Choosing the wrong 3PL for Amazon can cost you thousands in fees, delays, and lost sales. The right partner handles your FBA prep flawlessly while you focus on sourcing and scaling.
3PLGuys is an Amazon SPN-certified 3PL built specifically for Amazon sellers. We handle FBA prep with >99% accuracy, 24-hour turnaround, and the compliance expertise that keeps your shipments accepted and your account healthy. Here's what makes the best Amazon 3PLs stand out — and why sellers choose us.
Why Amazon Sellers Use a 3PL
Most Amazon sellers start by prepping inventory themselves. It works until it doesn't — usually around 500-1,000 units per month when the garage fills up and the labeling becomes a full-time job.
A 3PL for Amazon sellers handles:
- Receiving and inspection — checking shipments from suppliers for damage or discrepancies
- FBA prep — FNSKU labeling, polybagging, bundling, suffocation warnings
- Shipment creation — building compliant Amazon shipment plans
- Storage — holding inventory until you're ready to send it in
- Shipping to FBA — getting products into Amazon's network on schedule
What Makes a 3PL "Best" for Amazon?
1. Amazon SPN Certification
The Amazon Service Provider Network (SPN) is Amazon's vetted list of approved partners. SPN-certified 3PLs have proven they meet Amazon's standards for accuracy and compliance.
Why it matters: Fewer rejected shipments, fewer compliance issues, fewer headaches.
3PLGuys is Amazon SPN certified — Amazon has vetted and approved our FBA prep services. This certification means your shipments meet Amazon's strict requirements every time.
2. Location Near Ports or Fulfillment Centers
If you're importing from Asia, a 3PL near the ports of Los Angeles or Long Beach saves transit time and drayage costs. If you're shipping domestically, proximity to Amazon fulfillment centers reduces inbound shipping fees.
3PLGuys is located in Paramount, CA — minutes from the ports of Los Angeles and Long Beach. This makes us ideal for sellers importing from Asia or needing fast West Coast fulfillment.
3. Transparent Per-Unit Pricing
The best 3PLs for Amazon charge per unit, not mystery monthly fees. You should know exactly what labeling, polybagging, and storage cost before you commit.
Red flag: "Contact us for pricing" with no ballpark numbers anywhere.
4. Real-Time Inventory Visibility
You need to see your inventory levels, prep status, and shipment tracking in real time. A good WMS dashboard shows you:
- Units received vs. expected
- Prep progress by SKU
- Shipment status to Amazon
- Storage costs accruing
5. Fast Turnaround
Amazon's inventory limits and restock requirements mean timing matters. The best Amazon 3PLs turn around FBA prep in 24-48 hours, not 5-7 days.
3PLGuys offers 24-hour turnaround — your products are prepped and ready to ship to Amazon within one business day of receipt.
Common Mistakes When Choosing an Amazon 3PL
Choosing the cheapest option — Low per-unit fees often come with hidden costs: receiving fees, long-term storage fees, minimum volume requirements.
Ignoring location — A 3PL across the country adds days to your supply chain and increases shipping costs.
Not checking compliance experience — General warehouses often don't understand Amazon's specific requirements. One wrong label placement = rejected shipment.
