Colorado for high-volume FBA prep.
The case for Colorado sellers actually pay attention to, plus the caveats we routinely have to remind sellers about during matching calls.
Colorado is a Mountain West reach pick. Amazon's Denver-area FCs, including Aurora and Thornton, sit where I-25 meets I-70, and a Front Range prep center keeps the inbound leg short for sellers whose demand or suppliers sit between the Plains and the Rockies. Colorado charges sales tax, so the case is position, not tax.
The published Colorado roster is three operators, and none is a prep specialist: a Commerce City kitting and contract-packaging warehouse whose lead offer is FBA prep, plus two full-service 3PLs in Denver and Colorado Springs where prep is a line inside general ecommerce fulfillment. All three price prep by quote; none publishes a per-unit rate card.
Where the prep actually sits.
The Denver metro is the operator base: Kitting & Assembly Solutions sits in Commerce City, northeast of downtown, and QuickBox runs its headquarters warehouse on East 45th Avenue in Denver, both inside the metro that holds the Aurora and Thornton FCs. Fulfillment CO works from Colorado Springs, about 70 miles south on I-25. QuickBox also lists warehouses in six other metros and does not say which building handles FBA prep, so ask before you ship.
What sellers miss.
Colorado's state sales tax is 2.9%, but county, city and special-district rates stack on top and many home-rule cities collect their own, so the combined rate depends on the warehouse address. No Colorado operator publishes prep rates, so compare quotes line by line. Kitting & Assembly Solutions publishes no email and is listed but not shortlisted for buyer introductions, and QuickBox's client base skews toward established brands, both noted on the profiles.

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.
QuickBox
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.
Fulfillment CO
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. Two things to weigh. No prep rates are published anywhere, so every price is a quote. The FBA page is written in a deliberately direct, irreverent owner's voice, with strong language in a few places, which is a matter of taste rather than capability, and one of the two FBA pages still sits at a default 'copy-of' URL. The same owners run The Mail Center retail store in the same city.
