Where a business-for-sale listing sits against a market we counted. Nothing leaves your browser unless you link your account. Open the page of a business for sale — on any site, in any country — and press the extension icon. The panel opens beside the listing and prints what the page actually says: the asking price with its currency, rent and turnover if stated, the trade, the city; and what the listing leaves out — the things a buyer normally learns only after paying a deposit. On Spanish marketplaces the panel also shows where the price sits among comparable listings and how long the listing has really stood, against a market we counted ourselves. On other marketplaces it says so plainly: "we have not counted this marketplace yet". We never print a number we did not measure. Save the listings you care about. Your list stays in your browser. If you choose to link your Provenance Diligence account, saved listings appear in your account as well, and the extension can report what it sees on the listings you saved — and nothing else. It asks the seller nothing, gives no score and no traffic light, and never reads a page you did not open yourself.
