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:

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:

Why Sidekick Kitting Specializes in Complex Kitting

At Sidekick Kitting, we live for the complicated projects.

Here’s what makes us different:

1. Dedicated Kitting Experts

You won’t get a generic warehouse team here. You’ll get Bruno checking your inventory meticulously at intake. You’ll get Luis and Alejandro running precise kitting lines on the warehouse floor. And you’ll have Annie and Jen—our powerhouse project managers—keeping your project moving smoothly, with constant updates.

2. Custom Setup for Each Project

Every kitting project gets its own customized assembly process.

When we fulfilled over 1,000,000 gift boxes for Teak & Twine, each box had to meet strict brand guidelines—and every assembly line was set up specifically for that box.

3. Scale Without Sacrificing Quality

Can we kit 10,000 boxes in a single day?

Can we do it while keeping every box looking perfect?

When Minny & Paul needed thousands of small-batch gift sets assembled with branded cards and gift notes, we didn’t just get it done—we got it done beautifully.
