Methodology

This calculator estimates revenue leakage based on billing accuracy benchmarks from APQC (American Productivity & Quality Center). Leakage rates reflect industry averages for service businesses: manual billing processes typically experience 3–5% error rates, semi-automated systems 1.5–2.5%, and fully automated billing platforms under 1%. Invoice processing costs are based on APQC median benchmarks for accounts receivable operations. DSO cash flow impact is calculated as the daily revenue rate multiplied by the difference between your current DSO and a 30-day best-practice target, representing the working capital opportunity cost. Actual results depend on invoice complexity, customer payment terms, dispute rates, and the specific billing platform implemented. All calculations run client-side; no data is collected or transmitted.
