It automates the whole Amazon/AliExpress-to-eBay workflow and tells you what it actually made you. A Chrome extension imports products in one click and can list them straight to eBay. Once you connect your eBay account, orders, fulfillment status and tracking numbers sync automatically. Supply prices and stock are monitored so you catch changes before they cost you. And on every order, ArbiKey applies the real eBay fee, shipping, VAT and today's exchange rate — so the profit figure is the one that survives contact with reality.

For automatic order sync, fulfillment tracking and one-click listing, yes — through eBay's own official login (OAuth), the same method every legitimate eBay tool uses. ArbiKey never sees your eBay password, and you can disconnect in one click at any time. The profit calculator and manual product tracking work even without a connection.

No. ArbiKey connects through eBay's official Developer API, the same program AutoDS, Sellbrite and every compliant eBay tool uses. It does not scrape your account, spoof your login, or do anything eBay's terms of service prohibit. Listing, syncing and tracking all happen through endpoints eBay built for exactly this purpose.

Yes. Import a product from Amazon or AliExpress with the Chrome extension, then list it to eBay in one click — title, price, category, item specifics and images are filled in automatically through eBay's official Listing API. You can also connect your existing eBay listings and let ArbiKey track and price them going forward.

Yes. Once a product is linked to its Amazon or AliExpress source, ArbiKey monitors the supply price and stock status in the background and flags changes — so a price increase or an out-of-stock item doesn't quietly turn a profitable listing into a loss.

Yes, and it is the fastest way to start. ArbiKey pulls your active eBay listings in through eBay's official API — title, price, quantity, SKU, image and listing link, in pages of 200. It only reads; nothing on eBay is changed. If your SKU field contains an Amazon ASIN, that link is picked up automatically. Afterwards a bulk screen opens so you can enter what each item cost you, because eBay will not tell us that and profit cannot be calculated without it.

Yes — title, price, quantity, SKU and your shipping, payment and return policies, all from ArbiKey without opening eBay. Your business policies are pulled from your own eBay account and picked per product. Two deliberate limits: quantity never goes below one, because writing zero to a listing can close it and end its sales history, and photos, description and category are out of scope because changing them can reset where the listing sits in eBay search.

Then ArbiKey shows you a dash, not a number. eBay never tells us what you paid your supplier, so for a product with no cost recorded there is no honest profit figure — and inventing one would quietly undermine the only thing this tool claims to do. Those products show no margin or ROI, and they are excluded from your totals and averages rather than counted as pure profit. The count of items missing a cost sits on your dashboard and filters to the list with one click, and costs can be entered in bulk.

For sellers whose main workflow is Amazon or AliExpress to eBay, yes. ArbiKey covers the same core automation as AutoDS — importing products, listing to eBay in one click, syncing orders and fulfillment automatically — while going further on the numbers: every order shows real net profit after eBay's exact category fee, shipping, VAT and the live ECB rate, not an estimate. If you need AutoDS's much broader multi-platform listing network beyond Amazon/AliExpress → eBay, the two can run side by side.

Spreadsheets are excellent until the exchange rate moves, eBay changes a fee, or you have 800 products across two stores — and they don't import products, list to eBay, or sync orders for you. ArbiKey automates the busywork and keeps the maths current at any size.

The catalogue has been tested past 9,000 products with search and pagination staying responsive. Free is limited to 30, Solo to 150, Seller to 600, and Scale is unlimited.

Rates come from the European Central Bank and are refreshed hourly on our server, so you are not depending on your browser reaching a third-party API. Cross-border maths — buy in one currency, get paid in another — is handled for you.

Your rows are isolated at the database level with row-level security, so no other account can read them. Every change is written to an append-only audit log. Backups are encrypted on Solo and above. And you can export everything to CSV, any time, no questions.

Yes, in one click, and you keep access until the end of the period you already paid for. Your data stays exportable. We do not hold it hostage to make cancelling awkward.
