What are kitting and assembly services?

Kitting and assembly services are 3PL operations where a fulfillment partner combines individual components or products into finished, ready-to-ship units. Kitting groups multiple SKUs into a single package — like a subscription box or promotional bundle. Assembly involves physically constructing a product or display from components. Most brands outsource kitting and assembly to avoid building a dedicated production operation in-house.

What's the difference between kitting and assembly?

Kitting involves grouping multiple separate items together as a single unit (like a subscription box), while assembly involves physically combining components to create a finished product. Productiv handles both, often in integrated workflows where components are assembled into sub-kits that then merge into a finished sellable unit.

What is the difference between kitting and contract packaging?

Kitting combines existing finished goods into a new package. Contract packaging involves primary or secondary packaging of a product — shrink wrap, retail-ready packaging, display packaging, or co-packing. Productiv handles both, often in the same program: a seasonal retail program might require co-packing individual items before they're kitted into a retail gift set.

When should a brand outsource kitting and assembly?

The right time to outsource kitting and assembly is when your internal team is spending meaningful time on production work that isn't core to your business — or when volume requirements exceed what you can handle without dedicated space and labor. Brands typically outsource when they're hitting 500+ kits per month, launching a subscription program, winning a major retail account, or facing seasonal surges that exceed in-house capacity.

How much does kitting cost per unit?

Kitting is typically priced at $0.04 to $0.08 per item placed, plus a base kit fee of $0.25 to $0.75 per finished kit. The base fee reflects complexity factors including lot and batch control requirements, special labeling or inspection steps, packaging type (box build and seal, heat-sealed bag, or gift box with fill), and required accuracy tolerance. A 10-item mid-complexity kit with standard box build and no lot control might run $0.65 to $1.05 all-in per kit. Regulatory kits with 75+ lot-controlled items run higher due to the documentation and verification steps at each stage.

How long does it take to launch a kitting program?

Launch timeline depends on where finished kits are going after assembly. Programs shipping back to a manufacturing site can start within 24 to 48 hours of components arriving — enough time to receive the BOM, build and approve a First Article, and run the line. DTC programs take about one week to set up order management integrations. B2B retail programs require 6 to 12 weeks because each retailer requires its own EDI connection setup and testing cycle before the first shipment. Productiv is pre-wired for 100+ retailers, which eliminates the mapping work but not the retailer testing cycle.

What does the kitting process look like step by step?

A standard kitting program moves through six stages: (1) Inbound receiving and inspection — components arrive and are verified against the BOM, with at least one carton opened per pallet per SKU to catch vendor concealed shortages; (2) Inventory slotting — components are positioned in the work cell to minimize pick travel and maximize throughput; (3) Pick and kit — operators pull components per BOM and assemble the finished unit, with scan gun verification at each pick; (4) Quality inspection — barcode verification, weight check, and photo documentation confirm accuracy at the unit level; (5) Compliance labeling — retailer-specific labels, UCC-128 case labels, and GS1 barcodes applied per spec; (6) Pack out and post-job reconciliation — finished kits are packed, extras and shorts are documented and reconciled in the system, and the job closes with a complete inventory record.

How do you ensure quality across high-volume kitting?

Productiv uses a multi-step process: components are verified on scan guns at pick, signed off by a supervisor at the production floor handover, independently re-verified by the production team at intake, and reconciled after each job against finished kit counts, extras, shorts, and damages. The most common source of inventory error is vendor concealed shortages — caught at receiving by opening at least one carton per pallet per SKU before production begins. This process maintains inventory accuracy above 99% across programs running 1,000+ SKU movements per day.

What accuracy rates does Productiv achieve for kitting?

Standard kitting accuracy targets are 99.5–99.95%. Regulated and compliance programs (medical devices, financial cards, controlled products) are held to 100% accuracy with full lot/batch documentation. Productiv uses ProQuality, an operator-built AI quality workflow tool, for First Article Inspection and ongoing quality control.

What is ProQuality and how does it improve kitting accuracy?

ProQuality is an operator-built AI workflow tool Productiv uses for First Article Inspection and quality control in kitting programs. When a new kit configuration begins production, ProQuality auto-routes First Article photos to the client for approval before the full run begins. This eliminates the most common source of kitting errors — incorrect configuration approved verbally but not validated against the actual first-built unit.

Can you handle variable or customized kits?

Yes. Productiv supports dynamic kit configurations including monthly configuration changes on subscription programs, multiple finished-good SKU varieties running simultaneously, and lot-controlled regulatory kits where each unit requires specific item placement documentation. Programs with 30 to 50 different finished-good configurations are standard — each gets its own line setup, component staging, scan gun configuration, and quality checkpoints.

Can Productiv handle kitting with lot and batch control requirements?

Yes. Productiv operates clean room environments and lot/batch controlled kitting lines for regulated products including medical devices and regulated consumer goods. Programs with lot control requirements include full documentation per job, and accuracy targets are held to 100%. One program manages 75 regulated items per kit with full lot tracking.

Can kitting be combined with DTC and retail fulfillment from the same inventory?

Yes, but this requires specialized inventory discipline. When the same inventory pool feeds kitting jobs and outbound DTC or B2B orders simultaneously, components are constantly being pulled for kits and returned as finished goods while also being decremented for individual orders. Productiv manages this through supervised handover at each stage, real-time system updates for put-backs and shorts, and post-job reconciliation before the job closes. Programs running 100+ component SKUs through this model maintain inventory accuracy above 99% using this process.

What types of kitting programs does Productiv handle?

Productiv handles subscription box kitting (monthly/seasonal with variable SKUs), retail gift set assembly (seasonal gifting programs for major retailers), industrial kitting (parts staging, manufacturing support), promotional and marketing kits (influencer mailers, event kits, product launches), Amazon FBA prep, POP display assembly, contract packaging, repack and relabel, and drone and robotics component assembly.

How large can kitting programs scale?

Single programs at Productiv run as high as 80,000 kits per day. One beauty brand program runs 20 million kits per year. Productiv can ramp from zero to full production capacity within 24–72 hours for surge programs, and maintains flexible staffing infrastructure to handle peak seasons without compromising other clients.

Does Productiv use temp agency labor for kitting?

No. Productiv operates a W2-only workforce with no temp agencies. Line leads, supervisors, account coordinators, and site managers average 10+ years of tenure. This means consistent quality, institutional knowledge carried forward from program to program, and accountability for outcomes rather than hours.

Does Productiv use robots for kitting?

Yes. Productiv operates 13 cobots, 2 humanoid robots, and 1 palletizing robot in live production at its Dallas facility. Robots handle pick-and-place tasks on kitting lines alongside human operators. As of early 2026, robot pick accuracy has reached 99%+ on validated SKUs, with takt time improved from 12–15 seconds per pick to 6 seconds. Productiv continues to expand robot-assisted kitting as models improve.

Where are Productiv's kitting facilities located?

Productiv operates two kitting locations: Charlotte, NC (two warehouses serving the Mid-Atlantic and Southeast) and the Dallas/DFW metroplex (two warehouses in Grapevine, TX, the highest-volume site, with 13 cobots, 2 humanoids, and 1 palletizer in live production). Headquartered in Richmond, VA, with embedded kitting operations inside client facilities in Richmond, Raleigh, and Salt Lake City for clients with co-located requirements.

// PROCESS

How 3PL kitting and assembly works

Six stages, repeated across every program. The discipline is what catches errors before they reach the retailer.

01
Inbound receiving and inspection
Components arrive and are verified against the bill of materials. At least one carton is opened per pallet per SKU to catch vendor concealed shortages before production begins — the most common source of inventory error in kitting operations.
02
Inventory slotting and work cell setup
Components are positioned in the work cell to minimize pick travel and maximize throughput. High-velocity components go in the golden zone (waist height, arm's reach). Scan gun configurations are built per program before the line starts.
03
Pick and kit with scan verification
Operators pull components per the bill of materials and assemble the finished unit. Scan gun verification at each pick maintains inventory accuracy above 99% across programs running 1,000+ SKU movements per day.
04
Quality inspection
Barcode verification, weight check, and photo documentation confirm accuracy at the unit level. Units that fail inspection are pulled and reworked before moving to labeling. This step prevents compliance failures from reaching the retailer.
05
Compliance labeling
Retailer-specific labels, UCC-128 case labels, and GS1 barcodes are applied per retailer specification. Productiv is pre-wired for Walmart, Target, Costco, and 30+ other retail partners — labeling specs are maintained in the WMS and applied automatically per program.
06
Pack out, ASN transmission, and post-job reconciliation
Finished kits are packed and sealed. The EDI 856 ASN is transmitted to the retailer within the required window. Extras, shorts, and damages are documented and reconciled in the WMS before the job closes — preventing the chargeback-triggering discrepancies that happen when inventory records don't match physical shipments.

// RETAIL_COMPLIANCE

// OPERATOR_BUILT

20 years of solved kitting problems

Most kitting problems aren't new. Vendor concealed shortages, First Article mismatches, lot control gaps, count discrepancies on program transfers — we've seen all of them, solved all of them, and built tools to prevent them from recurring.

When you start a program with Productiv, you're not paying for us to learn your industry. You're inheriting 20 years of solved problems.

"We are hitting all the SLAs over and over again. Productiv has led the charge and brought so many improvements to the table over the last two years. There's nothing glaring that stands out anymore and now we are just fine tuning."
Kelli Overson, EVP of Operations — Pourri

W2-only workforce. No temp agencies.

Every operator on your program is a Productiv W2 employee. Line leads, supervisors, and account coordinators average 10+ years of tenure. The institutional knowledge stays on your program — not cycling through every 90 days.

ProQuality — First Article before every run.

Our operator-built AI quality tool auto-routes First Article photos to your team for approval before the full run begins. The most common source of kitting errors — incorrect configuration approved verbally but not validated — is eliminated at the start.

Per-unit pricing. No hourly billing.

You pay per kit, not per hour. That means our incentive is to build kits faster and more accurately — not to bill more time. Efficiency gains flow to you as lower cost per unit, not to us as margin padding.

Cobots and humanoids in live production.

13 cobots, 2 humanoid robots, and 1 palletizing robot run alongside human operators on kitting lines at our Dallas facility. Robot pick accuracy has reached 99%+ on validated SKUs. Every program benefits from the ongoing improvement as robot capabilities expand.
