Check a product's estimated demand — eBay's estimated units sold, observed active-listing prices and competition.
Explore a category by estimated demand — product types ranked by an estimated market gap based on official eBay signals.
1. Product research
It's the most important tool. It lets you see demand (reviews, sales), prices, competition and trend for any product. Without it, you're choosing blind. A good research tool scores each product and tells you whether it's worth it or not.
2. Supplier analysis
Finding the product is half the job; the other half is sourcing it reliably. You need to evaluate suppliers by Trade Assurance, MOQ, certifications and reputation so you don't lose your investment to defective orders.
3. Margin (FBA profitability) calculator
The selling price isn't your profit. A margin calculator subtracts Amazon fees, product cost, shipping and storage to show your real net margin. (Read our guide on how to calculate your real Amazon FBA margin.)

All in one platform: Soldnova
Soldnova is not trying to replace the full Amazon suites: it does one thing they either charge a lot for or simply estimate, and it does it with official data. Using the official eBay API it gives you, for any search, eBay's own estimated units sold (cumulative), the best-selling listing with its price, the observed price range of active listings (median and P25–P75) and how many listings compete. On top of that: a catalog of 7,000+ observed listings from eBay and Amazon with their current price, an explorer that breaks a category into product types ranked by market gap, and direct sourcing links to Alibaba, AliExpress, 1688 and DHgate. Sales figures are eBay estimates, not an exact count: they are for comparing products and ruling out the ones nobody buys, not for projecting your revenue. You can try it without an account in the free tool. And there is a free plan to start.
