Spot it
Tell Tradzi how much you've got to flip, and it finds the stock. Or check something you've seen on a marketplace, at a car boot or on a shop shelf.
For resellers and side hustlers
Find the flip before anyone else.
Tell Tradzi your budget and it finds stock worth flipping, what to pay, how many to buy and where to sell each one. Spotted something on Facebook Marketplace, Vinted or in a charity shop? It checks that too.
Free to start: 5 checks a month, no card needed. Not ready? Try the demo, no sign-up.

Questions
Where do the prices come from?
Amazon price and sales history from Keepa, prices you check yourself, and (switching on soon) live eBay listings through eBay's official API. Vinted prices are used with Vinted's permission; Tradzi never collects data from Facebook. For Facebook listings, you share the listing and Tradzi does the maths. More about our data.
Is it always right?
No tool can promise what something will sell for. Tradzi shows a confidence score and where every number came from, and holds back its verdict when the data is thin.
Do I need to be a business?
No. Choose Personal or Business in settings and Tradzi uses the right fees, including VAT if you're registered.
Can I cancel?
Yes, any time from your account. You keep your plan until the end of the month you've paid for.
