What commission tracking does inside a CRM
Commission tracking applies your incentive rules to the deals in your pipeline and keeps the result current. Instead of exporting data at month end and rebuilding the calculation, the payout is a property of the deal: this deal closed at this value, owned by this rep, under this rule, worth this amount.
That change of location matters more than it sounds. When the calculation lives where the deals live, it is visible to the person it affects, it updates when a deal is amended, and it reverses when a sale is cancelled. Most commission disputes are not about the rate. They are about a number that appeared with no working shown.
