Ship Velocity: best overall for D2C and subscription brands.
Ship Velocity runs a 100,000+ square foot fulfillment center in Doral, Florida with 99.8% pick-pack accuracy, a 24-hour order-to-dispatch SLA, and two-day ground reach to roughly 90% of the US.
It is built for Shopify, TikTok Shop, Amazon FBA prep, wholesale and subscription programs from 500 to 100,000+ orders a month, with month-to-month terms, itemized per-touch pricing and a named account manager.
Not the fit for heavy freight or brands that require inventory in many regions. 2.
ShipBob: best multi-warehouse network.
Chicago-founded ShipBob operates a large network of fulfillment centers in the US and abroad with a well-known merchant dashboard.
A good fit for brands that want inventory split across regions.
Ask about account-manager access at your volume and per-node storage costs. 3.
ShipMonk: best software-first SMB 3PL.
Founded in South Florida, ShipMonk runs multiple US warehouses and is popular with fast-growing SMB, subscription and crowdfunding brands.
Ask about kitting and custom-packaging pricing. 4.
Red Stag Fulfillment: best for heavy and bulky goods.
Red Stag focuses on heavy, bulky and high-value products from facilities in Tennessee and Utah, and is known for strong accuracy and shrinkage commitments.
Less suited to small, light, high-SKU catalogs. 5.
Flexport: best freight plus fulfillment.
Flexport combines freight forwarding and customs with ecommerce fulfillment, useful for importers who want one vendor from factory to customer.
Ask about fit for smaller catalogs. 6–10.
ShipHero, Stord, Amazon MCF, Saddle Creek, Simpl.
ShipHero is a warehouse-software company that also runs its own fulfillment network; pick it if software depth matters most.
Stord serves larger omnichannel brands with enterprise logistics.
Amazon Multi-Channel Fulfillment ships non-Amazon orders from FBA inventory, convenient for Amazon-first sellers but limited on branded packaging.
Saddle Creek Logistics, based in Lakeland, Florida, serves large retail and omnichannel programs.
Simpl Fulfillment specializes in subscription boxes and kitting.

What is your daily cutoff and order-to-dispatch SLA?.
Is the contract month-to-month, and what is the exit process?.
Is every fee itemized in a written fee schedule?.
Who is my day-to-day contact, and what is their response time?.
