Extra stock needs somewhere to move as well as somewhere to sit. A warehouse may have spare shelf space while its receiving bay, picking routes and dispatch bench are already stretched. Before a larger summer order arrives, test the capacity of the whole journey through the building.
Late 2026 planning should account for seasonal peaks and the busiest part of the day. That matters because congestion is usually an hourly problem before it becomes a monthly one.
Start with the choke points
Owners often respond to summer demand by finding room for extra inventory. A better first move is to identify where flow breaks down. The receiving area is a common culprit: goods come in, get checked, wait for space, then spill into aisles that picking teams need. If the same patch of floor is doing three jobs at once, every extra pallet cuts productivity.
Watch one busy shift with a notebook. Note where forklifts pause, where pickers double back, where cartons are left temporarily, and which SKUs trigger repeated crossings of the same aisle. You are looking for friction between receiving and picking, not a perfect diagram. A warehouse can seem full enough on paper yet still have poor use of space because fast movers are trapped behind slow stock or inbound goods are staged too far from put-away locations.
Suppose two additional pallet rows let you hold an extra fortnight of stock. If those rows force staff to take longer picking paths during the busiest two hours, the gain in inventory cover may be offset by slower dispatch, more handling, and a floor that stays cluttered deeper into the day. That trade-off is worth measuring before the purchase order goes out.
Ask the floor, then change the layout
Frontline feedback matters here because staff see recurring snags long before weekly reports do. Ask where they regularly wait, which products create queueing, and what gets shifted twice. The useful answers are usually small and specific: move one promotional line closer to dispatch, mark a temporary holding zone for inward goods, change the delivery window for one supplier, or shift returns away from the main pick face.
Any changes to vehicle and pedestrian routes need an appropriate safety review. Separation helps. If you can give receiving a defined staging area and protect pick paths from overflow, the warehouse becomes easier to read and easier to schedule. If space is tight, create time separation instead: receive slower lines earlier, hold replenishment until after the first pick wave, or tighten cut-off times so the floor is not trying to absorb everything at once.
Extra stock has a cost beyond the invoice. It can hide layout weakness, absorb labour into unnecessary movement, and make service less predictable when summer orders lift. Clearing the path first gives you a better basis for deciding what stock depth the building can genuinely support.
