Viable Shipping assembles, packs, and ships your kits from one climate-controlled warehouse near St. Louis, MO, with the same team on every run. For a growing brand, that means dependable kitting services without an in-house assembly team to manage.
Meet Growing Demand without the Overtime, with our 3PL Kitting Team
A well-made kit does quiet work for your store, arriving complete, on time, and looking the part. We handle kitting for ecommerce and DTC sellers who would rather not run that line in-house.
From a small promo to a full launch, nothing about the line changes but the volume.
Custom Kitting Services for Faster Launches
You design it, and every component stays counted in our WMS, so a long run never drifts out of spec.
Our custom kitting services put assembly and shipping under one roof, so a kit is ready to sell the day it is finished rather than sitting between two vendors.
What our Kitting and Assembly Services Cover
Loose components do not sell themselves. Our kitting and assembly services handle the finishing work that turns parts into a retail-ready unit, from a simple two-item bundle to a multi-part build.
Pick the pieces you need:
Custom and Branded Kits
Product selection, inserts, and packaging assembled to your design.
Bundles, Multipacks, and Gift Sets
Subscription & promo boxes included, each barcoded as its own SKU to sell and scan as one unit.
Component and Hand Assembly
Light assembly and multi-part builds done by hand where a machine cannot.
Labeling and Repacking
Product labeling, relabeling, and repacks, including machine-applied bottle labeling for supplements and beauty.
A kit is your brand in your customer’s hands.
Kitting and Fulfillment Services from Assembly to Dispatch
A kit is only useful once it ships.
Our fulfillment kitting services keep finished units on the same shelves our pick and pack team works from, so kits move straight into DTC, wholesale, or Amazon orders without a transfer between buildings.
Finished kits across several channels draw from one stock pool, so you are not splitting kitted inventory three ways.
Our 3PL solutions also offer warehousing for loose components between assembly runs. For Amazon orders, we add FNSKU labeling through our FBA prep service.

Supplements, Beauty & Specialty Goods Covered by our 3PL Kitting Services
Many of the products we kit are sensitive to heat and humidity. Our kitting lines handle supplements, beauty, essential oils, pet products, and other delicate goods, alongside odd-shaped items other kitting companies turn down.
30,000 sq ft
A warehouse built by the team who runs it, with room for your parts and finished kits side by side.
FDA-Registered
We track lot numbers and expiration dates, helping you manage supplement batches and remaining shelf life.
Climate Controlled
Steady temperature and humidity across the whole floor, so nothing melts, clumps, or degrades before it ships.
Our team keeps that stock sellable through the whole build, so each kit leaves looking the way the brand intended.

FAQs about Fulfillment Kitting
Most kits ship within 24 hours of the order once the build is set up. A new kit design or a large launch starts with a short run, so we lock the steps and the count before full volume.
Yes. Our facility is in Leadington, Missouri, about an hour south of St. Louis, so kitting runs from a central spot with fast, low-cost shipping to both coasts.
The kitting companies worth shortlisting build and ship from the same place, track components accurately, hold no order minimums, and can prove accuracy on a real run. Ask to tour the floor or start with a small batch.
Yes. We assemble the kit, apply FNSKU labels and polybags to Amazon’s requirements, and send it in, so your kitted SKUs reach FBA without a second vendor.
Kitting gathers separate products into one ready-to-ship unit, such as a bundle or gift set. Assembly joins or builds parts into a finished product before it is kitted. We do both in-house, so a build and its packout happen in the same place.
Kitting in fulfillment is the process of bundling separate items into a single unit (a “kit”) that receives its own unique SKU. Instead of picking and packing items individually when an order is placed, workers pre-assemble these items ahead of time. This streamlines the fulfillment process, reduces shipping mistakes, and helps e-commerce businesses fulfill multi-item orders much faster.
A kitting service follows a streamlined fulfillment loop:
- Inventory Receiving: Separate individual components are sent to the warehouse.
- Assembly: Workers gather the items, group them together, and place them into custom packaging.
- SKU Assignment: The finished bundle is given a single new SKU.
- Storage & Shipping: Kits are stored together, ready to be quickly shipped as one unit when ordered.
