What's included

How kitting actually works at Matrix.

Kitting can mean many things — a 3-piece skincare set, a 12-pack subscription box, a custom influencer mailer, a Costco-style bundle. Here's how we handle each.

Kit specification

You send us the kit recipe — which component SKUs go in, in what quantity, with what packout. We build the kit as its own master SKU in the WMS with a defined Bill of Materials.

Pre-kitting (in advance)

For predictable kits — gift sets, multi-packs, subscription boxes — we assemble in bulk in advance during off-peak hours. Faster pick speed, lower per-order cost, photographed before storage.

On-demand kitting

For custom kits — variable component combinations, personalized inserts, made-to-order influencer mailers — we assemble at pick time. Slower per order, but no waste if demand changes.

Component inventory tracking

Every kit deducts its components from inventory. If a kit uses 3 SKUs, your inventory dashboard shows 3 SKUs going down as kits ship. Component shortages auto-flag before they affect kit availability.

Photo documentation

Every kit configuration is photographed during initial build and stored in your account. Reference for QC, helpful for marketing teams who need product photos, useful in customer service when someone claims their kit was wrong.

Kit-specific packout

Kits often need different packout than standalone products — gift wrap, theme tissue, branded insert cards, magnetic closure boxes. Configurable per kit SKU.

Why Matrix

Why kitting is harder than it looks.

Most 3PLs treat kitting as "add this to the picking workflow." The reality is component tracking, kit-specific packout, photographic QC, and shortage prevention are real operational disciplines that affect every kit you ship.

Bill of Materials tracking in WMS

Every kit SKU has a defined BOM in ShipHero. Component inventory deducts automatically. No manual reconciliation, no "we ran out of an ingredient mid-kit" surprises.

Pre-kit vs on-demand decision logic

Some kits should be pre-built (high volume, stable recipe). Others should be on-demand (variable, custom, low volume). We help you decide which is which based on your actual demand pattern.

Shortage forecasting

Component-level inventory means we can forecast a stockout 30 days out, not just when the kit runs to zero. Reorder lead times matter — you don't want to find out you're out of one ingredient when 500 orders are queued.

QC photography on every recipe

Every kit configuration photographed at first build. Reference for pickers, packers, QC, customer service. Reduces "this isn't what I ordered" complaints by 40-60%.

Kit-specific packout assets

Gift wrap, branded insert cards, theme tissue, magnetic boxes — all stored as kit-specific packout. Standard kit ships in its proper presentation without packer judgment.

Single SKU = simpler operations downstream

Once a kit is built and stored, it picks and ships as a single SKU. No multi-line pick for a 12-component kit at order time — it's one bin, one scan, one pack.

Who it's for

When kitting is the right service.

Beauty brands selling gift sets

Skincare routines, makeup kits, holiday collections. High-volume pre-built kits with branded packout.

Subscription box brands

Monthly theme box assembly. New recipe each month, predictable volume, cohort-aligned shipping cycles.

Influencer and PR programs

Custom one-off kits for influencer seeding. On-demand assembly, photographed for marketing reference, personalized with handwritten notes.

Multi-pack products on Amazon

Bundling individual units into multi-packs for FBA. Often required as FBA prep step before shipment to Amazon.

Retail gift-with-purchase programs

Gifts assembled with main products for specific promotional windows. Conditional assembly logic — only orders meeting criteria get the gift.

Crowdfunding reward tier assembly

Kickstarter and Indiegogo rewards often involve multi-component tiers. Each tier is a distinct kit SKU.

Pricing

Transparent, itemized, no minimums.

Kitting priced per kit assembled. Simple 2-3 component kits run $0.50-$1.00/kit. Complex 5-10 component kits with branded packout run $1.00-$3.00/kit. Subscription box assembly often quoted as a flat per-box rate. Special projects $40/hr.

FAQ
How do you price kitting?
Per kit assembled, based on complexity. Simple 2-3 component bundles are $0.50-$1.00/kit. Complex 5-10 component sets with branded packout, gift wrap, and inserts are $1.00-$3.00/kit. We quote based on your actual kit spec.
Do you handle subscription box assembly?
Yes. Subscription boxes are kitted by cohort — all September boxes built and stored, then released for shipping in a single cohort window. Most subscription brands prefer flat per-box pricing for predictability.
How do you handle component inventory?
Every kit has a Bill of Materials in the WMS. When a kit is built, components deduct from individual SKU inventory. Real-time inventory dashboard shows component-level and kit-level stock.
Can you do custom kits per order?
Yes. On-demand kit assembly handles variable kit configurations — personalized influencer mailers, made-to-order gift sets, custom B2B configurations. On-demand kits cost more per unit than pre-built kits.
What if I run out of one kit component?
Component-level forecasting flags potential shortages 30 days out. If a component runs short, the kit SKU goes out-of-stock until replenishment. We coordinate with you on inbound timing.
Can you photograph kits for marketing?
Yes. Every kit configuration is photographed during initial build for QC reference. Photos can be made available for marketing use, often saving the cost of a separate product photography session.
