Evaluate fulfillment partners like an operator.

Spreetail earns a 3.7/5 editorial score in this review because its documented capability fits established big-and-bulky brands well, while accuracy and merchant support remain provisional because audited figures were not verified in public evidence. Two models exist: wholesale, where Spreetail buys inventory and manages selling, and quote-only fulfillment, where you keep listing, pricing and advertising control. Confirm fees, eligibility for Seller Fulfilled Prime, minimums and network scope in a written proposal before committing.

Weber Logistics earns 3.8/5 in our editorial assessment for importers and consumer-goods brands with substantial West Coast distribution needs. Its systems, operating controls and port-to-distribution service range are strengths; quote transparency and limited independent performance evidence temper the score. Confirm the proposed facilities, integration scope and total account cost before choosing it.

A third-party logistics provider (3PL) executes work such as warehousing, fulfillment, and shipping. A fourth-party logistics provider (4PL) orchestrates the wider supply chain, coordinating multiple providers and taking broader accountability for outcomes. Choose by contract scope and governance load. Asset ownership, order volume, and the higher number do not decide the fit.

Choose Amazon FBA for fast-turning, standard-size Amazon orders when Prime delivery is central. Choose a 3PL for multi-channel, branded, B2B, oversized, or complex fulfillment. For one non-apparel 1.25+ to 1.5 lb large-standard unit, Amazon's published $5.37 FBA fulfillment fee becomes about $5.56 after the current 3.5% surcharge, as of August 26, 2026.
