The practical warehouse storage decision guide
A step-by-step worksheet you can use before requesting a rack layout or supplier quote.
Step 1: Define the real problem
Before choosing a product, write down the operational issue. Are you running out of pallet positions? Spending too much time traveling? Struggling with SKU access? Or preparing for growth? Different problems require different solutions.
Step 2: Collect these inputs
- Building length, width, and clear usable height
- Column grid, docks, exits, sprinkler and utility constraints
- Current and forecast pallet counts
- SKU count and product turnover
- Maximum loaded pallet dimensions and weights
- Forklift models, turning requirements, and lifting limits
- Receiving and shipping volume during peak periods
- Inventory rotation requirements (such as FIFO)
Step 3: Identify the trade-off
Imagine two fictional operations:
Operation A: many SKUs
A parts distributor has frequent picks from many different products. Easy pallet access may outweigh maximum storage density. Selective rack is a logical system to evaluate first.
Operation B: bulk inventory
A manufacturer holds large batches of a few products. Higher-density systems may be worth exploring, provided rotation and handling requirements fit.
Step 4: Ask vendors the same questions
- How many usable pallet positions does the proposed layout provide?
- What assumptions were made about load size, weight, and equipment?
- Which pallets will not have direct access, if any?
- What safety, permitting, and fire protection reviews are required?
- What installation disruption and ongoing maintenance should we expect?
- How will the design handle forecast growth or changing inventory?
Step 5: Evaluate the whole operation
Compare proposals on capacity, accessibility, handling effort, safety, flexibility, and total costs—not rack purchase price alone. Ask for a drawing and written design assumptions so your team can verify the proposal.
