Let me show you how it’s built.
Buy from a stranger, and for a moment you are just hoping.
Hoping they are who they say. Hoping it is theirs to sell. Hoping the money arrives.
Between two people, that doubt costs a bad purchase. Between two companies, weeks of lawyers. Across a border, often the whole deal.
Every deal waits on three answers.
First, who is on the other side.
Who are they?
Prove who you are once, and every service after that can check it. Each one sees only what it needs: that you are over 18, not your passport.
Then, what is really theirs.
Is it really theirs?
Sell a car, and its whole history goes with it: every owner, every service, every kilometre. Nobody can quietly change it.
Last, the money. Done.
Did the money arrive?
Agree the terms up front. When the parcel arrives, the seller is paid automatically. Nobody chases an invoice.
