Kitting & Bundling

Built for subscription boxes, bundles, and beyond

Cart.com's kitting and bundling service turns individual products into ready-to-ship sets — subscription boxes, gift bundles, promotional kits, retail-ready assortments — assembled inside our fulfillment network, with no separate vendor and no added handoff between assembly and shipment.

Talk to Sales

Every type of kitting, under one roof

From monthly subscription boxes to retail floor-ready display units, Cart.com handles the full range of kitting and bundling programs your brand needs to grow.

Subscription Box Assembly

Cart.com assembles your subscription boxes to spec every month, right components, right order, right on time, whether you ship 500 boxes or 500,000.

Gift Set Kitting

We assemble gift kits with custom tissue, ribbon, inserts, and branded packaging that make unboxing worth sharing, ramping capacity ahead of holidays so your sets are ready when demand peaks.

Promotional Bundle Creation

Cart.com turns individual SKUs into ready-to-ship promotional units fast, assembling, labeling, and staging kits for launches, influencer seeding, and time-sensitive sales events.

Retail-Ready Kits

We build retail kits to your retailer's exact specs, UPC labeling, hanging tags, polybag requirements, master carton configuration, the same standards we've met for major national retailers.

The details that make the difference

Great kitting isn't just about putting products in a box — it's about consistency, accuracy, and the kind of presentation that builds brand loyalty.

Custom Packaging Options

Cart.com supports branded boxes, mailer bags, tissue wrap, ribbons, and custom inserts, working from your brand guidelines whether you supply the packaging or need sourcing support.

Inventory Component Tracking

Each component SKU is tracked individually in our WMS, with automated low-stock alerts so you always know how many complete kits you can fulfill.

Work Instructions and QC

Every kitting program runs from a documented work instruction with QC checkpoints built into the workflow, not bolted on at the end, protecting your brand and your reviews.

Peak Season Scalability

Cart.com plans surge capacity alongside you ahead of Q4, Valentine's Day, and Mother's Day, so assembly throughput doesn't collapse under holiday pressure.

Virtual Kitting Capability

Our OMS supports virtual kitting, where bundle SKUs are defined in software and assembled at pick, ideal for testing new bundle ideas without committing to a full build.

Multi-Channel Bundle Fulfillment

Cart.com handles channel-specific kitting, labeling, and compliance from a single facility, so your inventory doesn't need to live in three places to serve three channels.

Kitting backed by technology, accuracy, and scale

Cart.com's kitting operation is powered by a proprietary WMS that gives you real-time visibility into every component, every kit in progress, and every completed unit ready to ship. Our assembly teams work from digitized work instructions with mandatory scan-verify steps, so substitutions and mis-kits don't make it into your customer's box. As your brand grows — more SKUs, more bundles, more channels — our infrastructure grows with you, scaling throughput without sacrificing the accuracy your customers expect. This is what tech-enabled 3PL kitting looks like.

How Cart.com kitting works

A simple four-step process that takes your products from inbound receipt to a perfectly assembled kit, ready for your customers.

Step 1: Receive

Component inventory arrives, is inspected, and slotted within our WMS, with each SKU tracked from the dock so discrepancies get caught before they become kitting problems.

Step 2: Kit

Trained assembly teams work from your approved instructions, scanning components at the station to verify every unit gets the right items, custom inserts and packaging included.

Step 3: QC

Completed kits go through weight verification, visual inspection, and final scan confirmation before staging. Anything that doesn't pass gets flagged and rebuilt, never shipped.

Step 4: Ship

Finished kits enter the outbound flow like any other SKU, picked, packed, labeled, and shipped through our carrier network, on time and exactly as expected.

Subscription Box Kitting

Subscription boxes live and die by consistency — your subscribers expect the same quality experience, box after box, month after month. Cart.com executes recurring kitting runs on the schedule your program demands, with full component-level inventory tracking to prevent stockouts from derailing a cohort. We support multi-SKU coordination, custom unboxing packaging, and personalized inserts at scale. Whether you're shipping 1,000 or 100,000 boxes per cycle, your subscriber experience stays sharp.

Promotional and Seasonal Bundles

Limited-time bundles are a proven lever for AOV lift and customer acquisition — but only if they ship on time and arrive intact.

Our team can turn a new bundle configuration around quickly when a campaign calls for it. When your seasonal window is short, speed and accuracy aren't optional.

Retail and B2B Kitting

Retail-ready kits have to meet your buyer's compliance standards — wrong labeling or packaging configuration means chargebacks and lost shelf placement. Cart.com builds kits to retailer spec, including UPC placement, inner pack configuration, master carton labeling, and EDI compliance documentation. We've executed retail kitting programs for national chains and independent buyers alike. Your kits arrive compliant, shelf-ready, and on-time.
