Case Study: International SOS achieves end-to-end AP/AR automation and faster collections with Esker

Eliminating Manual Processing To Run a More Efficient Finance Department

International SOS, a global leader in health and security risk management, was struggling with slow, manual finance operations across both accounts payable and accounts receivable. Serving customers through thousands of third‑party providers created a complex flow of supplier invoices (many paper or email submissions), fragmented supporting documents and poor collaboration between AP and AR teams, resulting in long payment cycles, reconciliation issues and slow collections.

To address this, International SOS implemented Esker’s cloud platform—automating Accounts Payable, Invoice Delivery, Collections Management and Cash Application and integrating with its Oracle and SUN6 ERPs. Centralized workflows, an online portal and Esker’s AI-driven matching boosted efficiency: the company now processes 180,000 supplier invoices annually with over 95% electronic invoicing, achieves end‑to‑end visibility, faster collections and more accurate cash application, improving dispute handling and customer relationships.
