We help ecommerce brands, Amazon sellers, and marketplace merchants lower their storage, prep, and fulfillment costs—without sacrificing speed, compliance, or customer experience.







Masterpax Fulfillment is a boutique 3PL and prep center for growing ecommerce businesses. We work with DTC brands, Amazon and Walmart sellers, and online retailers who want to get out of fulfillment headaches and focus on scaling their business.
From container unloading to gift-ready packaging, Masterpax gives ecommerce and marketplace sellers a boutique 3PL partner that protects margins, brand experience, and compliance.
We pick, pack and ship any of your online marketplace orders with a focus on presentation and unboxing.
We don’t just prep; we protect your listings from compliance headaches. Masterpax supports Amazon FBA/FBM, Walmart WFS, and other marketplaces with policy-aware prep and free consultations for active clients.
Our warehouse is designed to be a smarter alternative to FBA/WFS storage. We help you cut FBA/WFS-related storage and prep costs by up to 40–60% while keeping your supply chain flowing.
Returns don’t have to be chaos or pure loss. We process returns from Amazon, Walmart, Shopify, and other channels with a focus on recovery, not just disposal.
You’re never just a warehouse number here. Masterpax is intentionally boutique—so you get direct access to real people who understand your catalog, your channels, and your goals.
Every business is different. Choose the plan that fits your stage and we’ll tailor storage, prep, and fulfillment rates to your exact needs.

Real stories from ecommerce and marketplace sellers who partnered with Masterpax to streamline prep, storage, and fulfillment.
Outsourcing to Masterpax was the best move we made this year. Our Amazon and Shopify orders are finally running smoothly, and I’m spending my time on marketing instead of chasing boxes and tracking numbers.
Founder, BrightNest Home
I used to dread FBA prep. Since switching to Masterpax, shipments are compliant, on time, and my storage costs are actually predictable. It feels like I finally have a real operations partner, not just a warehouse.
Amazon FBA Seller
We run a DTC brand plus marketplace sales, so we needed a 3PL that could handle both. Masterpax built a workflow around our business instead of forcing us into a rigid system. The communication and transparency have been outstanding.

As a growing brand, I didn’t want to feel like a tiny client in a huge warehouse. With Masterpax, I actually know who’s handling my products, and they pay attention to packaging and presentation like it’s their own brand.

Our pricing is based on a few main components: receiving, storage, prep/handling, and order fulfillment. Rates depend on volume, product type, and services required. Instead of one-size-fits-all pricing, we review your catalog and order flow, then give you a clear, custom quote with no hidden fees.
