Kitting, Explained
What Is Warehouse Kitting?
Warehouse kitting combines multiple items into one SKU that is picked, packed and sold as a single unit under one barcode.
Volume Bundles
Group identical units into one SKU, such as a six-pack of a single candle, so a quantity discount does not need a new purchase order.
Curated Gift Sets
Combine different products into a themed box for holidays, welcome kits or influencer seeding, assembled to a layout you approve first.
Virtual Bundles
Sell a set as one listing while the items stay in separate bins and get picked per order. Nothing is pre-assembled, so no stock is stranded in an unsold kit.
Mystery Boxes
Rotate an assortment into a sealed box each month. It is a common way to clear slow-moving stock without discounting your core line.
Assembly Built to Your Spec
What Assembly Work Can a 3PL Do?
Custom Packaging
Pack products into branded boxes in standard shipping sizes, then add tissue, ribbon or a belly band for the unboxing.
Inserts and Samples
Add flyers, thank-you cards, samples or a QR-coded offer to every order, or only to orders from one sales channel.
Rework and Relabeling
Relabel, re-barcode or repackage damaged retail cartons, and swap a faulty component so the unit ships instead of being written off.
Protective Packing
Add foam inserts, dividers or double-wall cartons for glass and fragile items before the kit joins the pick line. See how we ship glass bottles.
Why Brands Choose IWS for Kitting
Same Team, Written Spec
The same crew builds each run from a written spec sheet with photos, so the five-thousandth kit matches the first one.
Small Runs to Pallet Programs
We run one-off promotional builds and recurring monthly programs, from a few hundred kits up to full pallet runs for retail accounts.
99.98% Order Accuracy
Every component is scanned as it enters the kit. That scan discipline is how IWS holds 99.98% order accuracy across outbound orders.
Quoted Per Project
Kitting is quoted per project on components, build time and packaging, with no onboarding fee. Special services fees explains how 3PLs bill this work.
