How to Choose the Best 3PL for
Subscription Box Kitting and Fulfillment

If you’re growing a subscription box brand, congratulations—you’re in an exciting (and sometimes chaotic!) stage. But one of the most critical decisions you’ll make? Choosing the right 3PL for subscription box kitting and fulfillment.

At Sidekick Kitting, we know subscription box fulfillment isn’t just about packing products into a box. It’s about telling your story, delivering an unforgettable experience, and building customer loyalty—every single month.

Let’s dive into what you should be looking for in a 3PL—and why brands like Teak & Twine, Minny & Paul, Science Friday, and Barnes & Noble trust Sidekick Kitting to bring their subscription dreams to life.

What Is a 3PL for Subscription Boxes?

3PL stands for Third-Party Logistics—but at Sidekick Kitting, it also stands for “Third-Party Love” because we treat your products and your customers like they’re our own.

A true 3PL for subscription boxes doesn’t just warehouse your goods—they specialize in kitting and fulfillment, meaning they carefully assemble, package, and ship your curated boxes exactly the way you envisioned them.

Not all 3PLs are set up for subscription box fulfillment.
Choosing the wrong partner could mean delays, errors, or unhappy customers.
Choosing the right partner (hint: Sidekick Kitting!) means peace of mind and a customer experience that shines.

1. Look for a 3PL with Kitting Expertise

If your boxes include 10+ items, customized inserts, or layered packaging, you need a team that lives for complex kitting.

At Sidekick Kitting:

Our fulfillment floor buzzes with energy every day thanks to Luis and Alejandro, our warehouse managers, who oversee the fast-moving magic of kitting in action. No detail is too small for them to catch.

2. Choose a 3PL That Can Scale with You

Today you might ship 500 boxes a month.

Tomorrow? 5,000.

Or maybe even 10,000 in a single day (yep, we’ve done that, too).

Our team at Sidekick Kitting is built for speed, flexibility, and flawless scaling.

Whether you’re launching a new subscription line or planning a massive seasonal drop, we can ramp up fast—without sacrificing quality.

We keep your inventory tight and tidy, too.

Bruno, our meticulous inventory master, double-checks every incoming and outgoing SKU, so you’re never caught short on launch day.
