Your warehouse department — not just your 3PL.
Most 3PLs operate like a transactional vendor: you ship inventory in, orders ship out, and you hope nothing breaks in between. We operate differently. Our team works as an extension of your operations — thinking in solutions, watching for issues before they reach your customer, and bringing aerospace-grade quality assurance to every box that leaves the dock.
That means we know your SKU mix. We know which products tend to ship together. We know which packaging your brand uses on which channel. And we proactively flag what we see, so you can make decisions before they become problems.
- Dedicated account lead — direct phone & email
- Proactive issue flagging, not after-the-fact reports
- Custom standard operating procedures per brand
- Photo documentation for every kit, every inbound, every exception
From your dock to your customer's doorstep.
Four steps. Every step scan-verified. Every step documented. No black boxes.
Receiving
Containers from the Port of Long Beach arrive at our dock the same day. Every SKU counted, photographed, and put away within 24 hours.
Picking
Orders flow into the picking queue within seconds. Pickers scan-verify every barcode. The WMS rejects mismatches in real time — 99.8% accuracy.
Packing
Branded packout per your spec. Your boxes, your tissue, your inserts. Every unit re-scanned at pack station for a second verification check.
Shipping
Rate-shopped across USPS, UPS, FedEx, DHL. Same-day at 2 PM Pacific. Tracking pushes back to your platform within minutes of label print.
One inventory pool. Every sales channel. Zero overselling.
Your Shopify, Amazon FBM, Walmart Marketplace, TikTok Shop, and B2B EDI orders all flow into the same warehouse, against the same inventory pool. When a customer buys the last unit on Shopify, Amazon and Walmart update in the same minute. No batch syncs, no nightly delays, no manual reconciliation.
We utilize ShipHero WMS — the same warehouse management system used by DTC brands shipping millions of orders per year. Native API integrations to 20+ platforms. EDI support for major retailers via SPS Commerce. Custom API connections for everything else.
- 20+ native platform integrations
- Real-time bi-directional inventory sync
- Channel-specific routing rules & SLAs
- Full EDI: 850 / 856 / 810 / 940

The substance behind the marketing.
Every 3PL claims "same-day shipping" and "great service." Here's what actually backs ours up — operationally, financially, contractually.
Same-day cutoff at 2 PM Pacific
Orders received by 2 PM Pacific ship the same business day with tracking pushed back to your storefront within minutes of label generation. Late-arriving orders ship the next morning — not 24 hours later.
We utilize ShipHero WMS
We run the same warehouse management system that powers DTC brands shipping millions of orders per year. Real-time inventory, batch picking, scan-pack workflow, native API integrations — not a homegrown legacy system.
Ships from Los Angeles
Minutes from the Ports of Los Angeles and Long Beach. Two-day ground to the entire West Coast, three to four-day to most of the US. If your supplier ships from Asia, your inventory hits our dock days faster than an East Coast 3PL.
One human, not a ticket queue
You get a direct phone number and email for your dedicated account lead — not a generic support@ inbox or a ticket portal. When something goes wrong, you talk to the person who can actually fix it.
No order minimums, no setup fees
Onboard while you're still shipping 50 orders a month. Or onboard at 50,000. Same software, same pricing structure, same team. No setup fees, no platform fees, no account management charges.
Month-to-month, no contract
30-day notice to leave. We don't lock you in. The only reason a 3PL needs a long-term contract is to compensate for service customers would otherwise walk away from — and we'd rather earn the relationship each month.
What brands say after switching to Matrix.
Real operators, real operations, real outcomes. Brand names anonymized at request — full references available on call.
We switched from a big national 3PL that treated us like a number. Matrix gave us a direct line to the team that actually packs our orders — same humans, every time. Our customer service tickets dropped 40% in the first month after onboarding.
Port proximity is the real deal. Our containers from Shenzhen clear Long Beach and hit their dock the same day. We were getting FBA inbound rolling 6 days faster than our previous East Coast prep service — that's 6 extra days of selling on Amazon, every container.
We needed multi-channel sync that actually worked — Shopify DTC, Amazon FBM, Walmart Marketplace, TikTok Shop, all from one inventory pool. Matrix's ShipHero setup handles it without us thinking about it.
