FBA prep centers in Colorado.

Summit FBA is an Amazon FBA prep and kitting company in the Denver area; its Colorado filing (Summit FBA, LLC, formed July 2025) lists 5715 Fairfax Street in Commerce City. For Amazon it polybags or boxes units and applies FNSKU labels, builds bundles, preps case packs with FBA box ID labels, and consolidates or cross-docks shipments into Amazon. It also takes on project kitting and assembly such as subscription boxes and retail sets. Rates are published: $0.75 per unit for 100 to 1,999 units of polybagging or boxing with FNSKU labeling (label cost included; the card also lists a standard poly bag as a $0.20 add-on), falling to $0.65 at 3,000 to 4,999, plus $1.50 per carton for case packs, $10 per pallet received, $350 to $450 per container unload, and storage at $5 per pallet per week. Cautions: the contact-information page on its website gives a different street address, 6750 East 46th Avenue Drive in Denver, so ask which building receives your inventory. The company was formed in July 2025, so its claim of millions of units prepped is not independently confirmed. Its email address appears only on its policy and accessibility pages, not its contact page; the phone and quote form are the main contact routes.

Kitting & Assembly Solutions is a kitting and contract-packaging warehouse in Commerce City, CO, in the Denver metro, whose lead offer is Amazon FBA prep: receiving, inspection, labeling and barcoding, poly bagging, bundling, tagging, kit assembly, and shipment to Amazon by UPS or another Amazon-partnered carrier. The Colorado LLC was formed in June 2014 and its state record reads Good Standing as of 2026-09-28; owner Todd Peters is confirmed by LinkedIn and press coverage. Pricing is quote-based with no public rate card. Google shows a 5.0 rating across 27 reviews as of 2026-09-28 (the on-site widget still reads 20), several from Amazon sellers describing OA prep and multi-year relationships. Disclosure: FBA prep leads the homepage, but the company's core identity is kitting, assembly, and contract packaging, so seller inventory shares the warehouse with packaging work.

Fulfillment CO is a Colorado Springs 3PL at 3380 N El Paso Street, registered with the state as Fulfillment Co, LLC since February 2020 on a domain that dates to 2010. Direct-to-consumer pick and pack is the main line, with FBA prep run as a dedicated service alongside it. The prep page is specific about inbound work: they receive palletized and non-palletized freight, check it against what the supplier was paid for, then kit, bundle and assemble products and prepare cartons to Amazon fulfillment center requirements. They accept goods that arrive non-barcoded and non-polybagged, run year-round flat-rate storage instead of Amazon's seasonal tiers, and also handle MFN and Seller Fulfilled Prime orders. They state no minimum order volume. One thing to weigh: no prep rates are published anywhere, so every price is a quote. The same owners run The Mail Center retail store in the same city.

QuickBox is an ecommerce fulfillment company headquartered at 11551 E 45th Ave in Denver, Colorado, with warehouses it lists in Atlanta, Dallas, Denver, the Inland Empire, Los Angeles, Memphis and New York/New Jersey. The main business is direct-to-consumer, retail and subscription fulfillment for beauty, supplement and consumer-goods brands. Amazon FBA prep is a separate line run by its special projects team: ASIN and FNSKU unit labels, master carton and pallet labels, lot and expiration assignment, polybagging, 100% inspection of FBA orders, and scheduling shipments into Amazon fulfillment centers, with consolidated Amazon freight across clients. The prep page states a 72-hour turnaround per FBA prep order. The company also runs FBM fulfillment from its own warehouses. Pricing is by quote. The Colorado LLC was formed in October 2009 and is registered at the Denver headquarters address, and in 2022 it acquired El Mar Logistics in Los Angeles. Cautions: this is a large general 3PL, not a prep specialist, and its client base skews toward established brands. The site does not say which building handles FBA prep. The FDA-registered facilities claim is the company's own and was not checked.
