Kitting—bundling multiple components into a single package—is a cornerstone service in contract packaging, but the costs can vary wildly depending on complexity, volume, and supplier choice. Understanding what drives pricing and how to negotiate rates will help you avoid overpaying and make smarter outsourcing decisions. Here's what you need to know before getting quotes.
What Kitting Actually Includes
Kitting services go beyond just throwing items together. A contract packager handling kitting typically performs:
- Component sourcing and storage (holding inventory of all sub-items)
- Assembly and bundling (combining items into a single unit)
- Quality verification (checking all components are present and correct)
- Labeling and documentation (adding part numbers, barcodes, assembly instructions)
- Secondary packaging (boxing, palletizing, and shipping-ready presentation)
Some providers also offer light sub-assembly, serialization, and custom inserts or dividers. If your kit requires any of these add-ons, expect higher per-unit costs.
Typical Cost Ranges
Kitting costs typically fall into two categories: setup fees and per-unit labor.
Setup and tooling usually runs $500 to $3,000 depending on kit complexity. A simple five-item kit might require minimal setup; a 15-item kit with custom inserts and barcoding could hit the higher end.
Per-unit labor ranges from $0.50 to $3.00 per kit for straightforward assembly, and can climb to $5+ for intricate or high-touch kits requiring precision placement, testing, or detailed documentation. High-volume runs (10,000+ units annually) typically see lower per-unit rates; low-volume (under 1,000 units) incurs higher per-unit costs or minimum order charges.
Materials—boxes, dividers, labels, padding—are usually billed separately at cost plus a small markup (typically 15–25%).
Volume Matters More Than You Think
A 500-unit annual order will cost you significantly more per unit than a 10,000-unit order. Contract packagers optimize labor and overhead efficiency at scale. If you're running small volumes, look for providers comfortable with smaller minimums; some will quote $50–$150 per month minimums instead of unit minimums, which can work better for startups.
Seasonal or variable demand? Discuss flexibility clauses with your packager upfront. Many will lock in rates for committed annual volumes but charge premium rates for overflow or short-notice orders.
Hidden Costs to Negotiate
- Inventory carrying fees: Some packagers charge monthly storage per pallet or bin. This can add $100–$500/month depending on space.
- Demand forecasting penalties: If you miss committed volume or request rush shipments, expect surcharges.
- Component damage and shrinkage: Who absorbs losses? Get this in writing—typically the packager covers shrinkage up to 0.5–1%, then you pay the difference.
- Labeling and customization changes: Each SKU variation or design tweak might require setup fees ($100–$300 per change).
Questions to Ask Before Selecting a Provider
Capacity and lead time: Can they handle your peak volume without delays? Standard lead time is 10–15 days after materials arrive; confirm this in writing.
Quality control process: How do they verify kit completeness? Ask for their defect rate and what happens if a kit ships incomplete.
Technology and visibility: Do they offer real-time inventory tracking and shipment notifications? Basic providers might only offer weekly reports.
Pricing transparency: Request a detailed quote breaking down setup, per-unit labor, materials, storage, and any per-change fees. Never accept vague "time and materials" proposals.
References: Ask for two or three customers with similar kit complexity and volume to yours. Contact them directly about on-time delivery and quality.
If you're comparing multiple providers, platforms like Mercoly let you request quotes from trusted contract packaging suppliers in your region and compare pricing side-by-side, saving time on RFQ rounds.
Frequently Asked Questions
Q: Is kitting cheaper than doing it in-house? For volumes under 2,000 units annually, outsourcing is usually cheaper when you factor in labor, storage, and equipment. Above 5,000 units, the math depends on your available labor and space.
Q: What's the typical defect rate I should expect? Most reputable contract packagers target 0.1–0.5% defect rates (missing or damaged items per kit shipped); anything above 1% signals quality control issues.
Q: Can a packager handle multiple kit variants in one order? Yes, but each SKU variant typically incurs separate setup fees and slower throughput; confirm they can run mixed-SKU orders without significant delays or minimum splits.
