Reconciling against the vendor’s own dashboard
Where to look in USPS’s own dashboard: The USPS dashboard surfaces this metric (or its components) under the relevant report section. Confirm period boundaries and filter settings match the Vortex IQ profile to reconcile cleanly. Why the Vortex IQ value may legitimately differ:| Reason | Direction | What to do |
|---|---|---|
| Period boundary. Vortex IQ uses 30-day rolling by default; vendor dashboards may use calendar periods. | Variable | Match the period range. |
| Time zone. Vendor uses account time zone; Vortex IQ aligns to merchant reporting time zone. | Marginal | Confirm time zone match. |
| Filter scope. Profile-level filters (channel, B2B, test orders) may narrow the Vortex IQ view. | Variable | Match filter settings. |
