¿Cómo Vender en Amazon y Ganar Dinero en 2026? | CURSO Gratis de Amazon FBA

Core thesis

Amazon FBA (Fulfillment by Amazon) is an accessible, scalable e‑commerce vehicle for reselling (arbitrage) and later wholesale/scale. For beginners it’s the fastest, lowest‑risk path compared with private label. Success depends primarily on buying well (sourcing/procurement and product selection) and leveraging Amazon’s traffic and logistics — the seller’s core skill is product sourcing and analysis, not marketing or listing creation.

Business models explained

Fulfillment by Amazon (FBA)

• Seller sends inventory to Amazon warehouses.
• Amazon handles storage, pick/pack, shipping and customer service.
• Recommended for scale and “sleep‑time” sales.

Fulfilled by Merchant (FBM)

• Seller handles shipping and customer service.
• Scalable but operationally heavier; not recommended for beginners.

Arbitrage

• Online arbitrage / Retail arbitrage: buy discounted or retail goods (online or in‑store) and resell on Amazon for a markup.
• Low initial capital; a practical training ground to learn product analysis.

Wholesale

• Buy direct from brands/distributors at scale.
• Requires higher investment and relationship work (calls / email).
• Very scalable once margins and account maturity are established.

Private label

• Create your own brand and product.
• High barriers to entry (time, capital, product development).
• Recommended later, after mastering arbitrage/wholesale.

Frameworks, playbooks and processes

Product‑selection checklist (5 core criteria)

1. High and stable demand (consistent ranking / monthly unit sales).
2. Price / ticket size preferably > ~$15 (so unit economics are meaningful).
3. Healthy number of competing sellers (3–4+ FBA sellers is comfortable).
4. Stable price history (no heavy downward volatility).
5. You can source at a price that leaves acceptable margin / ROI after Amazon fees and fulfillment.

“Buy, send to FBA, let Amazon do logistics” playbook

• Validate demand and pricing with tools.
• Buy a small test batch.
• Ship to FBA (prep and inbound).
• Monitor sales and returns.
• Reinvest profits and scale toward wholesale.

Other processes

• “Fail fast and cheap”: start with small buys and validate before scaling.
• Account strategy: begin with a single seller account; at larger volumes use separate legal entities/accounts for operational and risk control.
• Capital strategy: use OPM (other people’s money — banks, credit, investors) after validating repeatable profitability.
• Team & systems: standardize sourcing, inbound prep and supplier relationships; hire product researchers and delegate execution as volume grows.

Tools, processes and tooling playbook

Key tools mentioned

• Keepa (referred to as “Kipa”): historical price, Buy Box trends, ranking charts — confirm price stability, seasonality, vendor counts and sales velocity.
• Repseller (green box): daily/30‑day unit estimates, seller counts (FBA vs FBM), average third‑party price, fee breakdown per sale — helps compute margins/ROI quickly.
• “Smart” (market intelligence): brand/seller revenue estimates and mapping of major sellers — see brand‑level sales and top third‑party sellers.
• ScanProfit (Scan Profit / vendor scouting Chrome extension): locates products across retail sites (Costco, Walmart, Chewy, etc.) to compute arbitrage opportunities and generate leads.
• Seller Central: operational backend for orders, inventory, finance and returns.

Typical operating tooling cost ballpark

• Amazon Professional seller plan: $39.99 / month.
• Repseller tool: ≈ $9 / month.
• Market‑intelligence tools (e.g., “Smart”): ≈ $100 / month (varies).
• Presenter’s baseline estimate for a small reselling operation: ~ $150 / month (tools + Amazon subscription).

Key metrics, KPIs and example calculations

Market and seller metrics used for decisions

• Units/month (demand estimate).
• Number of FBA sellers.
• Buy Box ownership.
• Historical low price and price stability.
• Best Seller Rank movements.

Representative market figures and brand examples

• Amazon.com buyer pool cited at ~310 million people with buying intent.
• Bath & Body Works (brand): ≈ $6M/month on Amazon; a single candle product example ≈ $111k/month with ~68 sellers (43 FBA sellers).
• Logitech: ≈ $35M/month on Amazon; about 75% sold by Amazon, ~25% (~$7M) by third‑party sellers.
• Expo markers: >20,000 units/month — example of very high velocity, low‑price SKUs.

Representative unit economics

• Example A: sell price $33.99, cost $20 → seller net after fees $27.45 → profit ≈ $7.45 → ROI ≈ 37%.
• Example B (lead): buy at $44.10, sell at $68.50 → profit ≈ $7.12/unit → at ~55 units/month → ~$395/month profit from that product.
• Small account examples used to illustrate scale: one account sold $27,000 in one day; another reached $931,000 in a period.

Actionable, repeatable recommendations

Starter checklist (step sequence)

1. Choose business model: start with resale/arbitrage and FBA.
2. Open an Amazon Seller account (use a dedicated email).
3. Use tools (Keepa, Repseller, ScanProfit or equivalents) to analyze demand, price history, seller counts, fees and ROI.
4. Source a small test quantity from retail, online, or supplier leads.
5. Send to Amazon FBA (prep and ship).
6. Monitor sales, profitability and inventory turnover; reinvest profits and scale to wholesale.

Product selection guidance

• Prefer everyday consumer goods (non‑seasonal).
• Favor higher velocity items with per‑unit price > ~$15.
• Target listings with a manageable number of FBA competitors (3–5 ideal).
• Verify historical lowest price is above your break‑even threshold; keep cushion for price competition.
• Avoid private label and complex imports until you understand Amazon and have capital.

Sourcing tactics

• Start with retail/online arbitrage (Costco, Walmart, Chewy, regional events like Black Friday).
• Use sourcing software to scan inventories and identify arbitrage opportunities.
• After validation, contact distributors and brands for wholesale purchases (phone/email outreach).

Risk and operational practices

• Start small to validate product and process.
• Track margins and ROI, not just revenue.
• Account for all fees (referral, fulfillment, storage) and inbound prep costs.
• When scaling, separate accounts/entities for risk management and accounting clarity.
• Systematize and document processes; hire remote analysts or buyers for execution.

Concrete examples / mini case studies

• Bath & Body Works candle: ~ $111k/month; many sellers — example of how many resellers can capture parts of brand demand.
• Logitech mouse: ~2,000 units/month; few FBA sellers; stable price (~$130) — potential to compete if you can source cheaply.
• Expo markers: extremely high velocity (20k units/month) — tradeoff: big turnover but low per‑unit margin.
• Small arbitrage lead: buy at $44.10, sell at $68.50 → ~$7.12 profit/unit → capturing 55 units/month → ~$395/month — illustrates recurring cash from a single validated lead.

Operational & leadership tactics

• Treat the seller account as a real business from day one (dedicated email, bookkeeping).
• Focus founders on decision‑level skills: what to buy, supplier negotiation, and scaling strategy.
• Build simple systems and delegate daily tasks (remote analysts, buyers) as you scale.
• Use OPM and credit after validating a repeatable, profitable process.
• Emphasize data‑driven decisions: “Don’t be the buyer—become the seller.”

Costs and economics to plan for

• Amazon Pro seller subscription: $39.99/month.
• Research tools: from ~$9/month (basic) to $100+/month (market intelligence).
• Typical baseline tooling + subscription: ≈ $150/month for a small operation.
• Amazon fees: referral fee % varies by category; fulfillment fees apply.
• Capital: arbitrage can start with tens or hundreds USD; private label typically requires much larger upfront capital.

Common mistakes to avoid

• Starting with private label / China imports before mastering sourcing.
• Falling in love with a product and ignoring data (price history, rank, supply).
• Starting too large without validation — don’t scale before testing.
• Ignoring seasonality.
• Underestimating Amazon fees and logistics costs.

Closing operational checklist (concise)

1. Decide model: FBA resale/arbitrage.
2. Create seller account (separate email).
3. Install/subscribe to research tools (Keepa, Repseller, ScanProfit or similar).
4. Apply product selection criteria (demand, price >$15, several FBA sellers, stable price/rank, achievable sourcing price).
5. Buy small test inventory → send to FBA → monitor performance → reinvest & scale.
6. Build supplier relationships and transition to wholesale when ready.
7. Systematize operations, hire, and track profit (not just revenue).
