Our Partner Delivery Model

Our Partner Delivery Model

Cass teams with the country’s pre-eminent energy management companies to deliver a complete energy expense management program. We focus on the business process of managing utility invoices, and deliver the data it acquires through this process through our ExpenseSmart® client portal and via partner integrations. Our partners do the heavy lifting of providing critical analysis, advisement, and procurement services, facilitating both long- and short-term initiatives to generate cost savings and reduce environmental impacts.

The Cass model – which allows Cass and its partners to each focus on their own specialized sets of core competencies – has enabled Cass to grow to the largest utility bill processor in the U.S.
