What Are 3PL Kitting Services?

What Are 3PL Kitting Services? A Complete Guide for Ecommerce and B2B Brands

Many brands rely on 3PL kitting services to bundle products efficiently and improve fulfillment speed. Whether it’s subscription boxes, promotional kits, or bundled SKUs for retailers, kitting ensures accuracy, consistency, and cost savings across every order.

What Is Kitting in Fulfillment?

Kitting is the process of combining multiple individual products into a single ready-to-ship package. A 3PL (third-party logistics provider) handles this process on behalf of brands, ensuring each kit is pre-assembled, labeled, and stored for quick order turnaround.

For example, a cosmetics company might package a cleanser, toner, and moisturizer together as one SKU — or a supplement brand may bundle vitamins for a 30-day supply kit. Instead of assembling each order individually, 3PL teams pre-kit them in bulk to save time and labor.

Why Businesses Use 3PL Kitting Services

Outsourcing kitting to a 3PL gives brands several key advantages:

Faster Fulfillment: Kits are pre-assembled and ready to ship, reducing warehouse handling time.

Inventory Accuracy: Every component SKU is tracked through the warehouse management system (WMS), preventing shortages or overstocking.

Cost Efficiency: Fewer touches mean lower labor costs and reduced shipping expenses.

Packaging Consistency: Every kit looks identical, protecting brand presentation and customer experience.

Scalability: When order volumes spike during promotions or holidays, your 3PL can quickly scale production.

These efficiencies are especially valuable for ecommerce, subscription boxes, and B2B retail fulfillment.

The Kitting Process Explained

The exact process may vary by 3PL, but generally includes these key steps:

Inventory Receipt and Storage: Components are received, barcoded, and stored in specific warehouse zones.

Bill of Materials (BOM) Setup: Your 3PL defines which SKUs make up each kit.

Assembly and Quality Control: Items are pulled, assembled, and inspected to ensure accuracy.

Labeling and Packaging: Kits are labeled with unique barcodes and stored as single SKUs.

Fulfillment: When orders come in, the pre-kitted item ships like any standard product — fast and error-free.

Many 3PLs use WMS technology to track kitting activity in real time, ensuring complete visibility and inventory control.
