What the Vortex IQ Amazon Prime Shipping (SFP) health audit checks: Amazon Prime Shipping (SFP): Eligibility Risk, 99% OTD Threshold & Buy Box Impact

Nerve Centre KPIs · Audit Profile · Sentiment Settings

Amazon Prime Shipping is the Seller-Fulfilled Prime (SFP) program letting merchants offer Prime-badge delivery on their own Amazon listings. The eligibility bar is brutal: >=99% on-time delivery, <0.5% cancellation, and 1-day/2-day promise compliance. Findings here either lose the Prime badge (catastrophic for Buy Box + conversion) or burn cash through claim ageing. CloudHub probe shows 6 active merchants on the LWA OAuth2 stack shared with the main Amazon SP-API integration. Cross-references amazon.listing via ASIN; commerce siblings via order_ref.

What this audit checks

Authentication & access

• LWA refresh_token still issues access_tokens (no 401)
• Token cache hit-rate > 95%
• Marketplace ID maps to a region with SFP enabled
• Seller ID has Prime-Shipping role granted

SFP eligibility threshold (the eligibility-defining area)

• 30-day SFP OTD < 99% (Prime-badge revocation risk)
• 30-day Prime 1-day promise miss rate > 1%
• 30-day Prime 2-day promise miss rate > 1%
• Cancellation rate > 0.5% (SFP threshold)
• Late-shipment rate > 4% (SFP secondary metric)

Per-ASIN SFP performance

• Any ASIN-level OTD < 99% rolling 30D (Prime badge at risk for that ASIN)
• ASIN-level cancellation > 1%
• Top-revenue ASINs SFP-eligibility status (priority focus)

Exceptions, claims & failed pickups

• Exception rate > 3% rolling 30D
• Open claims unresolved > 14 days (Amazon A-to-z claim window)
• Wrong-address rate > 1% (data-quality signal)
• Refused-parcel rate > 1%

Cost & service-mix economics

• Avg cost / shipment up >10% vs prior period
• SFP cost per order vs FBA equivalent (when both used) -> economic case
• Same-day / scheduled-delivery uplift > 50% over 2-day
• Claim value as % of SFP revenue > 2% rolling 90D

Cross-platform: revenue at risk (the kill-shot area)

• Cross-platform: ASINs at SFP eligibility risk -> Buy Box loss exposure (amazon.listing.revenue)
• Cross-platform: late SFP shipments triggering Buy Box flips on those ASINs
• Cross-platform: A-to-z claims with no Jira tracker_item -> CS coverage gap
• Cross-platform: SFP-to-FBA migration candidates (ASINs with chronic SFP OTD < 99%)
• Cross-platform: late-delivery refund-propensity * sibling.order.total
