How to Start an Amazon FBA Business in 2026 (Complete Guide)

1. Why You're Reading This

You want to start an Amazon FBA business in 2026. You've watched 15 YouTube videos. They contradict each other. Half tell you it's saturated. Half tell you it's easier than ever. Most try to sell you a $1,997 course at the end.

I've been running this business full-time since 2018. My Amazon seller account did over $100,000 in revenue in May 2026. The 70 students in The Scaling Society did seven figures combined last quarter. This guide is the playbook I'd give my younger brother if he asked me how to start tomorrow.

It's long because the model has 30+ inputs and most beginner guides only cover 5. Read it once. Bookmark it. Reference it as you work.

"I'm going to share with you my game plan that I shared on stage at events. Amazon FBA, things are changing all the time. You have to actually succeed on Amazon FBA in 2026." Chris, How To Start & Scale Amazon FBA to $10k/month in 2025

2. What Amazon FBA Actually Is

Amazon FBA stands for Fulfillment by Amazon. You ship products into Amazon's warehouses. Amazon stores them, picks them, packs them, and ships them to the customer when an order comes in. You keep the profit after Amazon takes its referral fee and fulfillment fee.

You don't have to invent a product. You don't have to design packaging. You don't have to build a factory in China. You can if you want to. But you don't have to. Most of my students don't, and most of my own revenue comes from products other brands already made.

The business model has 4 main variants:

• Online arbitrage (OA): buy products from online retailers cheaper, sell on Amazon higher.
• Retail arbitrage (RA): same idea but you walk through brick-and-mortar stores.
• Wholesale: buy from authorized distributors at wholesale, sell on Amazon at retail.
• Private label (PL): manufacture your own branded product, list it on Amazon.

For 95 percent of beginners reading this in 2026, online arbitrage is the right starting model. Lowest capital. Fastest cash cycle. Doesn't require any supplier relationships. Scales to $10K/month before you need to graduate to anything else.

3. Is It Still Profitable in 2026? (The Honest Answer)

Yes. The model is harder for tourists and better for operators. Amazon fees went up twice in the last 18 months. IPI thresholds tightened. Brand restrictions got stricter. All three changes filtered out the lazy competition.

The real numbers: Amazon is still the largest US ecommerce platform at about 38 percent of total US ecommerce. Roughly $450 billion in annual GMV. 60 percent of that flows through third-party sellers. The catalog has 600 million ASINs. Profitable replenishables exist in the high six figures to low seven figures. You don't need a million. You need 30-60 active replenishable ASINs to hit $10K/month at typical ROIs.

I have a deeper breakdown in is Amazon FBA still profitable in 2026. The short version: if you have $1K+ of capital, 10+ hours a week, and the willingness to learn one new system, the answer is yes.

4. Step 1: Pick a Sourcing Model

Before you do anything else, pick your sourcing model. Each has a different capital requirement, time investment, and ceiling.

Online arbitrage: Start with $500-$1,500 of inventory budget. The lowest barrier to entry. The model I started with and still run.

Retail arbitrage: Lower upfront cash (buy 5 units at a time). Time-intensive. Doesn't scale past one person walking through stores. Hits a $3-5K monthly profit ceiling fast. OA vs RA detailed.

Wholesale: $5K+ to start meaningfully. Higher ceiling. Slower to enter because you need approved seller status with each brand.

Private label: $20K+ to do properly. 8-month ramp. Higher long-term margin but much harder execution.

Start with OA. Switch to or add wholesale around month 9-12. Skip PL until you're past $100K in OA revenue.

5. Step 2: Open Your Amazon Seller Account

Go to sellercentral.amazon.com. Sign up. You'll need: government ID, credit card, bank account, phone number, tax ID (SSN or EIN), and a utility bill for proof of address.

Pick the Professional plan ($39.99/month) not the Individual ($0/month plus $0.99 per unit). Individual sellers cannot win the Buy Box, and without the Buy Box you don't make consistent sales.

Identity verification now includes a live video call with an Amazon agent. The call is 5-10 minutes. Real person, real documents, and you'll pass first try.

Total setup time: 90 minutes plus 24-72 hours for verification. Step-by-step seller account setup.

6. Step 3: Decide Sole Proprietor or LLC

You can start as a sole proprietor (no paperwork, use your SSN, run business under your name) or form an LLC (paperwork, EIN, business bank account, asset protection).

For day one: sole proprietor unless you already have an LLC or you're certain you'll form one in 30 days. The LLC is paperwork. The business is sourcing. Don't let the LLC delay the business.

Once you're at $5K+ monthly profit, form the LLC. Wyoming, New Mexico, or your home state. $50-$300 in filing fees. LLC vs sole proprietor decision tree and EIN and business bank account setup.

7. Step 4: The Tool Stack

You need three tools to do this competently. Anyone telling you that you need more is upselling you. Anyone telling you that you need less is going to get you killed.

• Keepa (19 euros/month): price-history and sales-rank database. Non-negotiable. Keepa tutorial.
• RevSeller or SellerAmp ($20-30/month): Chrome extension overlaying live profit math on every Amazon page. RevSeller is what I show new students.
• Amazon Seller mobile app (free): scan barcodes in stores, check listings on the go.

Don't add a sourcing service or a $497 course for the first 60 days. Run those three tools, find your first 5-10 winners by hand, then layer in software once you understand what it's doing. Best OA software guide.

8. Step 5: Find Your First Product

The single best beginner sourcing exercise: pick one retailer (Kohl's, Macy's, JCPenney, or Boscov's are my four favorites because they all run aggressive coupon stacks). Go to their clearance section. Filter for items priced $15-$50 with a percentage-off coupon stacked on top of the sale price.

For each candidate, copy the product name, search it on Amazon, run the math in RevSeller. If your landed cost is at least 30 percent below the projected Amazon net, it's a buy.

The first product is the hardest. The tenth is easier. The hundredth is a habit. Plan 8-15 hours sourcing your first round of buys. After that the rhythm clicks and you can find a profitable lead in 20 minutes. How to find profitable OA products.

"Sourcing is actually easy if you stick to the basics. You just find products cheap that you can sell on Amazon higher. That's basically the whole business. You find products, you manage your margins, and you sell them for more money on Amazon." Chris, Simplifying the sourcing process for Amazon sellers

9. Step 6: Understand the Fees Before You Buy

Amazon's fees fall into three buckets: referral fee (percentage of sale, usually 15 percent), FBA fulfillment fee (flat per-unit, depends on size), and storage fee (per cubic foot per month). Plus newer fees: the Low Inventory Level Fee, inbound placement service fee, and Q4 storage surcharges.

Run every buy through RevSeller or the Amazon Revenue Calculator. Don't guess on fees. The fees are too variable per product. Every Amazon FBA fee for 2026 detailed and how to use the FBA calculator.

30 percent net ROI is my floor on every buy. 40-50 percent is the meat of my portfolio. Anything below 30 percent on projection is a no-buy.

10. Step 7: Read Keepa Properly

Keepa is the price-history database for Amazon. It tells you what an ASIN really sold for over the last 6, 12, and 24 months. Three habits separate winning sellers from losing ones:

1. Look at 90-day Buy Box average, not current price. Current price is a snapshot; 90-day average is reality.
2. Check the sales rank chart. A flat rank means no sales velocity. A bouncing rank means real sales. Use the "drops" to estimate units/month.
3. Watch FBA seller count. Climbing fast = price about to drop. Shrinking = window opening.

Full walkthrough in how to read Keepa graphs.

11. Step 8: Get Ungated in Profitable Categories

About 70 percent of the highest-ROI ASINs are in gated categories or restricted brands. Beauty, Toys, Grocery, Baby, top-tier brands across all categories. If you don't ungate, you're sourcing from the 30 percent of the catalog everyone else sources from. That's why "saturation" is mostly a self-imposed problem.

Four ungating methods that still work in 2026:

1. Auto-ungate (Amazon offers it on some categories if your metrics are clean).
2. Invoices from authorized distributors.
3. Brand authorization letters from manufacturers.
4. The Amazon-to-Amazon method (buying from business.amazon.com to use as your invoice).

Process 3-5 ungating applications a month proactively. Each one you win expands your sourcing pool by 5-15 percent. Get ungated on Amazon: the master guide.

12. Step 9: Decide Prep Center or DIY

A prep center is a third-party service that receives your products, inspects them, applies FBA labels, and ships to Amazon. They charge $1.30-$1.80 per unit. DIY at home is "free" except for your time, your tape, your boxes.

The hidden lever: prep centers in tax-free states (Delaware, New Hampshire, Montana, Oregon) save you the sales tax you'd otherwise pay shipping to your home address. That savings often covers the prep fee. Worth using a prep center from day 1 if you can. Prep center vs DIY prep breakdown.

13. Step 10: Create the Shipping Plan

The shipping plan is the Seller Central document that tells Amazon what you're sending, how many units, how it's packed, and which warehouse to send it to. The interface is from 2014 and trips up most beginners on their first try.

Workflow: Manage Inventory > Send/Replenish Inventory > pick packing type (Individual Products for OA) > enter quantities > pick FNSKU labels (always) > pick inbound placement option (run the math both ways) > print labels > enter box content (use 2D barcode upload to avoid manual processing fee) > print shipping labels > hand off to UPS or USPS.

14. Step 11: First Sale and the 14-Day Cash Gap

Your inventory hits Amazon. Listings go live within 24-72 hours. First sale usually within hours of going live if you priced competitively. Then Amazon takes 14 days to release the payout. This is the cash gap that breaks under-capitalized beginners.

Plan for it. Start with at least $500-$1,500 of capital you can leave in the business for 60 days without touching. Don't put your last $200 into inventory expecting the payout to land before your credit card statement closes. How much money to start Amazon FBA.

15. Step 12: Set Up a Repricer Early

A repricer automatically adjusts your listing price to win the Buy Box. Without one you'll either lose the Buy Box constantly or panic-match competitors into a loss.

Three repricers worth your time in 2026: Aura ($59/month), Bqool ($25-$50/month), SellerAmp Live ($30/month).

Critical setting: minimum price per ASIN below which you do NOT reprice. Set this to COG + all fees + 15 percent buffer. The repricer should never drop you below this floor. How to use an Amazon repricer.

16. Step 13: The 12 Mistakes to Skip

I keep a list of the mistakes I see kill beginners. The 12 most common:

1. Buying gated brands you can't sell.
2. Ignoring sales rank.
3. Pricing below cost on Buy Box races.
4. Skipping Keepa.
5. Quitting before payout cycle 3.
6. Not understanding FBA vs FBM.
7. Buying with Prime (it kills your seller account).
8. Mixing personal and business money.
9. Sourcing the same lanes everyone else sources.
10. Buying hazmat without realizing it.
11. Buying liquid in glass.
12. Not tracking units and costs.

Some mistakes are way harder to recover from than others and you absolutely need to avoid them." Chris, TOP 5 AMAZON FBA & ONLINE ARBITRAGE MISTAKES TO AVOID

17. What to Expect Month by Month

Realistic timeline I see across 70 students:

• Month 1: Setup. Seller Central, tools, first 5-10 buys. Spend money. No payouts.
• Month 2: First payouts. Break roughly even or net $100-$300 profit.
• Month 3: $300-$1,000 profit. Sourcing rhythm forming.
• Months 4-6: $1K-$3K monthly profit. You've identified your sourcing lanes.
• Months 7-9: $3K-$6K monthly profit. Replenishables compounding.
• Months 10-12: $5K-$10K monthly profit. This is where most plateau and decide whether to scale or stay solo.

Roughly 80 percent of TSS students who finish the first 90 days hit $5K monthly profit by month 9. The 20 percent who don't usually undercapitalized at the start or stopped sourcing because they thought they were "done."

18. Scaling Past $10K/Month

Once you're consistently doing $5K+ monthly profit, the next levers are:

• Hire a sourcing VA. Pay $4-$8/hour for someone to run your sourcing lanes. When to hire your first Amazon FBA VA.
• Add wholesale. Open accounts with 3-5 distributors. Higher volume, lower per-unit ROI.
• Optimize the repricer. Test 2-3 strategies on different ASIN cohorts.
• Manage IPI score. Liquidate slow movers monthly. Keep score above 600.
• Apply for inventory financing. Amazon Lending, Kickfurther, or business credit lines.

19. What I'd Do If I Started From Zero Today

If I had to start over tomorrow with $1,500 of starting capital and 12 hours a week:

1. Day 1-2: Open Seller Central, Professional plan, sole proprietor under my name.
2. Day 3-4: Subscribe Keepa and RevSeller. Watch Keepa's official tutorial. Read my Keepa post.
3. Day 5-7: Source 5-10 buys from Kohl's, Macy's, JCPenney clearance. 30 percent net ROI minimum.
4. Day 8: Place orders to a prep center in Delaware.
5. Day 12: Prep center processes, creates shipping plan, ships to Amazon.
6. Day 18-20: Inventory live on Amazon. First sales come in.
7. Day 30: First payout. Reinvest into next batch.
8. Day 60: Second batch live. Payout 2 hits.
9. Day 90: $300-$1,000 monthly profit. Sourcing rhythm established.

Total elapsed time from "want to start FBA" to "first $1K profit month": 90-120 days.

20. The Realistic Capital Math

Day 1 out-the-door costs for a realistic OA start:

• Amazon Professional seller plan: $39.99/month
• Keepa: ~$21/month
• RevSeller or SellerAmp: $20-30/month
• Starting inventory: $500-$1,000 minimum
• Prep costs: $50-$150
• Inbound shipping: $20-$50

Real day-one out-the-door: $700-$1,200. Under $500 is hard because you can't stay diversified enough across ASINs to survive normal variance. Full breakdown and how to start with $500.

21. The Honest Truth About This Business

Most people who try Amazon FBA quit. The model works. The execution requires patience, capital management, sourcing discipline, and the willingness to keep going when payouts haven't started yet. Most people don't have that combination.

If you do, the upside is real. I went from zero to six figures of annual revenue in 18 months. I'm now at $100K+/month. Of the 70 students in TSS, more than half have replaced their day-job income. A handful are running multi-six-figure operations.

None of them got there by reading guides. They got there by doing the work, week after week. This guide is the start. The actual business is the next 12 months of execution.
