California Water Service Company - Customer Case Study

California Water Service Company, the largest regulated American water utility west of the Mississippi, needed to move hundreds of millions of dollars in annual AP spend off paper checks and into electronic payments. They engaged Paymerang to provide an automated payments solution to streamline accounts payable and reduce manual processing.

Paymerang implemented the automated payment platform in under 30 days, shifting AP from 100% paper to 92% electronic payments and generating over $1M in rebates across five years. The solution saved more than 2,500 hours of work, improved efficiency and profitability, and turned payment processing from a cost center into a rebate-generating service for California Water Service Company.
