This nonprofit medical center operates an 880+-bed hospital, as well as a multispecialty academic healthcare science center. It employs a staff of more than 12,000 who care for a diverse community in one of the largest cities in the US. The organization is committed to pioneering medical research achievements and to quality innovations that are helping to define the future of healthcare.


The medical center’s accounts payable team processes more than a billion in payments each year. As part of their commitment to continuous improvement, team leaders wanted to audit their work to look for duplicate payments and unapplied statement credits. They decided to examine nearly four years of payment activity spanning $7 billion in spending.


A team of expert auditors from apexanalytix used artificial intelligence technologies to audit the organization’s accounts payable activity. As a result, they were able to analyze data and make recoveries faster than with a traditional, manual review. They also were able to mine for insights that could protect future disbursements and keep the medical center’s accounts payable team on the path to peak performance.
