General fulfillment operation with a verified FBA prep service. Never ranked and never counted in our prep-specialist stats.

Editor summary

One Stop Prep is a Nashua, New Hampshire operator registered as an LLC in July 2022 and in Good Standing on the state register, working out of office and warehouse space at 1 Chestnut Street. It was a pure Amazon prep center as recently as January 2025 and now runs as a full-service 3PL covering DTC, TikTok Shop, Walmart, eBay, returns recovery, and storage, which is how we type it. The prep line is still the only service it prices publicly, and that card is more detailed than any other third-party logistics operator we list: online arbitrage at $1.47 per unit on shipments over 50 items, falling to $1.35 above 15,000 units, wholesale at $0.97 falling to $0.85, and merchant fulfilled orders at $2.99 plus $0.50 per additional item. Two things to weigh before you send inventory. A 250-unit monthly minimum applies with a $99 monthly fee below it, and Amazon sellers need a Professional Seller account, so this is a poor fit for low or seasonal volume. And the homepage timeline claims a 2018 founding that the New Hampshire register, the domain record, and the operator's own About page all put at 2022. Its published customer and order counts do not reconcile with each other either, so treat every volume figure on the site as unverified.
