Campaign traffic can multiply daily orders within hours. The sellers who weather spikes well usually prepare three weeks ahead—not three hours.
Start with realistic inbound dates so fast movers are on shelf before ads run. Review pick-station capacity and add temporary labor or shifts if needed. Confirm carrier pickup schedules for heavier parcel days and communicate a clear cut-off time to your warehouse team.
After the campaign, analyze which SKUs depleted faster than forecast and which packaging steps created bottlenecks. That feedback loop makes the next launch smoother.
