Cart.com

Cart.com combines an owned 14-facility U.S. fulfillment network with proprietary Constellation software (OMS, WMS, TMS) and managed services for marketplaces, marketing and customer support. It's a strong consolidation play for mid-market and enterprise omnichannel brands, backed by 99% 2-day ground coverage claims and 70M+ orders per year. Pricing is custom-quote only, and low-volume brands will find the model built for someone bigger.

Cart.com is the truest like-for-like on this list. Like Stord, it pairs an owned US fulfillment network — 14 facilities — with a proprietary software layer, Constellation, spanning OMS, WMS, and TMS, aimed at mid-market and enterprise brands running DTC, retail, and marketplace channels from shared inventory. It goes further than Stord on services, adding managed marketplace, marketing, and customer-support teams, so it suits brands consolidating more than fulfillment. The tradeoffs cut both ways. Cart.com assembled its stack through a dozen-plus acquisitions where Stord built more of its own, so ask early which acquired facility and which system you will actually land on. And like Stord, it publishes no rates and no order minimum, so you are in a sales cycle either way. For a brand that likes the consolidation thesis but wants more than fulfillment under one roof, it is the first call.

Cart.com fits brands for which Amazon is one large channel inside a broader marketplace, retail, and DTC operation. It supports those channels from shared inventory across a 17-facility U.S. network, with enterprise software and retail-compliance capabilities for mid-market and larger brands. Cart.com also raised $180 million in March 2026. It rates 4.1 overall and publishes support for FBA prep, FBM, and SFP requirements. For an Amazon-only or early-stage seller, the platform is likely more than the job requires.
