15	Do you have thousands of SKUs with high order variability?	4-Way Shuttle (priority)

Section 3: Vendor Evaluation (10 Questions)

Ask these of every vendor you consider.

#	Question	What a Good Answer Sounds Like

Quick Decision Guide: Which System Is Right for You?

Your Primary Need	Recommended System	Why
Store more pallets in existing space	Pallet Shuttle	60-100% density increase
Reduce cold storage energy costs	Pallet Shuttle (cold-rated)	70-90% fewer door openings
Speed up case/individual item picking	4-Way Shuttle	Goods-to-person, 2-3x faster
Eliminate picking errors	4-Way Shuttle	>99.99% accuracy
Raw materials for manufacturing	Pallet Shuttle	Dense, FIFO, reliable
E-commerce order fulfillment	4-Way Shuttle	Handles SKU chaos and spikes
Both bulk storage AND fast picking	Both (Pallet + 4WS)	One feeds the other
Low ceiling (<8m)	Pallet Shuttle or 4WS (not ASRS)	ASRS needs height
High ceiling (>12m) with pallets	ASRS	Best use of vertical space

Red Flags to Watch For

Vendor Says...	What It Might Mean
"Our system works for everyone."	No deep industry expertise
"You don't need references."	Hiding something
"We'll figure out integration later."	Poor planning
"We guarantee 99.9% uptime."	Ask for proof from real customers
"We can do it in 6 weeks."	Unrealistic timeline

Green Flags to Look For

Vendor Does...	Why It's Good
Asks more questions than they answer	They want to understand your problem
Provides specific industry references	They've done this before
Offers a phased implementation plan	They respect your need for continuity
Has in-house software development	Better integration, faster fixes
Talks about total cost, not just price	They're thinking long-term
