We just saw a 28% week-over-week lift on crochet bags after a Sunday TikTok, and by Wednesday two DCs were drained while other regions sat at 7+ WOS. For those running tight OTB, what guardrails or transfer triggers are you using to feed the spike without ending up with 10 weeks of tail inventory once it normalizes?
We run a simple “2/5/20” trigger: if any DC drops <2 WOS and another sits >5, auto-transfer up to 20% of source on‑hand, timeboxed to 10 days, then let it decay. We also keep a 3–5% vendor hype hold and only release if 72‑hr conversion stays >X% — it’s a sneeze guard for TikTok spikes, but can starve low-volume regions if you don’t cap per market. Do you have ship‑from‑store live to skip some DC‑to‑DC hops?
