A digitally native costume brand transforms hyper-seasonal inventory economics by eliminating months of unnecessary FBA storage through precision-flighted deliveries.
For a digitally native costume brand generating $10M annually, success came with a painful paradox that was crushing their margins.
With 90% of annual revenue concentrated in September-October—and 80% in October alone—they faced an impossible inventory equation. The traditional approach of landing all inventory in mid-July was designed to ensure inventory was fully received and Prime-eligible before the demand surge. But this meant paying FBA storage fees for three and a half months before peak sales even began.
The situation worsened dramatically on October 15th when Amazon's storage fees jumped from $0.43 to $1.43 per cubic foot—right when they still held significant inventory for late-October demand. The math was brutal:
The most frustrating aspect: this was a successful, growing brand with strong demand and healthy unit economics. But the seasonal concentration meant they were essentially paying Amazon to warehouse their success.
"These economics aren't sustainable. We're burning cash on storage while our competitors with inferior products maintain better margins. We need to find opportunities to lower the cost to serve the Amazon channel."
