Finding discounted products online and selling them at a higher price on another marketplace is one of the business models used in e-commerce. Widely known among Amazon sellers, this method is called online arbitrage.
What Is Amazon Online Arbitrage?
Online arbitrage is buying a product at a good price from an online sales channel and reselling it at a higher price on a different platform, in this case Amazon. The seller’s profit is the difference between the purchase cost and the Amazon sale price, after fees.
How Does Amazon Online Arbitrage Work?
The online arbitrage process has many steps, from finding the product to receiving the sales revenue in your account:
- Find a product that is cheap enough at an online store.
- Check that the product is listed on Amazon and that you are allowed to sell it.
- Calculate profit after all costs.
- Buy the product.
- Check, prepare and list or ship the product (FBA or FBM).
- Customers buy on Amazon.
- Amazon pays out the revenue after fees.
Online Arbitrage vs. Retail Arbitrage, Dropshipping and Wholesale
- Retail arbitrage means buying products from physical stores; online arbitrage sources them from online stores.
- Online arbitrage and dropshipping are not the same business model. In online arbitrage the seller mostly buys the product first and holds stock; in dropshipping the seller does not hold stock and the supplier ships to the customer.
- Wholesale: Products are usually bought in large quantities from the brand, manufacturer or authorized distributor. Online arbitrage buys from retail sources in smaller quantities.
Is Amazon Online Arbitrage Legal?
Buying a product legally and reselling it is possible in many countries. But the product’s authenticity, the condition used, compliance with brand rules, Amazon policies, tax obligations and consumer rights must all be respected. Whether you need a company, tax registration and invoicing depends on the seller’s country, the Amazon store they sell in and the scale of commercial activity; get advice from an accountant in your country.
What Do You Need to Do Online Arbitrage?
Opening an Amazon account is not enough on its own. You need product research, sourcing, finance, document keeping and inventory management.
Opening a seller account: Business and identity information must be prepared. The requested information varies by marketplace.
How to find online arbitrage products: Online arbitrage product research compares the purchase price at online stores with selling opportunities on Amazon. Review discount pages, check brands’ official sites, match products to the Amazon catalog and use the Amazon Seller app.
What to check in product research: A low purchase price does not make a product profitable. Look at:
- Whether you are allowed to sell the product
- The Amazon sale price
- The number of sellers
- Whether Amazon itself sells it
- Sales rank
- Price history
- Reviews and ratings
- Product size and weight
- Return risk
How Is Profit Calculated?
When calculating profitability, all costs must be included. The basic formula: profit = Amazon sale price − purchase cost − Amazon fees (referral, fulfillment, storage) − shipping and prep costs − taxes.
- ROI shows how much profit the product capital produces: ROI = net profit ÷ product cost × 100.
- Net profit vs. profit margin: Net profit is the money left from the sale; profit margin is net profit divided by the sale price.
Many sellers also keep a reserve for returns and price drops.
FBA vs. FBM
FBA stands for “Fulfillment by Amazon”: the seller sends the products to Amazon warehouses, and after an order Amazon picks, packs and ships and handles customer service for the shipment. FBM is the method in which the seller prepares and ships the orders to the customer: the seller holds stock, packs and ships.
| Criterion | FBA | FBM |
|---|---|---|
| Storage | Amazon | Seller |
| Packing | Amazon | Seller |
| Shipping | Amazon | Seller |
| Fees | Fulfillment and storage fees | Your own shipping costs |
| Control | Less | More |
Sending products to FBA: After the products arrive from the online store, do not send them to the Amazon warehouse without inspecting them. Check the products, remove old labels, add the Amazon barcode, follow packaging rules and create the shipment plan. A prep center is a service that receives, checks, labels, packs and sends your products to the Amazon warehouse.
Why Do Invoices Matter in Amazon Online Arbitrage?
One of the most critical risks of the online arbitrage model is sourcing documents. Amazon may ask for documentation to verify the authenticity or sourcing of a product. A retail receipt is not always enough; keep invoices that show the supplier, the product, the quantity and the date.
Brand and category restrictions. Amazon can require prior approval for some products, brands and categories (sellers call these “gated” products). Check your selling permission before you buy stock.
Keeping the product authentic and in the right condition. Source only original products from reputable suppliers, and list the product under the correct condition: a product sold as new must be unused, complete and in original packaging.
Key Amazon Concepts
- ASIN: The unique ID Amazon gives to products in its catalog. Several sellers can offer the same product on one ASIN.
- Featured Offer: Commonly known in the past as the Buy Box, the offer shown in the “Add to Cart” and “Buy Now” area of the product page. Winning it greatly affects sales.
- Price war: When sellers on the same product keep undercutting each other. Chasing the lowest price can destroy your margin.
- Inventory management: It is not always right to buy a lot of the most profitable-looking product. Online arbitrage opportunities can be short-lived. Buy quantities you can sell within a reasonable time.
- Seasonal products: Toys, decoration, gift sets and seasonal products sell more at certain times of the year.
Advantages and Disadvantages
Advantages: No product development needed, you can start with a small quantity, it can be run from home, existing product pages are used, different categories can be tested and it can scale with FBA.
Disadvantages: Supply continuity can be weak, there is a document risk, price competition is high, brand complaints can occur, stock can be left unsold, there is an account health risk and it needs continuous product research.
What Are the Risks of Amazon Online Arbitrage?
- Being unable to sell the product
- Price drops
- Retailer order cancellations
- Account suspension
- Currency risk
- Tax risk
- Return risk
- Storage risk
Common Mistakes
- Buying products without checking selling permission
- Looking only at the sale price
- Not checking price history
- Matching the product to the wrong ASIN
- Treating a receipt as an invoice
- Buying too much stock
- Not checking the product’s condition
- Constantly lowering prices to win the Featured Offer
- Neglecting tax and accounting
- Not setting aside a reserve for returns
A Sample Business Plan
| Stage | Work to do |
|---|---|
| Market selection | Choose the Amazon country to sell in |
| Account setup | Open and verify the seller account |
| Legal and tax setup | Company, tax and invoicing as required |
| Product research | Find and calculate opportunities |
| Purchase and prep | Buy, check, label and send products |
| Listing and pricing | Monitor offers and prices |
| Reporting | Track profit, ROI and stock turnover |
Managing capital: Do not put all the starting capital into product purchases. Keep a share for fees, returns and unexpected costs.
Online arbitrage vs. private label: In online arbitrage you sell existing branded products, while in private label you sell your own brand, which gives more control but needs product development. Businesses can also set up their own online store alongside Amazon, which gives more control over customer data and brand.
