What is kitting in a warehouse?

Kitting is assembling separate items into one ready-to-ship kit before orders arrive. The warehouse picks the components, packs them together, labels the kit with its own SKU and stores it as a finished product. When an order comes in, the kit is picked as one unit. Gift sets, combo packs and trial kits are typical kitted products.

What is the difference between kitting, bundling and assembly?

Kitting usually means building a kit in advance from finished items, so kits sit on the shelf with their own label. Bundling is the broader marketing term for selling items together, either pre-built or put together at order time as a virtual bundle. Assembly, in manufacturing, joins parts into a new product; manufacturing kitting gathers those parts for the assembly line.

How does kitting work in ecommerce, with an example?

A skincare brand sells a festive kit of a face wash, a serum and a cream. Before the sale, the warehouse picks 200 of each, assembles 200 boxed kits, labels them with the kit's own barcode and puts them away in one bin. Each kit order is then a single pick. After the festival, unsold kits can be broken down into components again.

What happens to inventory when a kit or bundle is sold?

With a pre-built kit, stock of the components drops when the kit is built, and the kit's own stock drops when it sells. With a virtual bundle, nothing changes until an order arrives; then each component's stock drops by its quantity in the kit. Either way, the components' stock across channels must reflect what is left.

When should a brand pre-build kits instead of picking them at order time?

Pre-build when demand is high and steady, such as a festive gift set, when the kit needs special packaging, or when picking three items for every order would slow dispatch. Pick at order time when demand is uncertain or the components sell well on their own. Many brands pre-build part of the expected volume and leave the rest virtual.

Can you break a kit back into its components?

Yes. This is called disassembly or de-kitting. Unsold kits are opened, the components are checked and put back into loose stock, and the kit stock is reduced. It costs labour and sometimes packaging, so build festive kits in stages. Record batches and expiry dates on the components, so they go back into the right stock.

Do combo packs need their own label and MRP in India?

Yes, if the combo is sold as a retail package. The Legal Metrology (Packaged Commodities) Rules, 2011 require each retail package to carry its retail sale price, and a package with more than one product must state the name and number or quantity of each one. Packages grouped together on a promotional offer must each comply with the same declarations.

What are the benefits of kitting for an ecommerce warehouse?

Pre-built kits turn several picks into one, which speeds up dispatch on busy days such as festive sales. Each kit is assembled and checked once at a packing table, not under order pressure. Kits also let a brand sell gift sets and combos as one product. The costs are the labour to build them and stock locked into kits until they sell.

What is kitting?

Kitting is the warehouse process of gathering separate items and packing them together as one ready-to-ship unit, called a kit, which is sold under its own SKU. Gift sets, combo packs, trial kits and subscription boxes are common examples. When a kit is built, the component items leave loose stock and the kit's stock goes up.

In manufacturing, kitting has a second meaning: gathering the parts for one assembly job and sending them to the production line together. This page is about kitting for orders.

How kitting works in an Indian D2C or omnichannel warehouse

Kitting, bundling and virtual bundles

	Pre-built kit (kitting)	Virtual bundle	Bundling (general use)
When it is put together	In advance, before orders arrive	At order time, from loose stock	Either; the word covers both
What sits on the shelf	Finished kits with their own label	Only the loose components	Depends on the method
SKUs	One kit SKU, built from component SKUs	One listing, made of component SKUs	One listing
Best for	Festive gift sets, high volumes, kits in special packaging	Combos with uncertain demand, “buy 2” offers	Marketing term for any combined offer

The kitting process

Kit work order. Decide how many kits to build and from which components.
Pick the components from their bin locations using a pick list.
Assemble the kit at a packing table, with any insert, sleeve or gift box.
Label the kit with its own barcode and the declarations a retail package needs.
Put the kits away in their own bin, so they are counted separately.
Sell and ship the kit like any other SKU through pick and pack.

Disassembly (de-kitting). After a festival, unsold kits can be broken back into components and returned to loose stock, so a face wash in an unsold gift box can sell on its own again.

Example: a “Festive Glow Kit”. A skincare brand sells a kit of one face wash, one serum and one cream. It starts with 500 of each component in loose stock and receives 50 kit orders. All numbers are illustrative.

	Pre-built: 200 kits built in advance	Virtual bundle: nothing built in advance
Loose stock after building	300 of each component	500 of each component
Kits on the shelf	200	0 (assembled at order time)
After 50 kit orders: loose stock	300 of each	450 of each
After 50 kit orders: kits available	150 built kits	Up to 450, limited by the scarcest component

Pre-building is faster to pick on busy days, but locks 150 units of each component into kits that can’t be sold separately. A virtual bundle keeps stock flexible, but every kit order is three picks instead of one.

Common mistakes

Listing a kit without reserving its components. If the face wash also sells on its own, a virtual bundle can be promised and then fail at picking.
Forgetting the kit’s own label and price. A combo pack is a retail package and needs its own declarations.
Building too many kits before a sale. Leftover kits either take labour to break down or turn into dead stock.
Not counting kits separately. Kits stored in the same bin as loose components confuse every stock count.
Mixing batches with different expiry dates in one kit without recording them, which makes a recall or expiry check slow.

Kits built per hour = kits assembled ÷ labour hours. Example: 240 kits in 8 hours is 30 kits an hour.
Kit sell-through = kits sold ÷ kits built. Example: 170 of 200 is 85%; the other 30 need a plan after the season.
Component availability = the lowest component stock ÷ units of that component per kit. Example: 450 ÷ 1 = 450 kits.

Kitting in the Indian context

Combo-pack labels. Under the Legal Metrology (Packaged Commodities) Rules, 2011, a package with more than one product must state the name and the number or quantity of each product (rule 6(1)(b)), and every retail package carries its retail sale price (rule 6(1)(e)). The rules also say that when packages meant for retail sale are grouped together and sold as one retail package on a promotional offer, every package in the group must comply with rule 6.
Food kits. Food labels also follow the FSS (Labelling and Display) Regulations, 2020, which require a batch, code or lot number and expiry or use-by dates (regulations 5(9) and 5(10)). Record them for each component that goes into a snack hamper.
Festive demand. Diwali and Rakhi gift sets sell in a short window, so pre-built kits suit them; build in stages instead of all at once.

How Fretron CommerceOS handles kits and bundles

In Fretron CommerceOS, a bundle sold on an order is split into its component items, and kits can be assembled and taken apart in the warehouse module.
