Then your margin cannot be established — and that is exactly the amount you pay VAT on.
Then applying the margin scheme correctly becomes difficult or impossible. The scheme taxes the difference between purchase and sale; without a purchase price there is no margin to tax and you fall back on the normal rules: VAT on the full selling price. In the UK, HMRC says so in as many words.
A missing purchase price throws no error. You notice it at the moment you need it, and by then the piece is usually gone.
For pieces already in stock the late but real answer is: write down what you still know — where it came from, when it arrived, roughly what you paid — and put it to your accountant. For every new purchase: the note is written at the buying, not at the selling.

This is an explanation, not tax or legal advice. Put your own situation to your accountant.
The purchase date, a description that identifies the piece, the price you paid, and the seller's details. In the Netherlands the opkopersregister expressly asks for a private seller's details; in France the livre de police asks for surname, first name and address, plus the method of payment.
The record-keeping duty in none of the four countries asks for a photo: what is asked is a description, the date, the price and the seller. But with unique pieces a description in words is rarely enough to find one among three hundred — and that is exactly what an inspection or a customer question asks you to do.
Vintro Pro keeps, per piece, what you paid, when, and where it came from. Your stock list and your margin VAT build themselves while you work.
