Case Study: Pattern Energy Group achieves 71% auto-approvals and reclaims 355 audit hours with AppZen

Pattern Energy reclaims auditor time with 71% auto-approvals

Pattern Energy Group, a privately owned renewable energy company with operations in the US, Canada, the Netherlands, and Japan, faced a time-consuming, highly manual expense-auditing process that strained its eight-person Accounts Payable team and risked gaps in government compliance. To automate without disrupting global operations, Pattern Energy Group selected AppZen’s Expense Audit to bring stronger checks and faster reviews to its travel and expense workflow.

AppZen deployed Expense Audit in under two months, enabling Pattern Energy Group to reclaim about 355 auditing hours annually (roughly one full-time equivalent) and auto-approve 71% of expense reports globally. The AppZen solution let the team focus on policy optimization, employee training and fraud investigations, while providing a scalable, compliance-first expense management capability to support the company’s international expansion.
