Why Work with Guardian for Fulfillment

We’re not a faceless 3PL. We’re a packaging supplier with a vetted fulfillment

network and a single point of contact you can actually reach.

Nationwide Fulfillment Network

We work with fulfillment partners across California and the United States, so we can put your inventory closer to your customers and keep outbound freight costs in check.

Packaging Supplier Built In

We supply the boxes, bags, tape, and inserts. No coordinating between a separate packaging vendor and a 3PL. One call, one invoice.

Flat Per-Unit Pricing

You know your cost before we start. No surprise labor charges or accessorial fees. We quote per-kit and stick to it.

QC on Every Run

Each kit goes through a QC check before it ships. We catch problems before your customer does.

One Point of Contact

You work with Guardian, not a ticketing system. We manage the partner relationship on your behalf, so you get fast answers and quick adjustments without dealing with multiple vendors.

Fast Turnaround

Stock components ship same or next day. Custom kit runs are quoted with a realistic turnaround based on your volume and complexity.

Minimums vary by project complexity and volume. We work with brands at various stages, from small launch runs to ongoing high-volume programs. Contact us and we’ll let you know what makes sense for your situation.

Do you supply the packaging or do I need to bring my own?

We can supply boxes, bags, tissue, tape, labels, and inserts, or work with components you provide. Many clients use us for both the packaging supply and the kitting labor, which simplifies logistics and billing.
