1. Top story of the day
Risk Point: ShipStation is reporting a partially degraded service due to inaccurate cubic rates for USPS mailing services. This affects shipping cost calculations at checkout and fulfillment.
Why it matters: Inaccurate cubic rates lead to undercharging customers for shipping, eroding margins, or overcharging them, increasing cart abandonment. It also causes fulfillment delays as staff manually correct costs.
Who is affected: All Shopify stores using ShipStation for USPS shipments. Shippo, ShipEngine, and AfterShip remain fully operational.
Action timeline: Immediate verification of shipping labels. Monitor ShipStation updates for resolution.
Impact note: If you rely on real-time carrier calculations, this may cause checkout errors or post-purchase refund requests.
