GT9 Pricing Tool

Developer

Prevents pricing chaos by enforcing a transparent ruleset and a repeatable quoting flow.

Logic Breakdown

Applies tiering, discounts, and constraints; computes total and produces a quote summary. Rule versioning supports sales enablement updates without breaking historical quotes.
