How rankings work. Rankings on this page are editorial; we choose them on the criteria below (verification freshness, service breadth, capacity, reliability). Featured listings, when present, are clearly labeled both at the top of the page and on the entry itself. The methodology, criteria, and exclusions stay editorial regardless of any featured placements. New to the category? Start with what FBA prep is. Otherwise, read our full editorial methodology and the verification study.

We order these editorially. Four factors drive placement: verification freshness, service breadth, capacity, and reliability signals. Any center that fails a verification check does not appear here; it appears in exclusions instead. There is no paid placement and no numeric formula to game; the order reflects our editors' read of the four factors below.
Days since our last passing verification check. <= 90d is current; 90 to 180d shows a stale badge; > 180d is flagged and drops out.
Distinct services we've confirmed (prep, kitting, FNSKU, hazmat, photography, etc.). More confirmed services rank higher.
Self-reported and corroborated against seller-forum data. Centers that overstate this drop in rank when we catch the mismatch.

It works with new and international sellers and ships pallets and freight, but does not take retail arbitrage, liquidation, or book sellers at this time. Best fit for sellers who want a simple flat per-unit rate from a long-operating shop.

Stated turnaround is 24 to 72 hours, with FBM, custom kitting, and storage also offered. Best fit for budget-conscious sellers who want tax-free Montana storage and an all-in per-unit rate.
Hainesport, New Jersey FBA prep center since 2021, with public volume-tier per-unit pricing from $0.55/unit.
Why we ranked them here: An Amazon FBA prep center in Hainesport, New Jersey, operating since 2021, that receives, inspects, preps, packs, and ships seller inventory into Amazon. Published per-unit prep is volume-tiered from $0.95/unit (100 to 500) down to $0.55/unit (5,001 to 10,000), where each tier bundles receiving, inspection, FNSKU labeling, poly bagging with suffocation labels, dunnage, sticker covering, and 14 days of free storage, shipping to Amazon in 24 to 48 hours. It runs two dock-high loading docks for small-parcel and LTL freight and serves arbitrage, wholesale, private-label, and international sellers via its own client portal. Best fit for higher-volume sellers who want one of the lowest published per-unit rates in this directory.
Gahanna, Ohio FBA prep center with a public per-unit rate card from $1.00/unit.
Why we ranked them here: An Amazon FBA prep center near Columbus in Gahanna, Ohio, whose homepage leads with wholesale FBA prep. Published per-unit pricing starts at $1.00/unit for a single item covering all Amazon minimum prep requirements, with bundling from $1.25 per bundle, FBM at $2.50/unit, and FBA returns handling at $2.00/unit, plus a $0.10/unit discount for accounts that maintain 2,000 or more units monthly. The operators started as online-marketplace sellers and have run the center for several years. Best fit for wholesale-volume sellers who want a simple low per-unit rate.
Jacksonville, Florida FBA prep center plus done-for-you retail-arbitrage sourcing, per-unit prep from $1.50/item.
Why we ranked them here: A Florida FBA prep center founded by Amazon sellers, based in Jacksonville with a sourcing team in Orlando, that pairs prep with an optional done-for-you retail-arbitrage sourcing service. Published per-unit prep starts at $1.50/item for FNSKU labeling and poly bagging, with bundling, sticker removal, shoe and specialty packaging, FBM, and pallet storage, plus a $300 one-time non-refundable account-activation fee and Inventory Lab required. It has operated for roughly two years. Best fit for sellers who want prep and hands-off sourcing from one provider and do not mind an upfront activation fee.
Cape Coral, Florida FBA returns and removal-order reprocessing specialist, operating since 2008.
Why we ranked them here: A Cape Coral, Florida prep operation specializing in Amazon returns and removal-order reprocessing: it receives a seller unfulfillable inventory and customer returns, runs quality checks, relabels, repackages, bundles, and ships the sellable units back to Amazon FBA. Operating since 2008, it runs a published per-unit rate card with a $40 per-ASIN minimum and a non-optional quality-check step from $0.29/item. The company also runs a separate Romania and EU cargo-forwarding affiliate, with the FBA prep work handled at the Florida warehouse. Best fit for sellers who need unsellable returns and removal orders reworked and sent back into FBA.
Plainfield, Indiana FBA prep with tiered per-unit pricing down to $0.55/unit and no monthly fees or minimums.
Why we ranked them here: Operating since 2023 from Plainfield, IN. The homepage leads with FBA prep: free FNSKU labeling, free standard polybags, and no monthly fees. Tiered per-unit prep is publicly disclosed at $0.75/item (0 to 500 units/month), $0.65/item (501 to 1000), and $0.55/item (1000+), each including receiving, inspection, label removal, bubble wrap, and 30 days of free storage. Also handles bundling and multipacks, online-arbitrage and wholesale prep, dropship relabeling, and Amazon FBM prep. Best fit for cost-sensitive sellers who want no minimums and a clear per-unit rate.
St. Marys, Georgia FBA prep operating since 2015, family-owned, with a published per-service rate card.
Why we ranked them here: One of the longer track records in this directory, operating since 2015 and family-owned by Dustin and Brandy Buchanan. Prep is the productized core: inspection (full exterior plus a sample of contents), FNSKU and special-label application, shrink and bubble wrapping, bundling, book prep, and Amazon returns and used-item reprocessing, plus product photography, palletizing, hazmat handling, and storage. Pricing is itemized on a public per-service rate card (inspection $0.50/unit, label application $0.25, book prep and returns $4.00/unit, photos from $4.00), with unit and bundle prep priced by volume tier. Best fit for sellers who want an established operator and itemized, pay-for-what-you-use pricing.
Sales-tax-free Sisters, Oregon FBA and FBM prep operating since 2022, with a public per-unit rate card and 24-hour FBM.
Why we ranked them here: Family-owned in Sisters, OR (a sales-tax-free state) and operating since 2022. Preps and ships both FBA and FBM orders, with FBM fulfilled within 24 hours, plus bundling, kitting, box forwarding, product photos, quality inspection, returns, storage, and multi-channel fulfillment for Etsy and eBay. Per-unit FBA pricing is publicly disclosed, from $2.00/unit (0 to 500 units/month) down to $1.25/unit (4,000+), with per-size FBM rates. A $250 deposit at signing, a weekly minimum of about 100 items, and a waitlist when the roster is full. Best fit for FBA-plus-FBM sellers who want tax-free Oregon storage and fast FBM turnaround.
Fort Worth, Texas multi-service operator since 2020 with FBA prep productized on a volume-tier rate card down to $0.75/unit.
Why we ranked them here: Operating since 2020 and founded by James McConnell. A multi-service operator (it also runs DTC, wholesale, Walmart WFS, and B2B fulfillment) with Amazon FBA prep as its productized core: a volume-tiered per-unit rate card from $1.50/unit (500 to 1,000 units/month) down to $0.75/unit (3,000+), nine core services per tier, and an itemized add-on schedule (bundling, oversize, inserts, sticker removal). Third-party reviews are public on Trustpilot (4 stars across 11 reviews) and Clutch. Listed with Path C disclosure: multi-service, FBA-prep-primary. Best fit for sellers who want one operator across Amazon and other channels with transparent per-unit prep tiers.
Denver-metro kitting and packaging warehouse operating since 2014, with FBA prep as its lead offer and 20 public Google reviews.
Why we ranked them here: Commerce City, CO operator whose Colorado LLC has been in good standing since June 2014, owned by Todd Peters. The homepage leads with Amazon FBA prep (receiving, inspection, FNSKU labeling, poly bagging, bundling, kit assembly, and shipment to Amazon by UPS or partnered carriers), while the company's core identity is kitting, assembly, and contract packaging. Pricing is quote-based with no public rate card. The on-site widget shows 5.0 across 20 Google reviews, several from Amazon sellers describing OA prep and multi-year relationships. Listed with Path C disclosure: multi-service, FBA prep leads. Best fit for Denver-area sellers who also need kitting or custom packaging work and don't mind requesting a quote.
Wholesale-only Gahanna, Ohio FBA prep with a flat public rate card: $0.90 per single unit, $1.35 per bundle.
Why we ranked them here: The second Gahanna, OH operator in this directory (a distinct business from Rater Prep Services), online since 2019. The homepage leads with flat-rate per-unit prep: $0.90 per single unit and $1.35 per bundle of up to 6 items, with resource-intensive items adding $0.50/unit, kitting at $2.50/unit, removal-order processing at $1.50/unit, and new single books at $1.00/unit (100-unit minimum). Strict scope: wholesale only, no retail arbitrage, no oversize, no used books; shipments run through ScanPower. We found no third-party reviews anywhere, so reputation rests on the operator's own claims. Best fit for wholesale sellers in standard size tiers who want a simple flat rate.
Tax-free Great Falls, Montana prep since 2020 with a full public volume-tier card from $1.45 down to $1.00/unit.
Why we ranked them here: Operating since 2020 per archived site captures, with 2023 hiring activity corroborating a physical Great Falls operation. The homepage leads with the per-unit FBA card: $1.45/unit (1 to 500 units/month) stepping down to $1.00/unit (5,001 to 10,000), including receiving, inspection, poly bagging, FNSKU labels, reused boxes, and dunnage; wholesale runs $1.15 down to $0.90/unit. Storage is free for two weeks, then $2.40/cu ft ($4.80 in Q4). 3PL warehousing and ecommerce fulfillment are secondary lines (Path C disclosure). Honest cautions: we found no third-party customer reviews after roughly six years, and the published contact is a Gmail address. Best fit for sellers who want tax-free Montana storage and a complete published rate card.
Long Island, New York prep with a transparent percentage model: 25% of each ASIN's FBA fee per unit, $1 minimum.
Why we ranked them here: Operated by Lulux Inc, a New York corporation active since 2017; the prep operation dates to 2023. The pricing model is unusual and fully disclosed: 25% of each ASIN's Amazon FBA fee per sellable unit, all-inclusive with a $1.00 minimum, plus a $29.99 monthly service fee and a $500 retainer before first delivery. Storage is free for 30 days, then $5 per pallet per day; payment is ACH, wire, or Zelle only. Also supports FBM and SFP. Honest cautions: the operator deliberately withholds the warehouse street address (we can confirm the state, not the city), and we found a single third-party review in three years. Best fit for New York sellers with low-FBA-fee ASINs who will do their own diligence on service quality.
Waynesboro, Virginia prep built around used-book sellers, registry-confirmed since 2017, listed with a warning.
Why we ranked them here: A genuine niche: the operator states it moves over 10 tons of used books per week, a specialty almost no other prep center serves, alongside private-label prep, storage, and forwarding. The Virginia LLC has been active since July 2017 and co-founder Shanna Mann is confirmed by LinkedIn and local press. There is no current public rate card; the most recent published rates date to January 2022 (book inspection $1.75/unit, storage $0.55/cu ft), so request current pricing directly. This listing carries a warning: at our June 2026 review the homepage's own service links returned 404s and the blog had been quiet since February 2024. Best fit for used-book sellers willing to confirm current operations directly before shipping inventory.
Conroe, Texas FBA prep with a dated public rate card from $1.20/unit and two registry-confirmed owners.
Why we ranked them here: Run by Enzone LLC (Texas filing, active since November 2023) with owners Melissa and Keith Armstrong confirmed by the registry and LinkedIn. The rate card is public and dated March 2026: FNSKU unit processing from $1.20/unit at 400+ units a month ($1.45 below), carton forwarding from $3.50, polybag from $0.75. Budget for the fixed costs: $35 setup plus a $47 monthly membership, which matters at low volume. Six real-named third-party reviews average 5.0 across 16 months. We note honestly that the site footer and the operator's own customer documentation show two different Conroe addresses, likely a move we could not reconcile. Best fit for OA and wholesale sellers near Houston who clear the membership math at their volume.
Family-run prep in tax-free Rochester, New Hampshire with a public card from $1.00/unit at volume.
Why we ranked them here: Registered with the NH Secretary of State since January 2025, in good standing with the 2026 annual report filed, and owner Andrew Tompson confirmed by the registry. The per-unit FBA card is public: $1.75 base down to $1.00 at 3,000+ units a month, with a $199 start-up fee, a roughly $97 to $99 monthly minimum below 300 units (the site lists both figures, which we record rather than resolve), and a 3% payment-processing fee. Requires 1 year of active Amazon selling history. No third-party reviews exist yet, so test responsiveness before committing volume. Best fit for established sellers who want tax-free New Hampshire storage from a small accountable team.
Billings, Montana budget prep from $0.50/unit at volume, listed with a warning for two contract terms.
Why we ranked them here: A small operation in tax-free Billings run by owner Trina Weston, named on the site's own contact page, with a public per-unit card from $1.25 sliding to $0.50 at 10,000+ units a month, FNSKU labeling included, and a $75 one-time registration. This listing carries a warning, and two posted terms deserve attention before you ship: inventory left over 90 days with unpaid storage becomes the operator's property, and the operator disclaims liability for damage or loss in transit to Amazon. The Montana registration could not be checked by automated means, no street address is published, and the 24 five-star reviews live on a single signup-gated directory. Note: this rate card and its terms are identical to Yellowstone Prep and Ship, the older Billings operation listed below; the relationship between the two is unknown. Best fit for price-sensitive sellers who read both clauses and start with a small test shipment.
Billings, Montana prep since 2022 from $0.50/unit at volume, with 55 dated third-party reviews, listed with a warning.
Why we ranked them here: Run by owner Katy Byrd since 2022 in tax-free Billings, with the deepest third-party review record of the Montana centers we list: 55 dated reviews at 5.0 on a prep-industry directory spanning 2024 to 2026, plus a 4.5-of-5 Walmart marketplace seller rating. The per-unit card is public: $1.25 sliding to $0.50 at 10,000+ units a month with FNSKU labeling included, a $75 one-time registration, and 24-48 hour typical turnaround. The warning covers two things: inventory left over 90 days with unpaid storage becomes the operator's property under their posted terms, and the website carries live Wix template debris (a placeholder shop and template service pages), so rely on the price sheet and direct contact. Tailwind Pack & Ship, also in Billings, publishes an identical rate card; Yellowstone's is the older operation. Best fit for OA and wholesale sellers who want tax-free Montana storage with a visible review history.
Newark, Delaware multi-service prep operating since 2022, with public volume-tier per-unit pricing and a 25,000 sq ft tax-free facility.
Why we ranked them here: Founded 2022 by Anthony Tomlinson and Ethan Ward (predecessor brand Dash Fulfillment), running a primary 25,000 sq ft facility at 301 Ruthar Drive plus a 10,000 sq ft site in Bear. FBA and Walmart WFS prep is the productized core, with public volume-tier rates: wholesale prep $0.70 down to $0.55/unit and online-arbitrage prep $1.50 down to $1.00/unit. Storage is free 14 days then $0.01/unit/day. Alongside prep it offers FBM and DTC order fulfillment (same-day before the 7am EST cutoff), two-step dropshipping, and FTL inbound consolidation at $0.20 to $0.50/lb, so confirm scope if you want a prep-only relationship. Accepts hazmat. This location at 301 Ruthar Drive is independently verified and is distinct from the unrelated Newark prep cluster on Executive Drive and 310 Ruthar; the Delaware registry filing date could not be checked by automated means and the pricing nav link 404s (rates live on the service pages). Best fit for sellers who want tax-free Delaware storage and a single operator across prep plus fulfillment.
Flagged: our most recent check could not reach this operator (website unreachable). Confirm directly before committing volume; see the profile for detail.
Tax-free New Hampshire prep founded 2022, 15,000 sq ft, with publicly-disclosed volume-tier pricing across arbitrage, wholesale, and private-label workflows.
Why we ranked them here: Founded 2022 by Nathaniel Lambert and Zachary Hulecki. Temperature-controlled facility with three loading docks. Preps 100,000+ items per month for 100+ FBA customers. Pricing publicly disclosed: arbitrage $1.30 to $1.80/unit, wholesale and private label $1.00 to $1.30/unit, both tiered by volume. $299 sign-up for Tier 1-2, free for Tier 3 (2,000+ units/month). $500/month minimum invoice for accounts under 200 units/month. Storage free 14 days, then $0.50/cu ft/month. Also offers D2C fulfillment for non-Amazon channels (eBay, Walmart, TikTok) for multi-channel sellers; primary positioning is FBA prep. Slack-based 24/7 communication. Best fit for sellers above 200 units/month who want tax-free New Hampshire inventory storage and pricing certainty before committing.
Flagged: our most recent check could not reach this operator (website unreachable). Confirm directly before committing volume; see the profile for detail.
Family-run Hastings, Michigan prep center since 2022, leading with per-unit FBA prep from $1.10/unit; multi-service.
Why we ranked them here: A family-run Amazon FBA prep and fulfillment center in Hastings, Michigan, started by former Amazon sellers, operating since 2022. FBA prep is the lead, productized service with published per-unit pricing: $1.50/unit single, $2.25 multi-pack, volume tiers down to $1.10/unit, where the standard rate bundles receiving, inspection, polybags, FNSKU and expiration labels, bubble wrap, and outbound boxes. It also offers DTC pick-pack across 300+ channels, wholesale sticker-only freight, and LTL, so it is multi-service with FBA prep as the core. Best fit for sellers who want transparent per-unit prep with an all-in standard rate and multi-channel options.
Flagged: our most recent check could not reach this operator (website unreachable). Confirm directly before committing volume; see the profile for detail.
Ohio FBA prep and storage center operating since 2014, with a public per-unit prep rate card and pallet storage.
Why we ranked them here: An Ohio-based Amazon FBA prep and storage company serving experienced, volume FBA sellers, operating since 2014. It runs a published per-unit prep rate card covering labeling at $0.40, standard prep at $0.70, oversize at $0.95, inspection at $0.65, and kitting at $1.15, plus a pay-as-you-go per-unit option at $1.15 that includes inspection, labeling, bundling, and poly or bubble, alongside pallet storage at $15 per week. It works on a $350 monthly plan or a pay-as-you-go membership and does not accept online-arbitrage or online book resellers. Best fit for established volume sellers who want long-tenured prep plus storage under one roof.
We name names: both the candidates we excluded and the reason. The 3PLs we recommend separately (with outbound links) live on /fba-prep-3pl/.
Failed verification on integrity: no US facility behind a US-state-targeted page, and a cloned site carrying a false tax-free claim
Both had been machine-classified as pure FBA prep and failed only at the human 4-point review, which is why that review exists. FBA Prep at fba-prep.com is a real UK prep operator (Companies House-registered in Stoke-on-Trent) whose 'FBA prep services in Alabama' page is one of roughly 50 programmatic US state pages with no US facility behind any of them, plus stock-photo testimonials and footer link-farm injections; the Companies House entity behind it (no. 15590799) was incorporated on 24 March 2024 against a since-2017 experience claim on the site. Virginia Prep Center at virginiaprepcenter.com is a clone of prepcenterdelaware.com that still tells buyers it is 'sales tax free here in Delaware' while its only published warehouse address is in Herndon, Virginia, a state that charges sales tax, alongside contradictory pricing and placeholder blog content.
Failed our pure-FBA-prep classification test (3PL or fulfillment platform, not pure prep)
We imported amzprep.com's published 'Best 19 Amazon FBA Prep Centers' index as a candidate pool. 15 of them (including ShipBob, Ryder, Stord, DCL, Flowspace, ShipMonk, MyFBAPrep, eFulfillment Service, ShipHype, Simpl Fulfillment, AMZ Prep, YYZ Prep, Fulfillment-Box, Red Stag, Buske) primarily market themselves as 3PLs or fulfillment platforms with FBA prep as one offering among many. We list them as recommendations on /fba-prep-3pl/ instead.
FBA prep is one service line on a multi-channel 3PL or fulfillment homepage, not the core business
Re-screening 16 candidates that our classifier had left 'unclear', this time against each company's root homepage rather than the FBA sub-page the crawler discovered them on, confirmed 10 as multi-channel 3PLs: Staghler, KSP 3PL, Prep Partners Group, Full Prep Center, Midwest AWD, Launch Fulfillment, Foresmart, eHubSolutions, FLEX Fulfillment, and Coast to Coast Fulfillment. Each leads with general order fulfillment, warehousing, or freight across multiple sales channels, with Amazon FBA prep as one offering among many. They route to /fba-prep-3pl/ as recommendations, not directory listings.
Directories, an aggregator listing, an info blog, or a dead site, surfaced by keyword match but performing no prep
The same re-screen flagged 5 candidates that operate no prep facility: The Fulfillment Advisor (a 3PL and warehouse matchmaking directory), Prep Center Directory at prepcentersearch.com (a competing prep-center directory), a MapQuest auto-generated business listing, a Wyoming registered-agent and LLC-formation site whose only FBA mention is a blog post, and Catalist (whose domain now serves an unrelated outdoor-gear store, with the old FBA-prep page returning a 404).
FBA prep appears as a keyword or sub-page, but the core business is freight forwarding, multi-channel 3PL, marketing, or consumer package forwarding
A second root-homepage re-screen of 16 'unclear' candidates confirmed 12 more as not pure FBA prep: 3PL Bridge, Shipping and Handling, Excel3PL, Warehouse-Pro, Fulfillment CO, and Swifthouse are multi-channel 3PLs and fulfillment centers; Super International Shipping, Hongocean, USNA Warehouse, and Universal Shipping Inc are cross-border freight forwarders where shipping to Amazon is one line; Marknology is an Amazon PPC and marketing agency with a warehouse; and Boxette is a consumer package-forwarding platform. Each routes to /fba-prep-3pl/ or out of scope, not the directory.
Each change to the cohort is logged here with the date and reasoning, so anyone bookmarking or citing this page can see the state at a given time.
Added Urva Prep Center (Newark, Delaware), a multi-service FBA and Walmart WFS prep operation founded 2022, running a 25,000 sq ft tax-free facility at 301 Ruthar Drive plus a 10,000 sq ft site in Bear, with public volume-tier prep pricing from $0.70 down to $0.55/unit wholesale. It came in through our operator application and cleared the 4-point verification from primary sources. We confirmed the 301 Ruthar Drive address is distinct from the unrelated Newark prep cluster on Executive Drive and 310 Ruthar. The directory now spans 65 verified centers. Curation and honesty over volume.
Added 3 more verified centers from the discovery refill: EnZone PrepWorks (Conroe TX, dated public rate card from $1.20/unit, registry-confirmed owners), Live Free or Die Distribution (tax-free Rochester NH, NH SoS good standing, from $1.00/unit at volume), and Tailwind Pack & Ship (tax-free Billings MT, from $0.50/unit at volume, listed with a warning covering a 90-day inventory-forfeiture clause and a transit-liability disclaimer). The directory now spans 63 verified centers. Three candidates from the same pass were held rather than listed: a 6-month-old Louisville site with an apartment-street address and seeded testimonials, a Colorado operation whose current activity we could not confirm, and a Manchester UK company whose site has been frozen since 2021 with a broken contact link. We also published our UK ranking at /best-fba-prep-centres-uk/. Curation and honesty over volume.
Added 5 more verified centers after a root-homepage verification pass: Kitting & Assembly Solutions (Commerce City CO, since 2014, quote-based, 20 public Google reviews), FBAPrep4U (Gahanna OH, flat $0.90/unit wholesale-only), Montana Logistics Pro (tax-free Great Falls MT, public tiers $1.45 to $1.00/unit), Lulux Fulfillment (Long Island NY, 25% of each ASIN's FBA fee per unit, listed state-only because the operator withholds its street address), and Central Virginia Prep (Waynesboro VA, used-books specialty, listed with a warning for broken site navigation). The directory now spans 53 verified centers. Two candidates from the same pass were rejected: a UK operator running roughly 50 programmatic US state pages with no US facility, and a cloned site carrying a false tax-free claim for its Virginia address. One Brazil-facing hybrid is held pending identity questions. Curation and honesty over volume.
Added 4 more verified centers, promoted from the candidate universe after a root-homepage verification pass: Prep Center IN (Plainfield IN, tiered per-unit from $0.55/unit, no minimums), Simple Price Prep (St. Marys GA, family-owned since 2015, public per-service rate card), Oregon Prep and Ship (tax-free Sisters OR, since 2022, FBA plus 24-hour FBM), and Marketplace Prep (Fort Worth TX, since 2020, FBA prep productized down to $0.75/unit with public Trustpilot and Clutch reviews). The directory now spans 48 verified centers. Two candidates from the same pass were not listed: a clean prep-primary New Jersey operator under a year old (held until it crosses the 12-month bar), and a Philadelphia site that failed verification on fabrication (a 2026 domain claiming a 2018 founding, an address that maps to unrelated businesses, and recycled stock testimonials). Curation and honesty over volume.
Added 4 more verified centers, all leading with FBA prep: Rater Prep Services (Gahanna OH, public rate card from $1.00/unit), Simply Ship Now (Jacksonville FL, per-unit prep from $1.50/item plus disclosed done-for-you retail-arbitrage sourcing), Romex Enterprise (Cape Coral FL, an Amazon returns and removal-order reprocessing specialist since 2008), and Prep & Store Center (Ohio, prep plus storage since 2014). The directory now spans 44 verified centers. Several universe candidates were not listed this round: general fulfillment 3PLs whose Amazon-prep page is one of many service lines (routed out), a package-forwarding hybrid and two prep centers with no confirmable city (held for operator confirmation), and a stale low-volume site (held). Curation and honesty over volume.
Added 4 more verified centers, all promoted from the candidate universe: Boxy Prep (Hastings MI, from $1.10/unit), MI FBA Prep (Lapeer MI, since 2017, $0.85 to $0.90/unit), Ready Set Prep N Pack (tax-free Helena MT, $1.25/unit), and New Jersey Prep Center (Hainesport NJ, from $0.55/unit). Each leads with FBA prep and clears the operating, liveness, FDA-when-claimed, and manual-review checks. The directory now spans 40 verified centers across 20+ states; we continue to route general fulfillment 3PLs out and hold sub-12-month operators until they cross the track-record bar.
Added 4 more verified centers, all promoted from the candidate universe: AZ Prep Center (Tempe AZ, per-unit from $0.88), Kaizen Prep Services (Miami FL, since 2018, quote-based), DM Prep US (Libertyville IL, full rate card from $0.45/unit), and Cajun Prep (Kentwood LA, since 2020, $1.00/item, waitlist). Each leads with FBA prep. Several more universe candidates were not listed this round: general multi-channel fulfillment 3PLs where prep was a sub-service (routed out), and generic prep sites that never mention Amazon or FBA (held as unclear). The directory lists FBA-prep-primary operators with a real track record.
Added 4 more verified centers, all promoted from the candidate universe: FBA Champs (NJ, tiered from $0.45/unit), Priority Prep (Tyler TX, since 2017, 2-day guarantee), Esellts (Richmond VA, volume-tier down to $0.30/unit), and Flat Rate Prep (Madison WI, since 2016, one flat $2.25 all-inclusive rate). Each leads with real per-unit prep pricing as its primary offer. Several more universe candidates were not listed this round: general 3PLs and DTC-fulfillment houses where prep was a sub-service (routed to 3PL), and one clean prep center under a year old (held until it crosses the 12-month operating bar). The directory lists prep-primary operators with a real track record; everything else routes out or waits.
Added 4 more verified centers, all promoted from the candidate universe after primary-source verification: Number One Prep (Doral FL, per-unit from $0.45), Carolina Prep & Ship (Apex NC, family-owned, from $0.65), United States Prep (Salem NH, tax-free, $1.50/unit, flagged for an early-stage website), and Express Prep Center (Pennsauken NJ, from $0.65). Each leads with real per-unit prep pricing. Three more candidates were not listed this round: one whose website was returning errors, one general 3PL/freight forwarder with prep as a side line, and one ambiguous 3PL held for review. We list prep-primary operators and route pure 3PLs elsewhere.
Added 4 more verified centers: Dollan Prep Center (Newark DE, public rate card, with an honest below-average Trustpilot caveat), East Coast Prep and Ship (Wilmington DE, public rate card across FBA/WFS/SFP/DTC), 406 Premier Prep (Billings MT, public per-line-item card, no third-party reviews yet), and Brown Box Ninja (Temple TX, operating since 2014, tiered prep pricing). Two candidates were deliberately not listed: one whose own website was returning errors (fails the liveness check), and one general 3PL with no per-unit prep pricing held for editorial review. Curation over volume.
Added 4 more verified centers after primary-source verification against the 4-point standard: PrimeTime Prep (Portland OR plus Lincoln NE, public a-la-carte pricing), Proven Prep (Portland OR, 4.93/56 third-party rating), Stock and Ship (Springfield OR, BBB-confirmed since 2021), and Amazing Logistics (Sun Valley CA, operating since 2017). Proven Prep, Stock and Ship, and Amazing Logistics are multi-service operators published with disclosure; primary positioning is FBA prep in each case.
Added 8 verified centers after primary-source verification against the 4-point operator standard: Prep Ninjas (Oregon, family-owned since 2018), Grizzly Prep MT (Montana, third-party 5.0/5), HexPrep (Oregon plus Illinois, third-party 4.90/157), Extra Mile Prep (Alpharetta GA, 40,000 sq ft), Montana Prep Solutions (Helena MT, no fees or minimums), Oregon Prep Center (Portland OR, BBB A+), A&M Prep Services (South Gate CA), and Network Prep (Lafayette OR, currently waitlist-only). The phone-answered-live check was retired from the standard; verification now rests on registry/track-record, FDA-when-claimed, live-site-plus-FBA-keywords, and manual editor review.
Reframed as the dated 2026 ranking and published a companion verification study at /fba-prep-verification-study/ (what we found vetting the candidate universe, with named exclusions). Methodology copy corrected: placement is editorial, not a numeric weighted score.
Added 3 tax-free-state centers after primary-source verification: McKenzie Services (Oregon, women-owned, tiered membership pricing), Heroic Prep (New Hampshire, transparent per-unit volume tiering, 1,000-unit minimum), Delaware Prep & Fulfillment Center (Newark DE, multi-service FBA + FBM + arbitrage, operator-stated SPN). Cohort-2 source doc claims (founder names, capacity numbers, testimonials) were partially fabricated; everything in our published profiles was re-verified from operator-direct primary sources before listing.
Initial cohort published: 3 pure FBA prep centers (MyPrepCenter, WestFBA, FBA In and Out). 15 candidates from amzprep.com archived as non-pure-prep (3PLs or platforms); see exclusions below. More added weekly.

Comparing quotes? The FBA Prep Pricing Index 2026 aggregates the published rate cards behind this ranking: median US entry rate $1.30/unit across 44 verified centers (one duplicated rate card counted once), the tax-free-state premium, and the fixed fees the per-unit numbers hide.
