Concourse supports user-defined business rules that can be configured and made available to the business services during transaction processing. These rules allow a business service, like Fees & Commissions or Extended Settlement, to invoke custom methods of processing without the time and expense of custom software development. As a company's business needs change, rules may be altered and new rules implemented without code modifications or software outages.

The Concourse rules engine has a number of unique attributes that make it ideally suited for large transaction volumes and the complexities of EFT transactions. Specifically these features include

Browser-based graphical rules builders provide an intuitive, step-by-step process for the creation and modification of business rules. The point-and-click selection of appropriate rule attributes replaces the programming complexity of traditional rules engines without compromising the sophistication of the resulting business rules.

A significant benefit of the Concourse rules engine is the delivery of flexibility without reduced runtime performance. Concourse automatically compiles the configured business rules into executable libraries for use during runtime processing. The automated compilation of new rules results in significantly better performance than traditional interpretive rules systems. No software outage is needed for the system to start using a new version of rules.
