What is warehouse assembly kitting or kitting fulfillment?

Warehouse assembly kitting, also known as kitting fulfillment, is the process of assembling, grouping, and packaging multiple products into a single kit with one SKU so it can be stored, tracked, and shipped as one unit.

Why should I use a 3PL for assembly and kitting services?

Using a 3PL for assembly and kitting services reduces labor and packaging costs, improves accuracy, and allows businesses to scale without investing in additional warehouse space, staff, or systems.

Do you handle custom bundles, gift sets, and promotional kits?

Yes. Our assembly kitting services include custom bundles, gift sets, promotional kits, influencer kits, and event kits with custom packaging, inserts, QR codes, and special instructions.

Is kitting fulfillment only for ecommerce businesses?

No. Kitting fulfillment is used by ecommerce brands, B2B distributors, retailers, subscription box companies, and businesses shipping multi-item orders or promotional bundles.

Can Fulfillment Plus support temperature-sensitive or special handling requirements?

Yes. We provide custom packaging and special handling options, including temperature-sensitive packaging, as part of our assembly and kitting services upon request.

Why Assembly and Kitting Matter

Faster order turnaround & reduced lead times: Because items are pre-assembled into kits, once you get an order, we can ship it out quickly. No need to pick multiple SKUs for each order.
Lower labour and fulfillment costs: Assembly and Kitting reduces repetitive picking and packing tasks, cutting down staff time and reducing labour costs per order.
Improved inventory accuracy & simplified management: By consolidating components into a single kit SKU, inventory tracking becomes easier with fewer SKUs, fewer mistakes, and better forecasting.
Reduced packaging and shipping costs: Bundled products in one package often cost less to ship than multiple individual boxes especially when you use custom packaging tailored to the kit size.
Better warehouse space utilization: Kits stack neatly and reduce clutter freeing up space, improving organization, and allowing you to store more SKUs efficiently.
Enhanced customer experience and increased order value: Kits give customers convenience (everything they need in one box), encourage upsells and bundles, and often lead to higher average order values.
Scalable and flexible operations: As your order volume grows, you don’t need to ramp up complex in-house assembly kitting. Our assembly and kitting services scale smoothly.

How Our Assembly and Kitting Workflow Works

Here’s a detailed breakdown of how we operate when you partner with us for kitting fulfillment services:

Receiving & Inventory Intake

When your components — individual items, accessories, inserts — arrive at our warehouse, we receive and inspect them. Each component is logged into our warehouse management system (WMS), identified by SKU or barcode, and stored safely.

Kit Definition & Setup

Based on your instructions, we define the kit contents in our system: which SKUs go together, quantities, packaging requirements, inserts or custom materials. Each kit is assigned a unique kit-SKU for tracking and kitting fulfillment.

Expertise in FBA/FBM

FBA/FBM support for seamless e-commerce kitting fulfillment. Authorized Amazon Service partner and Shopify Partner.

Returns & Restocking

If returns occur, we process them, inspect the kit or components, restock saleable kits or break them down if needed, and update inventory in real time. This full end-to-end process from component receipt to kit delivery gives you a streamlined, reliable workflow without the hassle of manual assembly kitting or complex operations.

Inventory Organization & Storage

We organize components logically by product type, bundle group, or your custom defined assembly and kitting structure. This clear organization ensures easy retrieval when it’s time to assemble kits.

On-Demand Assembly and Kitting Services

Our on-demand assembly and kitting services allow kits to be assembled only when an order is placed. Individual components are picked, assembled, and packed per order, making this approach ideal for custom bundles, limited-time promotions, and dynamic product combinations. This method reduces excess inventory, increases flexibility, and ensures each kit is built accurately based on real-time demand.

Quality Check & Custom Packaging

After assembly, every kit goes through a quality check to verify completeness and packaging standards. Then we pack the kit using appropriate boxes possibly with branded packaging, custom inserts, QR codes, instructions or promotional material, according to your brand’s guidelines.
