Amazon selling puts fulfillment under a microscope as few other channels do. Late shipments, inventory errors, and non-compliant labeling can destroy a seller’s account health before any second chance materialises. The best 3PL companies for brands selling on Amazon go well beyond picking and packing; they manage the platform-specific requirements that routinely trip up internal teams.
Finding the right 3PL for Amazon sellers
Amazon’s fulfillment standards are unforgiving. Sellers operating under Fulfilled by Merchant (FBM) must hit tight ship-time windows, while those enrolled in Seller-Fulfilled Prime face even stricter service-level commitments. Brands supplying Amazon as a vendor need EDI compliance, routing-guide adherence, and chargeback management baked into every workflow. Any 3PL stepping into that environment has to be fluent in all of it.
1. Rush Order
Founded in 1989 and based in Gilroy, California, Rush Order has spent over 30 years building a fulfillment operation designed around the needs of growing e-commerce brands. The company operates 13 locations across North America, Europe, Asia, and Australia, a footprint that suits brands selling globally, not just domestically.
What it does: Rush Order handles B2C fulfillment, retailer EDI, retailer logistics, accounts receivable, accounting compliance, and turnkey back-office solutions. The platform integrates with Shopify, WooCommerce, Amazon, and NetSuite.
Where it shines: Accuracy is built into the picking workflow. Barcode verification runs at multiple checkpoints, which practically eliminates human error at the pack station. Most orders placed before 2 p.m. ship the same day. Clients get a real-time dashboard showing inventory levels, order status, and shipment tracking across all sales channels. That kind of visibility matters when Amazon’s seller metrics are on the line. One client, Vogmask, used Rush Order to scale rapidly during a period of sudden demand without adding major internal headcount.
2. Speed Commerce
Founded in 1983 and headquartered in Las Vegas, Nevada, Speed Commerce serves retailers and manufacturers across the United States and Canada. The company runs fulfillment centers in Pennsylvania, Ohio, Missouri, and Texas, all equipped with automation including unit sortation, pick-to-pack conveyors, and radio-frequency scanning.
What it does: Speed Commerce covers order fulfillment, warehousing, kitting and assembly, returns management, digital marketing, and ecommerce technology, including web platform development and hosting. It integrates with Shopify, Magento, and WooCommerce.
Where it shines: The company owns and maintains its own software platforms rather than licensing third-party tools, which allows for more tailored services.
3. 3PL Center
Founded in 2011, 3PL Center is a family-owned business led by founder and CEO Marcos Eddi, with three generations of logistics experience behind the operation. The company is headquartered in Edison, New Jersey, with additional facilities in Robbinsville, New Jersey, and Simi Valley, California.
What it does: Services include pick-and-pack, kitting and assembly, labeling and compliance, returns management, and same-day shipping. A 24/7 web-based warehouse management system gives clients real-time tracking across orders.
Where it shines: 3PL Center’s client list includes Bearaby, which relies on the company for both B2B and B2C fulfillment, including routing orders for Nordstrom and Saks. Acebright uses 3PL Center for lot tracking and expiration-date-based shipping inside food-grade warehousing.
4. ShipMonk
ShipMonk was founded in 2014 and calls Fort Lauderdale, Florida home. The company has expanded to more than 2,000 team members spread across 12 facilities in the US, Canada, Mexico, and Europe. It’s built specifically for e-commerce brands shipping 500 or more orders per month.
What it does: ShipMonk handles order fulfillment, inventory management, shipping management, and warehouse management for DTC, B2B, and retail channels. The company’s Virtual Carrier Network (VCN) consolidates carrier options for shipping management.
Where it shines: ShipMonk claims 99.9% order accuracy and has built automated systems that manage high SKU counts, complex kitting, and seasonal volume spikes. The company has appeared on the Inc. 5000 list of fastest-growing private companies for five consecutive years and on Deloitte’s Technology Fast 500. Clients include Dr. Squatch, 4Ocean, and BEARD KING. ShipMonk’s entry threshold of 500 monthly orders makes it less accessible for early-stage brands still building volume.
5. ShipBob
ShipBob was founded in 2014 and is headquartered in Chicago, Illinois. The company operates 60 or more fulfillment centers across the US, Canada, the UK, EU, and Australia, and has fulfilled over 200 million orders to date. It serves more than 5,000 direct-to-consumer businesses.
What it does: ShipBob combines order management, inventory management, warehouse management, predictive analytics, and shipping management in one platform. The software is free for all customers and integrates with Shopify, Amazon, eBay, Magento, and others.
Where it shines: ShipBob’s scale is genuinely hard to match. Its network of 60-plus facilities lets brands distribute inventory closer to customers, cutting transit times and shipping costs. Clients include Touchland, TB12, 100 Thieves, and the Savannah Bananas baseball league. Most e-commerce businesses pay between $5 to $10 per order for fulfillment.
Capabilities that matter for Amazon fulfillment
Not every 3PL speaks Amazon fluently. A few capabilities separate the ones that work well on the platform from the ones that create problems.
EDI and routing compliance is table stakes for brands selling as Amazon vendors. Routing guide violations generate chargebacks, and enough chargebacks can end a vendor relationship. A 3PL that handles retailer EDI natively, not as an add-on, matters here.
Real-time inventory visibility across channels prevents the overselling and stockout scenarios that hurt Amazon search ranking. Any 3PL worth considering should offer a live dashboard that syncs with a seller’s Amazon inventory.
Multi-location networks reduce average transit time and shipping cost, both of which feed into the customer experience metrics Amazon tracks. A single warehouse works for early-stage brands; a distributed network becomes important at scale.
And returns management is often underweighted in the selection process. Amazon’s return rates average around 5% to 15% depending on category.
Bottom Line
The best 3PL companies for brands selling on Amazon tend to share a handful of traits: platform-native integrations, same-day fulfillment windows, and the operational infrastructure to stay compliant with Amazon’s requirements. But the right fit depends on where a brand actually stands today.
