One number
Finance and merchandising plan against the same model. No reconciliation cycle, no version drift.
Margin protected
Open-to-buy and markdown exposure are visible and enforced before the money is committed, not after.
Board-ready
Every figure traces back to the plan and the data behind it, with an audit log you can't quietly alter.
