Cost Per Invoice Calculator
Measure the true cost to process each invoice, including salaries, benefits, software, supplies, and exception handling overhead.
The average cost to process a single invoice manually is $9.40 according to Ardent Partners, though fully loaded costs at many organizations run higher when you include labor, benefits, overhead, software, and exception handling. APQC benchmarks show best-in-class teams operate below $5 per invoice, while bottom-quartile departments can exceed $30. Understanding your true cost per invoice is the first step toward building a credible automation business case.
Key Industry Data
