What ArbiKey does that AutoDS doesn't
Common questions
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. Many AutoDS users add ArbiKey specifically for this reason.
