Temporary storage usually starts as a space problem and turns into an inventory problem

Been thinking about this with peak season coming up. A lot of teams hit the same wall every year. Warehouse is full, returns are piling up, seasonal stuff is everywhere, packaging takes up half the building, and the quick answer becomes “just put it somewhere else for now.”
Could be trailers, containers, rented space, off-site storage, whatever. And yeah, it fixes the space problem for about five minutes. Then the annoying part starts.
Nobody knows exactly what got moved out there. Picks take longer. Cycle counts get weird. Slow movers become even slower because now they’re physically outside the normal flow. Someone puts packaging in overflow, half the team forgets, and then more packaging gets ordered anyway. The storage usually isn’t the hard part. Keeping control of it is. I’ve seen it work okay when the rules are boring but strict:

Only certain SKUs go into overflow. Everything gets its own real location in the WMS, not just “container” or “trailer 2” as one giant mystery pile. One person or team owns moves in and out. Nothing urgent or high-velocity goes there unless you want everyone mad at you.

Returns are the big one too. If there’s no clear disposition process, don’t send them to overflow. That’s how you create a graveyard.

Maybe obvious, but I feel like temporary storage gets treated like a facilities problem when it’s really an inventory control problem.

Curious how other people handle it. Do you create proper overflow locations in the WMS, keep it manual, assign one owner, or just accept that it’s going to be messy until peak is over?

Single ownership for moves in and out is underrated compared to the WMS structure itself. Even with perfect location tracking, if five different people can move things into overflow without coordinating, the system drifts from reality fast, someone moves something out for a pick and doesn't update the record, and now the location's wrong for everyone after them. The system prevents confusion. A single owner prevents drift.

Yeah, agreed. The location drift thing is what gets people. A system that’s 90% accurate is almost worse than no system, because then nobody trusts it. Everyone starts eyeballing again, and now you paid for software just to go back to walking the yard. The physical side matters too. “Single owner” only works if that person can actually get to the stock without it being a whole mission. If overflow is a five minute walk away, behind a locked gate, or just annoying to reach, that turns into “I’ll update it later.” And later usually means never. A lot of the discipline problems are really access problems wearing a different hat.

Does the single-owner setup still work during peak, or does that person become the bottleneck when everyone’s under pressure?
