Modernizing Waterfall Payments for Brookfield Properties
Built a secure web portal replacing MS Access, cutting payment cycle time by 60%.

Project Overview
Brookfield Properties relied on an outdated MS Access database to store its complex ownership hierarchy and generate “waterfall” payment instructions in Excel. That manual process was error-prone, difficult to maintain, and exposed the finance team to compliance risk under Canadian banking regulations. To modernize operations, we built a secure, cloud-hosted web portal that replicates the legacy template output exactly as before—while adding real-time task tracking, role-based security, and a streamlined user experience.
The Challange
Our Solution
We designed and deployed a centralized web portal that lets Brookfield Properties maintain ownership structures, trigger waterfall payment batches on demand, and export FIS Integrity–compatible Excel templates without altering downstream systems. Built with ASP.NET Core and ReactJS, the application integrates OKTA single sign-on for secure access, features intuitive data-entry forms, and runs on Azure for scalability. An Agile delivery model ensured rapid iteration and close collaboration with Brookfield’s finance and IT teams.

Within weeks of launch, the finance team had fully transitioned off the Access-Excel workflow and now executes end-to-end waterfall payments with a few clicks. The portal’s audit trail and reporting features deliver complete transparency for regulators, while IT overhead has dropped by 70%.
