How Amazon → eBay dropshipping works (2026)
Selling without inventory: the flow, where the money goes, how to set a price, stock and price tracking, eBay and Amazon rules, risks, and a checklist before you start.
In this guide
In dropshipping you don't buy the item in advance. You list it on eBay; when it sells, you order it on Amazon to the buyer's address and upload the tracking number to eBay. The difference, after eBay fees and the Amazon cost, is your profit. This guide explains the flow, the money and the rules plainly.
1. The flow in six steps
- Find a product. Items with a stable Amazon price, in stock, and with demand on eBay. Brand and restricted-category checks are mandatory (rules).
- Eligibility check. VeRO (brand rights) list, blacklists, restricted categories, hazardous materials; never open a listing eBay will take down.
- List it. Title, photos, category, price. Price = Amazon cost + eBay fees + target profit; the Profit Calculator computes exactly that.
- When it sells, order on Amazon. To the buyer's address, as a gift (no price or invoice in the box), buyer's name and address.
- Upload tracking. A real tracking number the carrier can validate, within your handling time.
- Delivery and after. Questions, returns, cases; fast replies protect your defect rate.
2. Where the money goes: an example
You sold the item on eBay for $25 plus $5 buyer shipping; the buyer's state charges 7% sales tax. On Amazon you paid $15 plus 7% tax, shipping free with Prime.
| Line | Amount |
|---|---|
| Revenue you receive (25 + 5) | $30.00 |
| eBay final value fee (13.6% × $32.10 tax-inclusive base) | −$4.37 |
| eBay per-order fee | −$0.40 |
| Amazon supply (15 + 1.05 tax) | −$16.05 |
| Net profit | $9.18 |
| Margin (9.18 ÷ 30) | 30.6% |
| ROI (9.18 ÷ 16.05) | 57.2% |
Card cashback (for example Prime Visa 5%) lowers the cost by $0.75; ads or a return share reduce profit. Numbers use eBay.com's 2026 fee table.
3. How to set the price
- Break-even price: where profit is zero; selling below it is a loss. Fees change with price, so simple multiplication is not enough; the Break-even Finder solves it numerically.
- Target margin or target profit: "$5 per sale" makes more sense on cheap items, "15% margin" on expensive ones.
- Don't confuse markup with margin: buying at $15 and selling at $25 is a 67% markup, but the margin (profit ÷ revenue) after fees is about 30%.
- Competitor prices: you don't have to be the cheapest; handling time, return policy and seller rating also affect ranking.
4. Stock and price tracking
Amazon prices and stock change during the day. If the price rises your margin melts; if the item goes out of stock you can't fulfil the order, and a cancellation counts as a defect. So you need to scan Amazon regularly, recompute the eBay price (repricing) and end the listing when stock is gone. Watching a hundred listings by hand is not possible; that is the real job of automation.
5. Rules and risks, honestly
- eBay's dropshipping policy: eBay allows dropshipping where you fulfil orders directly from a wholesale supplier; buying from another retailer or marketplace that ships directly to your buyer is not allowed under its policy. Buying on Amazon and shipping to the buyer falls under that definition; your account health is your responsibility. How to reduce risk: real carrier tracking, handling time you actually meet, low cancellation and return rates, no invoice in the buyer's box.
- Amazon side: Prime membership terms prohibit using Prime shipping benefits for resale; use an Amazon Business account for commercial purchases and, where possible, a sales tax exemption (resale) certificate. Orders Amazon cancels or delays are your problem.
- Brands and VeRO: listings removed after a rights-owner complaint hurt your account; don't list brands that don't allow resale.
- Returns and INAD: in "not as described" cases the return shipping is on you; write accurate, simple descriptions instead of copying the Amazon page word for word.
- Tax: eBay collects and remits the buyer's sales tax; your own income tax and bookkeeping are a separate matter.
