The number on a paycheck is the end of a chain: a deal, a rate, a rule, a validation, sometimes a clawback. Commish keeps the whole chain, for every dollar, every run — so “why did I get this?” is answered by showing, not arguing.

Start at the cycle total, click into a rep, click into a deal, and land on the exact calculation: which component fired, at what rate, on what basis, and which validation checks passed before it was allowed to pay. Nothing is a black box because nothing is allowed to be.

Runs move through review and approval before anything reaches payroll, and the export lands in your payroll provider's format. Integer-cent math end to end: rounding happens at display, never inside the calculation, because a million tiny float errors is still an error on somebody's pay.
Run your real plan and click down to any dollar's receipt.
