Amazon FBA Guide: if you’re thinking about selling on Amazon, you probably have questions—lots of them. From what to sell, to how to ship, to the fees that quietly eat your margin, the learning curve can feel steep. In my experience, the levers that separate a floundering listing from a steady seller are simple: smart product research, clean listings, and measured reinvestment. This guide covers Fulfillment by Amazon (Amazon FBA) end-to-end—practical steps, realistic costs, and the pitfalls I’ve seen new sellers stumble over. Read on and you’ll come away with a working roadmap you can act on this week.
What is Amazon FBA (Fulfillment by Amazon)?
Amazon FBA means Amazon stores, packs, and ships your products, and handles customer service and returns. Sellers send inventory to Amazon fulfillment centers, and Amazon handles the rest. That convenience often drives higher conversion and Prime eligibility, but it comes with fees and rules you must understand.
Why choose Amazon FBA? (Pros & Cons)
Short version: FBA buys you time and scale, but it costs money. From what I’ve seen, FBA is best for sellers who want to scale quickly, leverage Prime, and avoid logistics headaches.
Benefits
- Prime eligibility: boosts conversions and trust.
- Hands-off fulfillment: frees time for marketing and sourcing.
- Customer service handled: returns and support managed by Amazon.
Drawbacks
- FBA fees: storage, fulfillment, and optional long-term storage fees apply.
- Less control: returns and damaged inventory rules can be strict.
- Complex inventory rules: prep, labeling, and shipment plans require care.
FBA vs FBM: Quick Comparison
| Feature | FBA | FBM (Fulfilled by Merchant) |
|---|---|---|
| Shipping & Returns | Handled by Amazon | Handled by seller |
| Prime | Yes | Usually no |
| Fees | Higher (storage, fulfillment) | Lower per-order fees, but shipping costs vary |
| Control | Less control over inventory | More control over packaging/customers |
Step-by-step: Launching with Amazon FBA
1. Choose a product (product research)
Good product research is the backbone. Look for items with steady demand, reasonable competition, and room for margin after FBA fees and ads. Use best sellers lists, keyword tools, and real-world observation. I often start by scanning the top 100 in a niche and looking for products with simple improvements (better bundle, higher-quality material, clearer photos).
2. Decide your model: private label, wholesale, or retail arbitrage
- Private label: build your own brand—higher margin, more work.
- Wholesale: buy established brands in bulk—simpler to start but lower margins.
- Retail arbitrage: flip discounted retail items—fast testing but not scalable long-term.
3. Sourcing and samples
Test samples from multiple suppliers before committing. Negotiate minimum order quantities and request clear packing instructions that match Amazon’s prep requirements.
4. Calculate profitability
Always run the numbers. Include cost of goods, shipping to Amazon, FBA fees, referral fees, and expected ad spend. Aim for at least a 30% margin after all costs when starting out.
5. Create a high-converting listing
- Keyword-rich title (use top search terms).
- Five bullet points highlighting benefits and use cases.
- Clear, professional images (show scale and usage).
- Optimized backend search terms.
6. Prepare and send inventory to Amazon
Follow Amazon’s FBA shipment workflow: create a shipment plan, label units (or opt-in for Amazon labeling for a fee), and ship to the designated fulfillment center. Mistakes here cause delays and extra charges.
7. Launch strategy and Amazon PPC
Start with a mix of sponsored product ads and targeted manual campaigns. I usually set modest bids, gather data, and then scale what converts. Promotions and early reviews (compliant with Amazon policies) help with the initial sales velocity.
8. Monitor metrics
Track sessions, conversion rate, ACOS (advertising cost of sales), and inventory days of supply. These tell you whether the product needs price adjustments, ad optimization, or restocking.
Common pitfalls and how to avoid them
- Ignoring packaging and prep: non-compliant units can be refused or charged prep fees.
- Underestimating fees: use Amazon’s FBA calculator for accurate fee estimates.
- Poor keyword strategy: no traffic means no sales even with a beautiful listing.
- Overstocking: long-term storage fees kill profits—forecast demand carefully.
Scaling your FBA business
Once you have one product doing well, rinse and repeat: optimize the listing, expand variations or bundles, and introduce complementary products. Consider moving some best-sellers into multi-channel fulfillment or using virtual assistants for listing and PPC tasks.
Real-world example
I worked with a seller who launched a kitchen gadget as a private label product. They focused on improving image clarity and adding a bonus recipe card. After optimizing the title and running targeted Amazon PPC for two weeks, conversion climbed from 1.2% to 6.3%—and monthly revenue doubled. Small, cheap improvements often compound quickly.
