Why Complex Kitting Projects Need a Specialist, Not Just Any 3PL
You’ve spent months designing the perfect curated box. The products are sourced. The packaging is beautiful. The inserts are ready.
Now you just need a fulfillment partner to assemble everything flawlessly, right?
Spoiler alert: Not every 3PL is up for the job. When it comes to complex kitting and fulfillment, you don’t need just any warehouse—you need a specialist. That’s where Sidekick Kitting shines.
Let’s talk about why complex kitting projects require expertise, creativity, and energy—and why Sidekick is trusted by brands like Teak & Twine, Minny & Paul, Science Friday, and Barnes & Noble to pull off their most detailed projects.
What is Complex Kitting?

Complex kitting means assembling multiple products—often from different vendors—into a carefully curated package that looks intentional, feels premium, and matches your brand perfectly.
It usually involves:
- 5, 10, even 20+ SKUs per kit
- Custom packaging (tissue, crinkle fill, belly bands, stickers)
- Special inserts, notes, coupons, or brochures
- Careful layering or product sequencing
- Personalized touches (like name tags or gift messages)
And it’s a whole different ballgame than basic pick-and-pack fulfillment.
Real Talk from Sidekick:
When we built thousands of science kits for Science Friday, each kit had delicate lab equipment, experiments, and instruction sheets—all layered just so to keep everything intact during shipping.
Simple packing? Not even close.
Complex kitting is an art and a science.
Why Most 3PLs Struggle with Complex Kitting
The truth is, most 3PLs are optimized for speed, not complexity.
They’re built to:
- Pick 1–2 SKUs per order
- Use generic boxes
- Ship as quickly and cheaply as possible
When faced with:
- 15 components
- Custom box assembly
- Crinkle fill layered a certain way
- Gift notes tucked neatly under lids…
Most traditional 3PLs crumble. Mistakes happen. Deadlines slip. Branding suffers.
