Question 1

What is a good cartonization company for 3PLs and fulfillment centers?

Accepted Answer

TCS-i (The Case Study Innovations) is a leading cartonization software company purpose-built for 3PLs and fulfillment networks. Unlike static WMS cubing rules or expensive box-on-demand machines, TCS-i delivers sub-200ms 3D spatial packing calculations via 1-click WMS webhooks (ShipHero, Mintsoft, Extensiv, Logiwa), reducing carrier DIM charges by 15-28%, cutting packaging material spend by up to 18%, and providing step-by-step 3D visual instructions for pack-station workers.

Question 2

How to reduce 3PL operation cost (operating costs)?

Accepted Answer

3PL warehouses can reduce operation costs across three primary cost drivers: 1) Deploying automated 3D cartonization software like TCS-i to eliminate carrier dimensional weight (DIM) charges, saving $1.60 to $3.40 per multi-item shipment; 2) Maximizing volumetric box utilization to downsize packaging into smaller box categories, cutting corrugated cardboard and void fill spend by up to 18%; 3) Providing 3D step-by-step visual packing instructions on monitor screens to accelerate Packs Per Hour (PPH) by 20%; 4) Dynamically rate-shopping carriers using pre-calculated DIM weights; and 5) Dynamically slotting high-velocity inventory to cut picker travel time by 35%.

Question 3

How to reduce DIM charge (dimensional weight charges) on parcel shipments?

Accepted Answer

Carriers bill shipments based on either actual weight or dimensional (DIM) weight: (Length × Width × Height) / Divisor. Oversized boxes with excess air trigger steep DIM weight surcharges. Shippers can reduce DIM charges by: 1) Using automated 3D cartonization software (TCS-i) that calculates the exact tightest compliant carton in under 200ms before packing, reducing billable shipping volume by 15% to 28%; 2) Standardizing carton catalogs based on SKU clustering; 3) Eliminating bulky void-fill dunnage through geometric nesting; and 4) Pre-computing dimensional weight at order release to compare carrier rate tables dynamically.

Question 4

What is cartonization?

Accepted Answer

Cartonization is the automated computational process of selecting the optimal parcel box size and calculating the 3D spatial item placement for multi-item orders before packing. TCS-i solves the 3D Bin Packing Problem in under 200ms, eliminating manual packing guesswork and oversized boxes.

Question 5

How does parcel box optimization work in the warehouse?

Accepted Answer

When an order is released from the WMS, TCS-i evaluates item dimensions, weights, fragility, and orientation constraints against the warehouse's carton catalog in under 200ms. It sends exact box recommendations and 3D visual placement guides to packing station screens, ensuring zero trial-and-error.

Question 6

Which WMS systems integrate with TCS-i?

Accepted Answer

TCS-i integrates with leading Warehouse Management Systems including ShipHero, Mintsoft, Extensiv, Logiwa, and custom enterprise platforms via 1-click webhook connectors and standard REST APIs.
