About Business for Sale Listing Reader — Provenance Diligence
Open a business-for-sale listing on any site, in any language, and press the extension icon. The panel opens beside the listing and does one job: it puts that listing into the same twelve lines every time, so you can compare one shop with another without re-reading each page from scratch.
WHERE IT WORKS
The panel reads a listing on any website in the world. On 18 Spanish business-for-sale marketplaces we have checked against live listings, it starts with the page. On any other site it reads the page when you press the icon, and says plainly that we know that site less well, so check the numbers against the listing itself. Weekly watching of a listing on another site starts only after you allow access to that one site; the extension asks you in the panel. Sites whose terms forbid tracking listings are never watched.
WHAT A LISTING SHOULD ANSWER — TWELVE LINES
Legal name and tax number · address of the premises · owner or intermediary · price · rent · lease term and the right to transfer it · revenue and its period · profit and its period · documents behind those figures · staff · licences and permits · what is actually being sold.
Each line is either filled from the page, word for word, or it says plainly "not stated". Most listings answer two to six of the twelve. That is the point: the empty lines are the questions you would otherwise discover after paying a deposit.
A REQUEST TO THE SELLER, IN THEIR LANGUAGE
Press one button and the panel writes out the missing lines as a short, polite request — in your language, and again in the language of the page. You read it, you copy it, you send it yourself from your own account. We never write to sellers and never contact anyone on your behalf.
IN YOUR LANGUAGE
The panel speaks the language of your browser — 46 languages, from Spanish, German and Russian to Thai, Georgian, Persian and Chinese. Where your browser can translate on the device, the words of the page are translated too, with the original kept in a tooltip; where it cannot, the panel says so rather than pretending.
WHAT THE PAGE ITSELF SAYS
Below the twelve lines the panel quotes the marketplace: a struck-through previous price, the discount figure the site prints beside it, the date line — and it separates the day a listing was posted from the day it was pushed back to the top. Quotations, not our arithmetic. You can open "show everything the page says" to see every field the listing carries, exactly as written.
WHERE THE PRICE SITS
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 (so far, the listings on those 18 Spanish marketplaces; outside Spain the panel does not compare the price yet and says so). We never print a number we did not measure.
WHAT YOU KEEP
Save the listings you care about, from any business-for-sale site. Saving needs your Provenance Diligence account linked once: before offering to save, the extension checks the list kept there, so a listing you already saved on another device is never offered twice. Each saved listing keeps a dated snapshot of what the page said that day, marked "not checked against documents". If the page could not be read, the saved item is just the link, the title and the date. When you have sent your request, the saved card says so — and tells you when something new appears on that page afterwards. If a watched listing is taken down, the panel says that too, and your snapshot keeps what it said. Until you link an account, the extension makes no request to our server at all.
The panel belongs to the tab where you opened a listing. Leave that page and it switches off. It asks the seller nothing, gives no score and no traffic light, and never reads a page you did not open yourself.
