Case Study: Hall's Culligan achieves 93% AP automation and full process visibility with Esker

Harnessing AI-Powered Automation to Delegate AP Workload & Achieve Process Transparency

Hall’s Culligan Water, a family-owned water treatment company with about 1,000 employees and 43 subsidiaries, faced slow, opaque accounts payable (AP) processes driven by a clumsy legacy automation setup that relied on three separate tools, poor OCR, Java end-of-life, limited user access and weak reporting. The team needed faster processing, full invoice visibility, seamless Sage ERP integration and the ability to delegate work during absences.

By switching to Esker’s cloud AP solution, Hall’s Culligan gained an intuitive, Sage-integrated platform with real-time updates, customizable dashboards, unlimited concurrent users and AI-driven invoice recognition. The change cut support calls, enabled easy task delegation, boosted employee morale and transparency, and delivered a 93% AP automation rate—positioning the company to expand automation further with Esker Expense Management.
