Reconciling against the vendor’s own dashboard

Time zone. Vendor uses account time zone; Vortex IQ aligns to merchant reporting time zone.MarginalConfirm time zone match.
Filter scope. Profile-level filters (channel, B2B, test orders) may narrow the Vortex IQ view.VariableMatch filter settings.

Known limitations / merchant FAQs

Q: How often does Active Subscribers (Est.) update? The card refreshes on the standard data refresh (typically every 30-60 minutes for live integrations). For real-time signals, force a manual refresh from the dashboard. Q: Why does my Nimble dashboard show a different number? The most common reasons are period-boundary differences (Vortex IQ uses 30-day rolling vs vendor’s calendar months), time-zone alignment, and filter scope (profile-level vs vendor’s all-account view). Match these settings before assuming a real divergence. Q: How does Active Subscribers (Est.) relate to other customer lifecycle metrics? Track this card alongside the siblings listed above to build a complete picture. Single-metric reads can mislead; the diagnostic value is in the cross-reference. Q: Can I customise the alert threshold? Yes, sensitivity thresholds are configurable per profile in the Sensitivity tab. Adjust to match your business baseline rather than relying on the generic default.
