What is Cartonization Software? A 2025 Guide for 3PLs and Brands

Cartonization software is a warehouse optimization tool that determines the best box size, weight distribution, and packing sequence for each order. By using cartonization, 3PLs and brands can cut shipping costs, reduce waste, and pack faster without guesswork.

What is Cartonization?

Q: What does cartonization mean in logistics?

Cartonization is the process of calculating the right box or carton for each order based on product dimensions, weight, and shipping rules.

Q: Why is cartonization important?

Cartonization matters because it prevents overpacking, lowers shipping fees, reduces damaged goods, and saves labor time in the warehouse.

How Cartonization Software Works

Here’s how cartonization software like Perseuss fits into the order fulfillment process:

1. The system receives order details (SKUs, product dimensions, weights).

2. Algorithms simulate packing combinations (Business Constraints) and check carrier rules.

3. The software selects the most cost-effective and protective carton.

4. Packing instructions are sent to warehouse staff or the WMS.
   

This ensures every shipment leaves the warehouse optimized for cost and efficiency.

Warehouse packers using Perseuss cartonization software to select the right box size, reducing shipping costs and eliminating wasted space.

Key Benefits for 3PLs and Brands
