ArbiKey vs AutoDS
for Amazon → eBay Arbitrage
Both tools import products and automate your eBay listings and order sync. The real difference is what happens next: ArbiKey shows the exact net profit on every order, after every fee. Here's exactly how they differ — and why serious sellers use both.
Both platforms automate importing, listing and order sync for Amazon/AliExpress-to-eBay sellers. AutoDS covers a much broader range of platforms and suppliers. ArbiKey is focused specifically on eBay and pairs that automation with real net profit after every eBay fee, VAT, shipping cost and live exchange rate — the number AutoDS doesn't calculate. Many sellers run both.

Where ArbiKey goes further
Common questions
Does ArbiKey also automate eBay listing like AutoDS?
Yes. ArbiKey's Chrome extension imports products from Amazon or AliExpress and lists them to eBay in one click through eBay's official Listing API, then keeps orders and fulfillment status in sync automatically via a secure eBay connection. AutoDS covers a wider range of platforms and suppliers beyond eBay; ArbiKey is focused specifically on the Amazon/AliExpress-to-eBay workflow and pairs it with real net-profit tracking.
Can I use ArbiKey and AutoDS together?
Yes — and many sellers do. AutoDS handles operational work (listing, repricing, orders). ArbiKey handles financial intelligence (real net profit, fee breakdown, FX rates). They don't overlap in functionality.
Does AutoDS show real profit after eBay fees?
AutoDS shows estimated profitability using approximate fee rates. It doesn't apply live exchange rates or the exact category-specific rate eBay charges — including the often-missed fee on the shipping portion of the sale.
Is ArbiKey cheaper than AutoDS?
ArbiKey starts free (30 products, no card required) and paid plans start at $9.99/month. AutoDS starts from around $14.99/month with no free tier. They solve different problems, so it's less about cost and more about which gap you need to fill.
I use AutoDS — do I need ArbiKey too?
If you want to know your real net profit per product (not just sales volume), then yes. AutoDS tells you what sold. ArbiKey tells you what you kept after every fee, tax and exchange rate — while also handling your own eBay listing and order-sync automation. Many AutoDS users add ArbiKey specifically for the profit visibility.
