Detailed Reviews

Urva Prep Center

FTL Consolidation Prep for FBA, WFS, FBM, DTC, and Two-Step Dropshipping

Newark, Delaware

Urva has been running FBA prep for over four years out of their Newark, Delaware warehouse. What separates them from most prep centers is their FTL consolidation model. Rather than sending your inventory via SPD like everyone else, they consolidate shipments across clients into full truckloads, which means Amazon checks your inventory in within 24 to 48 hours instead of the 2 to 3 weeks you'd wait with standard parcel shipments. If you've ever had capital sitting in transit for weeks, you know how much that costs you.

They also use industrial shrink wrap machines instead of polybags, which speeds up processing and gives every unit a cleaner, retail-ready finish. No suffocation warning labels required either.

Beyond FBA and WFS prep, they handle FBM and DTC fulfillment with direct integrations into Amazon, Walmart, and Shopify, so orders sync automatically without any manual work on your end. They also run a dedicated two-step dropshipping workflow with same-day reshipping, supplier branding removed, and orders reboxed under your label.

Strengths

✓FTL consolidation gets inventory into Amazon in 24 to 48 hours vs. 2 to 3 weeks for SPD
✓Inbound shipping at $0.20 to $0.50 per lb
✓Industrial shrink wrap machines, not polybags
✓FBA and WFS prep, FBM and DTC fulfillment, and two-step dropshipping all under one roof
✓Direct integrations with Amazon, Walmart, and Shopify
✓First 14 days of storage free, then $0.02 per unit per day
✓Located in Delaware, zero sales tax

Limitations

✗FTL consolidation requires at least a full pallet of non-hazmat / non-oversized inventory
✗Single warehouse location

Pricing

• FBA & WFS Prep (Wholesale & Private Label): $0.55/unit flat, including FNSKU labeling and unit protection
• FBA & WFS Prep (Online Arbitrage): $1.50/unit flat, including FNSKU labeling and unit protection
• FBM & DTC Fulfillment: $2.50/order + $0.50 per additional unit in the same order
• No setup, software, or receiving fees; $300 monthly minimum

Verdict: The best overall option for Amazon and Walmart sellers who want faster check-ins, lower inbound costs, and a prep center that does more than labeling. The FTL model alone saves clients millions in inbound shipping every year.

PrepVia

Automation-First Prep with a 35-Hour End-to-End SLA

Medley, Florida

PrepVia runs an automated prep operation out of Miami-Dade with one standout feature: a 35-hour end-to-end SLA guarantee, meaning if they miss it, prep is free. They process labels at 13,200 units per hour and are one of only 63 Amazon SPN certified providers nationwide.

Verdict: A strong pick for Florida-based sellers who want speed accountability. The SLA guarantee is one of the better commitments in the industry, though it covers prep only and not the full inbound journey.

MyFBAPrep

The Largest Warehouse Network for High-Volume Sellers

50+ warehouses across the US, UK, and EU

MyFBAPrep operates at a scale most prep centers can't touch, with over 85 million square feet of warehouse space globally. If you're an enterprise brand that needs distributed inventory across multiple regions, this is the most obvious choice.

Strengths

✓50+ warehouse locations globally
✓Multi-channel fulfillment across Amazon, Walmart, and Shopify
✓Container receiving at port locations
✓Strong option for enterprise-level volume

Limitations

✗Quality is inconsistent across locations
✗No public SLA guarantee
✗Pricing varies by warehouse and can be hard to predict
✗Communication depends on which location handles your shipment

Verdict: Best for large brands that need national or international coverage. Smaller sellers will likely find the experience inconsistent and the pricing harder to manage.

AMZ Prep

Canadian-Based Prep with US and International Operations

Montreal, Toronto, Shenzhen, New Jersey

AMZ Prep has built its reputation serving Canadian sellers entering the US market, with a location in China for importers who need a near-source option.

Strengths

✓International network across Canada, the US, and China
✓Strong cross-border logistics experience
✓Photo verification on all shipments

Limitations

✗Limited US presence with only one location in New Jersey
✗No documented API or tech-driven workflows
✗US-only sellers have stronger domestic alternatives

Verdict: The go-to for Canadian sellers and importers from China. If you're based in the US and selling domestically, there are better options.

ZonPrep

Southeast-Focused Prep with Regional Coverage

Georgia, Tennessee, New Jersey

ZonPrep runs three warehouse locations with a focus on Southeast Amazon fulfillment centers and a stated 48-hour prep SLA.

Strengths

✓Three warehouse locations for regional coverage
✓48-hour prep SLA
✓Handles both FBM and FBA workflows

Limitations

✗SLA covers prep time only, not end-to-end
✗No documented automation or throughput metrics
✗Limited public reviews

Verdict: A reasonable regional option for sellers in the Southeast. Lacks the technology and transparency of more established competitors.

ShipBob

DTC-First Fulfillment with FBA as a Secondary Service

40+ fulfillment centers globally

ShipBob is built for direct-to-consumer brands first. Their Amazon FBA prep is an add-on, not a core offering, which shows in how the service is structured.

Strengths

✓40+ fulfillment centers worldwide
✓Strong integrations with Shopify, BigCommerce, and WooCommerce
✓Advanced analytics dashboard
✓2-day express shipping program

Limitations

✗FBA prep is not their main focus
✗Pricing has multiple fee layers that add up
✗Minimum order requirements on some services
✗Not ideal for Amazon-first sellers

Verdict: A good fit for brands where DTC is the priority and Amazon is secondary. If Amazon is your main channel, look elsewhere.

✓Experience with international sellers
✓Container receiving for imports

Limitations

✗Primary expertise is in the UK market, not the US
✗Limited US warehouse presence
✗Cross-timezone communication can be slow

Verdict: Best for UK and EU sellers expanding into Amazon US. American sellers already operating domestically have better options available.

ShipMonk

✓Handles FBA, FBM, and DTC fulfillment

Limitations

✗Widespread customer complaints about billing disputes

Strengths

✓Competitive per-unit pricing

Limitations

✗Limited capacity for sellers growing quickly

Verdict: Fine for getting started. Most sellers outgrow it within a few months once volume picks up.

How to Choose the Right Prep Center

SPD vs. FTL Inbound Shipping

Standard parcel shipments take 2 to 3 weeks to check in at Amazon. Full truckload consolidated shipments check in within 24 to 48 hours and typically cost significantly less per pound. If you're sending meaningful volume, the difference in cash flow is substantial.

Unit Protection Method

Polybags over a certain size require Amazon suffocation warning labels. Shrink wrap skips this requirement entirely, processes faster, and produces a cleaner finished unit.

Prep Time vs. End-to-End Time

Most prep centers advertise how fast they work on your inventory once it's in their hands. The number you should care about is how long it takes from your inventory arriving at the warehouse to it being available for sale on Amazon. Ask about the full timeline, not just the prep window.

Pricing Tiers

Per-unit costs drop significantly at higher volumes. Get a full breakdown of every tier before committing, and make sure you understand what is and isn't included in the base price.

Location and Placement Fees

West Coast prep centers tend to come with higher Amazon placement fees and longer transit times to major fulfillment centers in the Southeast. Delaware hits a good middle ground for most sellers.

Sales Tax

States like Pennsylvania and California charge 6 to 8% sales tax on prep services. Delaware charges none. Over a year of volume, that adds up.

Peak Season Capacity

Ask your prep center directly how they handle Q4. A center that runs lean all year may not have the staff or space to handle 3 to 5 times the normal volume once the holiday rush hits.
