to digitize a complex, multi-system process, this project is a case in point: the hard part is the integration, and getting it right is what makes everything else possible.
