Amazon Kitting and Bundling Service for Established Sellers and Brands

Marketplace Prep assembles multi-packs, virtual bundles, and subscription kits for sellers moving real volume. We build each kit to your exact spec, label it as a single FNSKU, and execute the FBA shipment plan our software pulls from Seller Central.

What kitting and bundling actually controls

Amazon treats the assembled bundle as the product of record, not its components. The quantity per pack and the label on the outer unit have to be right the first time.

Kitting and bundling is the physical assembly of two or more units into one sellable item that moves under a single FNSKU. For Amazon sellers, that covers multi-packs of the same SKU, mixed bundles of complementary products, promotional sets with an insert, and subscription-style assemblies. The bundle ships and sells as one unit, so it has to be built, labeled, and counted as one unit before it ever reaches a fulfillment center. A bundle built to the wrong component count, sealed with a mismatched FNSKU, or packed against the wrong case-pack quantity gets flagged at the fulfillment center, and the correction loop runs through Seller Support while your inventory sits unsellable.

Marketplace Prep handles kitting and bundling under both service lines. For FBA-bound bundles, assembly and FNSKU labeling run through our software, which pulls the FNSKU and the shipment plan straight from Seller Central, so the bundle is built, labeled, and reconciled against the inbound plan in one operation. For direct-to-consumer bundles and subscription boxes, virtual kits are configured in ShipHero so the assembled unit decrements its component inventory correctly on every order.

How we handle it

Bundle work runs across two channels here, so these are parallel controls rather than one line. Each of them holds the component count and the label together.

Built to your documented spec

Before a single unit is assembled, we document the bundle spec: component SKUs, quantity per bundle, insert placement, and packaging. That spec lives in your client record and drives every build, so the bundle you scoped is the bundle that ships.

Single-FNSKU labeling by our software

Each assembled FBA bundle is labeled as one unit under its own FNSKU, which our software pulls straight from Seller Central. The same system reconciles the labeled bundles against the FBA shipment plan, so component counts and unit counts match what Amazon expects on the inbound.

Inspection at the component and bundle level

We inspect components on receipt and check the finished bundle before it is sealed. Quantity per pack, component match, and insert placement get verified, because a bundle built wrong is far costlier to unwind than to catch on the floor.

Virtual kits for DTC and subscription boxes

For direct-to-consumer bundles, we configure virtual kits in ShipHero. The kit is sold as one item while inventory decrements at the component level, which keeps your stock counts honest across channels.

Case-pack and compliance alignment

Bundles are built and boxed to Amazon case-pack requirements so the inbound plan is compliant. We align the outer-box quantity to your shipment plan rather than packing to a generic default.

Who this is built for

If you sell multi-packs or value sets, your margin lives or dies on whether every bundle ships with the right component count under the right FNSKU.

A fit

Private label brands running promotional sets, insert-driven packaging, or gift assemblies without holding bundle inventory upstream.
Wholesale sellers converting single-unit receipts into Amazon-ready multi-packs that match case-pack requirements.
Direct-to-consumer brands running subscription boxes or curated bundles, where a single sold item has to draw down the correct components.
Established sellers shipping 3,000 units a month or more who have moved past assembling bundles by hand.

Not a fit

Volume under 500 units a month. The reconciliation work costs more than it saves at that size.
Anyone shopping on rate alone. We price for the complexity of the bundle, not a race to the bottom.
Anyone looking for a blanket promise before the spec is defined.

Questions we get

What is an Amazon kitting and bundling service?

An Amazon kitting and bundling service assembles two or more units into one sellable bundle that moves under a single FNSKU. Marketplace Prep builds each bundle to your documented spec, labels the assembled unit, and executes the FBA shipment plan our software pulls from Seller Central, so the bundle reaches the fulfillment center as one compliant unit.

Does an Amazon bundle need its own FNSKU?

Yes. A bundle is treated by Amazon as a distinct product, so the assembled unit carries its own FNSKU rather than the FNSKUs of its components. We label each finished bundle as a single unit under its bundle FNSKU, which our software pulls from Seller Central, and reconcile it against the inbound shipment plan.

What happens if a bundle is kitted or labeled incorrectly?

A bundle built to the wrong component count or sealed with a mismatched FNSKU can be flagged at the fulfillment center, and the correction runs through Seller Support while the inventory sits unsellable. We inspect components on receipt and verify quantity per pack and FNSKU before each bundle is sealed to keep that loop from starting.

Can Marketplace Prep handle bundles for private label and wholesale sellers?

Yes. Private label brands use kitting for promotional sets, insert-driven packaging, and gift assemblies, and wholesale sellers use it to convert single-unit receipts into Amazon-ready multi-packs that match case-pack requirements. Both run through our FBA prep workflow, with labels our software pulls from Seller Central.

Do you handle bundles for direct-to-consumer and subscription boxes?

Yes. For direct-to-consumer bundles and subscription boxes, we configure virtual kits in ShipHero so the kit sells as one item while inventory decrements at the component level. This keeps stock counts accurate across channels.

What volume do I need to qualify for kitting and bundling?

We are built for sellers shipping 3,000 or more units per month, with a hard floor of 500 units per month. We work with private label, wholesale, and brand-exclusive sourcing, and high SKU fragmentation may be scoped at a premium.

How is kitting and bundling priced?

Kitting and bundling sit outside the published per-unit prep tiers on our prep pricing page, so they are quoted per project. Bundle component count, insert handling, and packaging all affect the work involved, so we quote after the spec is defined on a call.

Need kitting and bundling? Let’s scope it.

We do not make blanket promises. We scope every engagement. Tell us your component SKUs, quantity per bundle, and monthly volume, and we will build a plan that fits the actual work.
