Best 3PL Fulfillment Services for Ecommerce

When You Need a 3PL

A third-party logistics provider makes sense when the time you spend on fulfillment is worth more than the per-order cost of outsourcing. If you are processing 200 or more orders per month and spending 3 to 5 hours daily packing and shipping, that time has a real cost. At even $30 per hour of your time, 4 hours daily equals $2,400 per month in labor. A 3PL charging $4 to $6 per order for 300 orders costs $1,200 to $1,800, freeing those 80+ hours for marketing, product development, and growth activities that generate revenue.

3PLs also enable capabilities that self-fulfillment cannot easily match. Distributed warehousing, where your inventory is stored in multiple locations across the country, puts products within one or two-day ground shipping distance of most US consumers. Achieving this on your own requires leasing multiple warehouse spaces, hiring staff at each location, and coordinating inventory across sites. A 3PL provides this infrastructure on a variable-cost basis, scaling up during peak seasons and scaling down during slow periods without fixed overhead.

The main trade-offs of using a 3PL are cost per order (higher than self-fulfillment for simple operations), less control over the packing and presentation experience, dependency on a third party for your most customer-facing operation, and minimum volume or revenue requirements that smaller sellers may not meet.

ShipBob: Best Overall for Mid-Volume Sellers

ShipBob operates fulfillment centers across the US (Chicago, Los Angeles, Dallas, New York, and several others), Canada, the UK, Europe, and Australia, giving sellers access to a global distributed fulfillment network. ShipBob connects directly with Shopify, WooCommerce, Amazon, BigCommerce, and other major platforms, automatically importing orders and syncing inventory levels.

Pricing: ShipBob charges separately for receiving ($35 per man-hour for the first two hours, then $45 per hour), storage ($40 per pallet per month, $10 per shelf per month, or $5 per bin per month), pick and pack ($0 for the first four picks per order, then $0.20 per additional pick), standard packaging (included), and shipping (at ShipBob's negotiated carrier rates, which are typically 15% to 25% below published rates). A typical order with one to two items costs $5 to $8 total including shipping for standard ground delivery.

Best for: Sellers processing 200 to 5,000 orders per month who want two-day shipping capability, transparent pricing without hidden fees, and a technology platform with strong analytics and inventory management. ShipBob's distributed inventory feature automatically splits your stock across multiple warehouses to minimize shipping zones and delivery times.

Limitations: ShipBob has minimum order requirements (typically 200+ orders per month to get started). Custom packaging options are limited compared to smaller, more boutique 3PLs. Sellers with very low-cost products (under $10 average selling price) may find the per-order fees eat too much margin.

Flexport (Formerly Deliverr): Best for Marketplace Sellers

Flexport acquired Deliverr in 2022 and combined its freight forwarding expertise with Deliverr's ecommerce fulfillment network. The key advantage is fast delivery badges: Flexport's fulfillment enables two-day delivery tags on Walmart Marketplace, eBay Fast 'N Free, and Wish Express, which boost product visibility and conversion rates on those platforms.

Pricing: Flexport uses an all-in pricing model that bundles pick, pack, and shipping into a single per-unit fulfillment fee based on product dimensions and weight. A small, lightweight item might cost $4 to $5 per unit including shipping, while a medium-sized product runs $6 to $9. Storage fees are $0.75 per cubic foot per month for standard storage and $1.50 for long-term storage (over 6 months). The all-in model makes cost forecasting simpler than ShipBob's itemized pricing.

Best for: Multi-channel sellers who need fast delivery badges on Walmart, eBay, and other marketplaces. Sellers who also import products internationally benefit from Flexport's freight forwarding services, creating an end-to-end supply chain from factory to customer. Flexport's technology platform provides demand forecasting and inventory optimization tools that help with purchase planning.

Limitations: Less customization for packaging and branding than ShipBob or ShipMonk. The all-in pricing model makes it harder to identify exactly where your money goes. Flexport's warehouse network is smaller than ShipBob's, with fewer US locations, though coverage is expanding.

ShipMonk: Best for Subscription Boxes

ShipMonk operates from fulfillment centers in Fort Lauderdale, Los Angeles, and Cranbury (New Jersey), with additional international locations. ShipMonk's differentiator is its kitting and assembly capabilities, which make it the top choice for subscription box businesses that need products assembled into boxes on a recurring schedule.

Pricing: ShipMonk charges a pick and pack fee starting at $3.00 for the first item and $0.75 for each additional item. Kitting services (assembling subscription boxes) are charged per kit assembled. Storage runs $2 per small bin, $4 per medium bin, or $20 per pallet per month. Shipping is billed at ShipMonk's negotiated carrier rates. Total cost per order for a typical two-item order is $5 to $9 depending on size and destination.

Best for: Subscription box businesses, sellers who need kitting or bundling services, and sellers processing 300 to 10,000 orders per month who want a personal account management experience. ShipMonk assigns dedicated account managers at lower volume tiers than most competitors.

Limitations: Fewer warehouse locations than ShipBob or Flexport, which can result in longer transit times for customers far from the three US fulfillment centers. The pricing structure with separate fees for every service can make total costs less predictable.

Red Stag Fulfillment: Best for Heavy and Oversized Products

Red Stag operates from two US fulfillment centers in Knoxville, Tennessee, and Salt Lake City, Utah. The company specializes in heavy, bulky, oversized, and high-value products that other 3PLs either refuse to handle or handle poorly. Red Stag offers a zero-shrinkage guarantee, meaning they pay you the full retail value for any product lost or damaged in their warehouse.

Pricing: Red Stag does not publish standard pricing because rates are customized based on product characteristics and volume. Typical per-order fees range from $5 to $15 depending on product size and weight. Red Stag's pricing is higher than competitors for small, lightweight products but competitive for heavy items because their warehouses and processes are designed for larger products. They offer a 30-day free trial to test their service with real orders.

Best for: Sellers of products over 10 pounds, products requiring special handling (fragile, temperature-sensitive, or hazardous), high-value products where shrinkage and damage protection matter, and sellers who need freight shipping capabilities integrated with their fulfillment workflow.

Limitations: Only two warehouse locations limits geographic distribution. Minimum order requirements are higher than some competitors (typically 500+ orders per month). Not cost-effective for small, lightweight products that other 3PLs handle more efficiently.

Amazon Multi-Channel Fulfillment (MCF)

If you already sell on Amazon FBA and have inventory stored in Amazon's warehouses, Multi-Channel Fulfillment lets you use that same inventory to fulfill orders from your own website, Shopify store, or other marketplaces. Amazon picks, packs, and ships the order using its logistics network, and you pay per-unit fulfillment fees similar to FBA fees.

Pricing: MCF standard shipping (3 to 5 day delivery) costs $5.95 for a small standard item, $7.00 for a large standard item, and higher for oversized products. Expedited (2-day) and priority (next-day) options cost $8.95 to $14.00 and up respectively. These rates include pick, pack, and shipping. Storage fees are the same as FBA storage: $0.87 per cubic foot monthly from January to September and $2.40 per cubic foot from October to December.

Best for: Existing Amazon FBA sellers who want to fulfill orders from other channels without maintaining a separate inventory pool or contracting with a second 3PL. MCF leverages Amazon's unmatched warehouse network and delivery speed infrastructure.

Limitations: Orders ship in Amazon-branded packaging by default, though unbranded packaging is available for an additional $0.50 to $1.00 per unit. You are entirely dependent on Amazon's ecosystem. Amazon may prioritize its own marketplace orders over MCF orders during peak periods. The pricing is not as competitive as dedicated 3PLs for high-volume sellers who can negotiate better rates elsewhere.

How to Choose the Right 3PL

Start by calculating your total current fulfillment cost including labor, warehouse space, packaging materials, and carrier costs. Then get quotes from two to three 3PLs for your specific product dimensions, order volume, and geographic distribution. Compare the total cost per order including all fees, not just the headline pick and pack rate. Factor in the value of your time freed from fulfillment tasks and the potential for faster delivery speeds to improve customer satisfaction and repeat purchase rates.

Request references from current clients in your product category and order volume range. Ship test orders to yourself and friends to evaluate packaging quality, delivery speed, and accuracy. Most 3PLs offer trial periods or money-back guarantees because they know that sellers who experience the service firsthand are more likely to commit.
