Each metric has its own page: definition, calculation, why it matters, and what to do when it moves. The Amazon Prime Shipping (SFP) connector brings the Vortex IQ **AI OS** to merchants enrolled in Seller Fulfilled Prime - shipping their own warehouse stock to Prime customers under Amazon's strict 1-day / 2-day delivery promise and 99% OTD threshold. The **Nerve Centre** tracks 25 KPI pulses with hero alerts on *Avg Shipping Cost*, *On-Time Delivery Rate*, *SFP On-Time Delivery vs 99% Threshold*, *Prime 1-Day / 2-Day Promise Miss Rate*, *Late Shipments*, *Exception Rate*, *Open Claims*, *Days to Token Expiry*, plus cross-platform *Late-Shipment Buy Box Loss* and *SFP Eligibility Risk by ASIN* - because losing Prime eligibility loses the listing. **Vortex Mind** investigates when ASINs trend toward the 99% breach line; **Ask Viq™** answers in plain English with citations back to the order. | Card | Metrics type | Category | Chart | | --------------------------------------------------------------------------------------------------------------------------- | ---------------------- | ------------------------------- | --------------- | | [Avg Shipping Cost](/nerve-centre/kpi-cards/amazon-prime-shipping/avg-shipping-cost) | Key Metrics | Cost & Efficiency | kpi | | [Days to Token Expiry](/nerve-centre/kpi-cards/amazon-prime-shipping/days-to-token-expiry) | Key Metrics | Operational Health | kpi | | [Exception Rate](/nerve-centre/kpi-cards/amazon-prime-shipping/exception-rate) | Key Metrics | Exceptions & Claims | gauge | | [Late Shipments](/nerve-centre/kpi-cards/amazon-prime-shipping/late-shipments) | Key Metrics | Delivery Performance | kpi | | [On-Time Delivery Rate](/nerve-centre/kpi-cards/amazon-prime-shipping/on-time-delivery-rate) | Key Metrics | Delivery Performance | gauge | | [Open Claims](/nerve-centre/kpi-cards/amazon-prime-shipping/open-claims) | Key Metrics | Exceptions & Claims | kpi | | [Prime 1-Day / 2-Day Promise Miss Rate](/nerve-centre/kpi-cards/amazon-prime-shipping/prime-1-day-2-day-promise-miss-rate) | Key Metrics | Delivery Performance | gauge | | [SFP On-Time Delivery vs 99% Threshold](/nerve-centre/kpi-cards/amazon-prime-shipping/sfp-on-time-delivery-vs-99-threshold) | Key Metrics | Delivery Performance | gauge | | [Late-Shipment Buy Box Loss](/nerve-centre/kpi-cards/amazon-prime-shipping/late-shipment-buy-box-loss) | Cross-Platform Metrics | Cross-Platform: Revenue at Risk | kpi | | [SFP Eligibility Risk by ASIN](/nerve-centre/kpi-cards/amazon-prime-shipping/sfp-eligibility-risk-by-asin) | Cross-Platform Metrics | Cross-Platform: Revenue at Risk | alert\_table | | [API Error Rate](/nerve-centre/kpi-cards/amazon-prime-shipping/api-error-rate) | Supporting Metrics | Operational Health | gauge | | [Avg Transit (days)](/nerve-centre/kpi-cards/amazon-prime-shipping/avg-transit) | Supporting Metrics | Delivery Performance | kpi | | [Claim Value (open)](/nerve-centre/kpi-cards/amazon-prime-shipping/claim-value) | Supporting Metrics | Exceptions & Claims | kpi | | [Cost by Zone](/nerve-centre/kpi-cards/amazon-prime-shipping/cost-by-zone) | Supporting Metrics | Cost & Efficiency | bar\_horizontal | | [Cost Per Shipment Trend](/nerve-centre/kpi-cards/amazon-prime-shipping/cost-per-shipment-trend) | Supporting Metrics | Cost & Efficiency | sparkline | | [Failed Deliveries](/nerve-centre/kpi-cards/amazon-prime-shipping/failed-deliveries) | Supporting Metrics | Exceptions & Claims | kpi | | [First-Attempt Delivery Rate](/nerve-centre/kpi-cards/amazon-prime-shipping/first-attempt-delivery-rate) | Supporting Metrics | Delivery Performance | gauge | | [High-Cost Shipment Outliers](/nerve-centre/kpi-cards/amazon-prime-shipping/high-cost-shipment-outliers) | Supporting Metrics | Cost & Efficiency | table | | [Label Generation Success](/nerve-centre/kpi-cards/amazon-prime-shipping/label-generation-success) | Supporting Metrics | Operational Health | gauge | | [OTD by Route](/nerve-centre/kpi-cards/amazon-prime-shipping/otd-by-route) | Supporting Metrics | Service Mix | bar\_horizontal | | [Returned to Sender](/nerve-centre/kpi-cards/amazon-prime-shipping/returned-to-sender) | Supporting Metrics | Exceptions & Claims | kpi | | [Shipments](/nerve-centre/kpi-cards/amazon-prime-shipping/shipments) | Supporting Metrics | Volume | kpi | | [Shipments by Destination](/nerve-centre/kpi-cards/amazon-prime-shipping/shipments-by-destination) | Supporting Metrics | Service Mix | geo\_map | | [Shipments by Service](/nerve-centre/kpi-cards/amazon-prime-shipping/shipments-by-service) | Supporting Metrics | Service Mix | pie | | [Shipments Over Time](/nerve-centre/kpi-cards/amazon-prime-shipping/shipments-over-time) | Supporting Metrics | Volume | line | *Appendix space for FAQs, reconciliation guidance, or cross-connector notes specific to this connector.
