One-formula-for-two-reports error

Applying customer payment plus discount minus tax to Seller Center GMV overstates the declared GMV in the default example from USD 100 to USD 102. Applying customer payment alone to Ads Manager gross revenue omits its discount and tax bridge.

Use the explicit revenue-definition selector and test its declared value. A report title alone is insufficient evidence.

GMV Max paid-only inference error

Product GMV Max can attribute every paid and organic order for selected products while the campaign is active, even without an ad view or click. Calling that total paid-only incremental GMV creates a scope error.

Record campaign-active dates, selected products, paid-plus-organic attribution, and excluded inference. Do not force its ROI into a paid-only contribution comparison.
