Pricing reflects published rates as of March 2026. Actual costs may vary based on volume, product type, and service complexity.

How we evaluated

We scored each prep center across five weighted criteria. Here is exactly how we arrived at our ratings.

Pricing Transparency

25%

Is pricing published on their website? Are there hidden fees for receiving, storage, or account minimums? We favored providers that list clear per-unit or per-service rates without requiring a sales call to get a quote.

Turnaround Speed

25%

How fast does inventory move from receiving to FBA-ready shipment? We measured standard turnaround (not rush or expedited) for typical prep tasks like labeling and poly bagging. 24-hour turnaround received the highest score.

Service Range

20%

Does the center offer the full spectrum of FBA prep services — FNSKU labeling, poly bagging, bundling, shrink wrapping, inspection, and carton packing? Providers that also handle returns processing, removals, or multi-channel fulfillment scored higher.

Technology & Integration

15%

Does the center provide a dashboard or portal for tracking inventory, shipments, and prep status? Can it integrate with Seller Central or other sales channels? Photo verification, barcode scanning, and real-time inventory counts were bonus criteria.

Customer Reviews

15%

We reviewed feedback across Trustpilot, G2, Reddit (r/FulfillmentByAmazon, r/AmazonSeller), and seller forums. We weighted recent reviews (2025-2026) more heavily than older feedback, and looked specifically for mentions of accuracy, communication, and issue resolution.

Detailed reviews

Each provider evaluated on pricing, services, strengths, and limitations.

1. Catalist

4.8/5

Best For

Wholesale sellers wanting sourcing + prep

Pricing

$0.40–$1.50/unit

Key Services

FNSKU labeling, poly bagging, shrink wrapping, bundling and kitting, carton packing, inspection and QC, wholesale sourcing from 1,200+ brands, ungating invoice support, daily Amazon FC delivery appointments.

Pros

  • Only prep center that also sources inventory — source and fulfill from one platform
  • 24-hour prep turnaround with daily Amazon FC appointments
  • Ungating-ready invoices included with wholesale orders
  • No minimum order quantities on sourcing

Cons

  • Single location in Brooklyn, NY — not ideal for West Coast sellers
  • Newer entrant compared to established prep-only companies
  • Wholesale focus may not suit pure private label sellers

Our Take

Catalist is the only provider on this list that combines product sourcing with FBA prep. If you sell wholesale products on Amazon, you can discover brands, place orders, and have everything prepped and shipped to FBA — without double-shipping through your own location. The trade-off is a single East Coast facility and a wholesale-centric catalog that will not appeal to private label sellers.

2. AMZ Prep

4.5/5

Best For

Global sellers needing international locations

Pricing

$0.50–$2.00/unit

Key Services

FNSKU labeling, poly bagging, bundling, inspection, removal processing, international forwarding, photo verification, multi-country prep locations (US, UK, Germany).

Pros

  • Multiple international prep locations for global marketplace selling
  • 24-48 hour turnaround on standard prep
  • Photo verification of every shipment before dispatch

Cons

  • Higher per-unit costs than US-only providers
  • Monthly minimum fees may apply for lower-volume accounts
  • Logistics-only — no sourcing or inventory procurement

Our Take

AMZ Prep is a solid choice for sellers who sell on Amazon US, UK, and EU marketplaces and want a single prep partner across all regions. Their photo verification adds a layer of accountability that many US-only centers do not offer. The premium pricing reflects the international logistics infrastructure.

3. ShipBob

4.3/5

Best For

DTC brands with multi-channel fulfillment

Pricing

$5.00+/order

Key Services

FBA prep, DTC fulfillment, Walmart WFS prep, B2B fulfillment, multi-warehouse distribution, Shopify/BigCommerce/WooCommerce integrations, 2-day express shipping, returns management.

Pros

  • 40+ fulfillment centers across US, Canada, Europe, and Australia
  • Strong technology platform with real-time analytics
  • Multi-channel fulfillment (Amazon, Shopify, Walmart, wholesale)
  • Same-day fulfillment on orders before cutoff

Cons

  • Significantly more expensive per-order than prep-focused centers
  • FBA prep is an add-on, not their core business
  • Overkill for Amazon-only sellers who do not need DTC fulfillment

Our Take

ShipBob is built for DTC brands that also sell on Amazon — not for Amazon-first sellers. If you run a Shopify store and use FBA as a secondary channel, ShipBob can fulfill both from a single inventory pool. For pure Amazon sellers, the per-order pricing model makes it one of the most expensive options on this list.

4. MyFBAPrep

4.2/5

Best For

High-volume sellers with complex prep needs

Pricing

$0.75–$2.50/unit

Key Services

FNSKU labeling, poly bagging, bundling, kitting, case packing, pallet building, inspection, returns processing, 50+ warehouse locations across the US, Seller Central integration via Preptopia platform.

Pros

  • Large warehouse network — 50+ locations for proximity to Amazon FCs
  • Handles complex kitting and subscription box assembly
  • Preptopia software for order management and tracking

Cons

  • 2-3 day standard turnaround is slower than competitors
  • Pricing is on the higher end, especially for simple prep tasks
  • Quality can vary between warehouse locations in the network

Our Take

MyFBAPrep is designed for high-volume sellers who need geographic coverage and complex prep capabilities. If you ship 10,000+ units per month and need locations near specific Amazon FCs to minimize inbound shipping costs, their network is hard to match. Smaller sellers will find the pricing steep for basic labeling and bagging.

5. Pattern

4.0/5

Best For

Enterprise brands needing marketplace management

Pricing

Custom pricing

Key Services

FBA prep and logistics, marketplace management (Amazon, Walmart, Target), listing optimization, advertising management, brand protection, data analytics, international expansion support.

Pros

  • Full-service marketplace management beyond just prep
  • Strong data and analytics platform for brand performance
  • Handles brand protection and MAP enforcement

Cons

  • No published pricing — requires enterprise sales engagement
  • Not designed for individual sellers or small businesses
  • Long onboarding timeline compared to prep-focused centers

Our Take

Pattern is not a traditional prep center — it is an end-to-end marketplace accelerator for established brands. If you are a brand doing $1M+ in annual marketplace revenue and want a partner to handle everything from listing optimization to logistics, Pattern is worth exploring. Individual Amazon sellers and small-volume operations are not the target customer.

6. eFulfillment Service

3.8/5

Best For

Small sellers wanting affordable prep

Pricing

$0.25–$1.00/unit

Key Services

FNSKU labeling, poly bagging, kitting, pick and pack, FBA shipment creation, returns handling, long-term storage, Shopify and Amazon integration.

Pros

  • Lowest per-unit pricing on this list
  • No monthly minimums — good for sellers just getting started
  • Over 20 years in business — established track record

Cons

  • 3-5 day turnaround is the slowest on this list
  • Single location in Michigan — limited geographic reach
  • Technology platform is basic compared to newer entrants

Our Take

eFulfillment Service is the budget option on this list. If you are a new seller shipping 50-500 units per month and cost is your primary concern, their low per-unit rates and no-minimum policy make it easy to get started. You trade speed for savings — 3-5 day turnaround means you need to plan shipments further in advance.

7. Buske Logistics

3.7/5

Best For

Midwest sellers wanting proximity to FCs

Pricing

$0.50–$1.50/unit

Key Services

FNSKU labeling, poly bagging, shrink wrapping, bundling, pallet building, freight shipping, FBA shipment creation, inspection, removal processing.

Pros

  • Midwest location near major Amazon FCs in Illinois and Indiana
  • 24-48 hour turnaround for standard prep
  • Competitive pricing for Midwest-based sellers

Cons

  • Regional operation — less useful for East or West Coast sellers
  • Smaller operation with less online presence and reviews

Our Take

Buske Logistics is a straightforward Midwest prep center with solid fundamentals. If your suppliers ship from the Midwest or you want proximity to Amazon's cluster of fulfillment centers in Illinois and Indiana, Buske can reduce your inbound shipping costs. Their smaller scale means more personal service but fewer online reviews to evaluate.

8. Beta Prep

3.5/5

Best For

NYC/regional sellers wanting local prep

Pricing

$0.60–$1.75/unit

Key Services

FNSKU labeling, poly bagging, bundling, shrink wrapping, inspection, carton packing, local pickup and delivery in the NYC metro area.

Pros

  • Local presence in the NYC metro area with pickup options
  • 24-hour turnaround on standard prep orders
  • Small-batch friendly — no large volume requirements

Cons

  • Regional-only — limited to the NYC metro and Northeast
  • Smaller operation with limited technology and reporting
  • Higher pricing relative to service scope compared to Catalist in the same area

Our Take

Beta Prep serves a niche: NYC-area Amazon sellers who want a local prep center they can visit in person, drop off inventory, or pick up returns. If that proximity matters to you, Beta Prep delivers. For sellers outside the Northeast, there are better options at lower price points.

How to choose a prep center

The right prep center depends on your business model, volume, and growth stage. Here is a decision framework by seller type.

Wholesale Sellers

Recommended: Catalist. If you sell wholesale brands on Amazon, Catalist lets you source products and have them prepped and shipped to FBA without double-shipping through your own location. The sourcing + prep integration saves time and money that no logistics-only provider can match.

Private Label Sellers

Recommended: AMZ Prep or MyFBAPrep. Private label sellers shipping from overseas manufacturers need a prep center that handles international receiving and custom packaging. AMZ Prep offers global locations; MyFBAPrep handles complex kitting and custom inserts.

DTC / Multi-Channel Brands

Recommended: ShipBob. If you sell through your own Shopify store, Amazon, Walmart, and wholesale channels, ShipBob can fulfill all channels from a single inventory pool across 40+ warehouses. Their per-order pricing is higher, but you avoid managing multiple fulfillment partners.

Enterprise Brands

Recommended: Pattern. Brands doing $1M+ in annual marketplace revenue that want a partner handling everything from listing optimization to fulfillment should evaluate Pattern. Their marketplace management capabilities go far beyond logistics.

Budget-Conscious Sellers

Recommended: eFulfillment Service. For sellers shipping fewer than 500 units per month where cost matters more than speed, eFulfillment Service offers the lowest per-unit rates with no monthly minimums. Expect 3-5 day turnaround.

High-Volume Sellers

Recommended: MyFBAPrep. Sellers shipping 10,000+ units per month benefit from MyFBAPrep's 50+ warehouse network. You can stage inventory at locations closest to your target Amazon FCs, cutting inbound shipping costs and transit times.

Do I need a prep center?

Amazon ended its in-house FBA Prep Service on January 1, 2026. Every seller now faces a choice: prep yourself or outsource it.

1

Compliance Risk Is Real

Amazon's Inbound Defect Fee is $1.74 per unit for non-compliant shipments — wrong labels, missing poly bags, oversized cartons, or incorrect suffocation warnings. At 500 units, that is $870 in penalties. Prep centers that do this full-time maintain 99%+ accuracy rates because their business depends on it. DIY sellers making occasional mistakes absorb costs that add up fast.

2

Time Is the Hidden Cost

A prep center processes your 500 units in 24 hours. Doing it yourself takes 15-20 hours of labeling, bagging, inspecting, packing, and scheduling shipments. That is 15-20 hours you are not sourcing new products, optimizing listings, or managing PPC campaigns. At any reasonable hourly rate, outsourcing prep is an investment in growth capacity, not just a logistics expense.

3

Cost Savings at Scale

Self-prep costs include a label printer ($200-$500), poly bags and supplies ($50-$100/month), workspace ($500-$2,000/month), and your labor. At 1,000 units per month and $1.00 per unit prep cost, you spend $1,000/month at a prep center — likely less than the combined cost of space, supplies, and 30-40 hours of manual labor. The math tips further in the prep center's favor as volume grows.

Frequently Asked Questions

What is the best Amazon prep center?
The best Amazon prep center depends on your business model. For wholesale sellers who want sourcing and prep under one roof, Catalist is a strong choice. For private label sellers needing international shipping, AMZ Prep is worth evaluating. For DTC brands selling on multiple channels, ShipBob offers the broadest fulfillment network. There is no single "best" — the right prep center matches your volume, product type, and growth stage.
How much do prep centers charge?
Most Amazon prep centers charge between $0.40 and $3.00 per unit for standard prep services. FNSKU labeling alone typically costs $0.15-$0.30 per unit. Poly bagging runs $0.15-$0.50 per unit. Bundling and kitting adds $0.50-$2.00 per bundle. Some centers charge flat monthly fees or per-order minimums. Always ask about receiving fees, storage costs, and minimum monthly commitments before signing up.
Do I need a prep center after Amazon stopped in-house prep?
Amazon ended its in-house FBA Prep Service on January 1, 2026. All sellers must now prep their own inventory or use a third-party prep center. If you ship more than 100 units per month, a prep center is almost always more cost-effective than self-prep when you factor in labor, supplies, space, and the risk of Inbound Defect Fees ($1.74 per unit for non-compliant shipments).
What should I look for in a prep center?
Focus on five criteria: pricing transparency (no hidden fees or surprise charges), turnaround speed (24-48 hours is the standard), accuracy rate (99%+ labeling and packing accuracy), technology integration (inventory tracking, photo verification, shipment updates), and location relative to Amazon fulfillment centers. Also check for monthly minimums, long-term contracts, and how they handle damaged or incorrect inventory.
Can a prep center source wholesale products for me?
Very few prep centers offer integrated sourcing. Catalist is one of the only providers that combines wholesale sourcing from 1,200+ brands with FBA prep and fulfillment. This eliminates double-shipping — inventory goes from the brand to the prep center to Amazon, rather than from the brand to you to the prep center to Amazon. Most other prep centers are logistics-only operations.
How long does FBA prep take?
Turnaround times vary by provider and order complexity. The fastest prep centers (Catalist, AMZ Prep, Beta Prep) offer 24-hour turnaround for standard prep. Mid-tier providers typically take 2-3 business days. Budget options may take 3-5 business days. Bundling, kitting, and custom packaging add 1-2 days to any provider's standard timeline. Always confirm turnaround expectations before your first shipment.
What is an FNSKU label and why do I need it?
An FNSKU (Fulfillment Network Stock Keeping Unit) is Amazon's internal barcode that ties a specific product to your seller account. Every unit sent to FBA must have an FNSKU label covering the manufacturer's UPC barcode. Without it, your inventory may be commingled with other sellers' stock — meaning customers could receive a different seller's product (potentially counterfeit or damaged) under your listing. FNSKU labeling costs $0.15-$0.30 per unit at most prep centers.
Is it cheaper to prep myself or use a prep center?
For most sellers shipping over 100 units per month, a prep center is cheaper than self-prep. DIY prep requires label printers ($200-$500), poly bags and supplies ($50-$100/month), workspace ($500-$2,000/month rent), and your time (valued at your hourly rate). At 500 units per month and $1.00 per unit prep cost, you spend $500/month — less than the combined cost of space, supplies, and 15-20 hours of labor. Self-prep makes financial sense only for very low volumes or very high-margin products.
Do prep centers handle bundling and kitting?
Most prep centers offer bundling and kitting as an add-on service, typically priced at $0.50-$2.00 per bundle depending on complexity. This includes assembling multi-packs, applying "Sold as Set" labels, shrink wrapping bundles, and creating virtual bundle listings. Not all centers handle complex kitting (e.g., subscription box assembly or custom inserts), so confirm capabilities before committing if bundling is a core part of your business.
How do I switch prep centers?
Switching prep centers takes 1-3 weeks and involves five steps: (1) Stop sending new inventory to your current center. (2) Have remaining inventory shipped to your new center or returned to you. (3) Set up your account with the new center, including Seller Central access and shipping preferences. (4) Send a test shipment of 50-100 units to verify accuracy and turnaround. (5) Redirect your regular shipments once the test passes. Watch for early termination fees or minimum commitment penalties with your current provider.
