Apexanalytix 2026 Global Overpayment Report

Where Do Your Overpayments Actually Start?

Insights from our analysis of $3.25 trillion in spend and over 400 million invoices from a cross-section of the world’s largest companies.

apexanalytix helps AP and shared services teams find and stop overpayments before and after cash goes out the door, using AI-driven analysis and supplier intelligence built on more than 35 years of audit expertise.

Most AP teams assume overpayments are an AP problem. The data says otherwise. The 2026 apexanalytix Global Overpayment Report identifies the leading causes of overpayments and shows why so many originate upstream of AP, where they rarely get caught before cash goes out the door.

This report gives AP and shared services leaders a benchmark for their own environment against patterns found across a global cross-section of large enterprises, along with a clearer view of where to focus recovery and prevention efforts.

What you’ll learn:

1. The five most common causes of overpayments in large organizations

2. Why overpayments so often stem from issues outside AP’s line of sight

3. How your AP environment compares to benchmarks drawn from the world’s largest companies
