Month-End Close Benchmarks by Industry
How long does month-end close take across industries — and where AP automation makes the biggest difference.
The average month-end close takes 6.4 business days across all industries, but varies significantly by sector. Construction companies average 8.2 days due to complex job costing and retention tracking. Healthcare averages 7.1 days driven by insurance reconciliation complexity. Professional services firms average 5.8 days. Property management companies processing invoices across multiple properties average 7.5 days. AP automation reduces close time by 2–5 days across all industries by eliminating manual invoice reconciliation bottlenecks.
