Revenue Concentration

Aggregates nonnegative supplied revenue by customer label and computes customer shares, top-one/top-three share and a concentration index. Assumes one period and currency; excludes refunds and does not predict business risk. Uses explicitly supplied structured inputs. Server computations are transient; the standalone website computes locally in your browser. Review the output before exporting it. No persistent account records, external source retrieval, sending, transactions or paid model calls. CSV/JSON review and export are available on the standalone website. MCP requests are capped at 128 KiB and computed responses at 256 KiB; individual field and record limits also apply.
