What is a Financial Ecosystem?

Billions of dollars are lost annually due to the inadequate adoption of fintech technology for financial transactions management whereby mismanaged, aging receivables quickly turn revenues into bad debt and ultimately into losses. The primary reason for this outcome is the lack of a single enterprise solution that can manage every aspect of the revenue management life cycle process across all business units in unison.

Traditional platforms are stand-alone, independent systems that don't share common technology & can’t communicate dynamically with one another, leaving business units separated. This leaves entities with old, stale financial data, making it impossible to both manage aging receivables & avoid uncollectable debt. A Financial Ecosystem resolves this problem. A Financial Ecosystem is a battery of highly sophisticated proprietary fintech systems & solutions that consolidate into one single Financial Platform across your enterprise. HD™ 2.0 | Enterprise Financial Ecosystem® is that end-to-end financial platform that manages your revenues and receivables, while safeguarding bad debt exposure.

Parts of a Financial Ecosystem


HD™ 2.0 | LMS® Loan Management System (LMS) enables credit grantors & servicers to create business rules for underwriting decisioning workflows simply & visually without the need of complicated coding. LMS can systematically control financial screen navigation, input/output, verbose messaging and database interactions from any internal or external system or framework.

Now, when new applications for underwriting are introduced, they are first “interrogated” by the LMS business rules engine, which then gives a “thumbs up, thumbs down” decision.

This approach enables organizations to evaluate the application against multiple internal or external data sources and predict which applications should be manually reviewed, versus those that are most expected to contain appropriate information for automatic underwriting.

HD™ 2.0 | LMS® offers:

  • Automation of manual procedures and calculations: By utilizing an automated analytic-based underwriting system, the consistency, quality and capacity of underwriting could be dramatically improved, allowing underwriters to focus on the exceptions.
  • Control by business users: Rules are designed in an easy-to-understand visual Visio-like workflow designer, enabling the business experts— rather than technical staff—to control and automate procedures and policies.
  • Faster response to change: Time-to-market for business logic changes are reduced from weeks and months to days or hours. Systems can be updated while in production with no down time and no need for IT resources.
  • Increased reliability and auditability: A centralized workflow decisioning rules repository provides consistent execution of business policies that are easy to manage and visually easy to audit.

HD™ 2.0 | LMS® business rules engine allows for the development and rapid deployment of complex credit granting business rules, so your organization can make better decisions across the Revenue Life Cycle. Automate and optimize numerous types of business decisions, including credit approve/decline, instant prescreen offers, and collection decisions.

With HD™ 2.0 | LMS® you can also systematically analyze scoring, business rules and decision strategies from external data systems. This enables continuous testing and fine tuning of your business rules, so you can optimize decision strategies to drive higher profits.

  • Pull data from multiple sources — both internal and external — into your decisioning engine dynamically.
  • Process a high volume of transactions, with support and availability 24 hours a day
