The Complete Guide to FBA Prep Services: What Amazon Sellers Need to Know

If you sell on Amazon, you already know this: FBA (Fulfilled by Amazon) gives you reach, speed, and credibility.

But what most sellers don’t realize is that the key to winning with FBA isn’t just having a great product—it’s prepping your inventory correctly.

In this guide, we’ll walk you through everything you need to know about FBA prep services—what they are, why they matter, and how to choose the right partner to keep your Amazon account in good standing and your profits protected.

What Is FBA Prep?

FBA prep refers to all the steps your inventory must go through before being sent to Amazon’s fulfillment centers.

Amazon has strict requirements. Miss one label, bundle, or polybag—and your inventory could be rejected, delayed, or even disposed of.

FBA prep includes:

• Labeling (FNSKU, expiration dates, warning labels)

• Polybagging (for loose items, hygiene protection, suffocation compliance)

• Bubble wrapping (for fragile or sharp items)

• Bundling or kitting (multiple units sold as one)

• Inserting instructions, coupons, or inserts

• Packaging to Amazon box and weight standards

• Palletizing and shrink-wrapping for LTL freight

Amazon won’t do any of this for you. And if you don’t follow their guidelines to the letter, you risk delays, chargebacks, or account penalties.

Why Amazon Sellers Shouldn’t Do Prep In-House

It’s tempting to handle prep yourself, especially when you’re just starting out. But here’s what most sellers discover:

🚨 It’s time-consuming

Stickering 1,000 units by hand is fine once. Doing it every week while managing PPC, listings, and customer service? Not scalable.

😵‍💫 It’s error-prone

One mislabeled item can get your entire shipment rejected or flagged.

🧾 It’s more expensive than you think

When you factor in labor, space, materials, and the opportunity cost of your time—outsourcing becomes a smart move.

🧍 You become the bottleneck

You can’t grow if you’re stuck taping boxes in your garage every day.
