The AR Aging Report: A Complete Guide to Protecting Your Cash Flow
An AR aging report organizes every unpaid invoice by how long it has been outstanding, grouped into a current bucket plus 1-30, 31-60, 61-90, and 90+ days past due. This guide covers 2026 benchmarks (80%+ of AR should be current), industry DSO norms, collection probability by age, and how to turn the report into a tiered collection system that protects cash flow.
