No. That is exactly when the retention duty starts — and when the proof behind your margin would vanish.
No. The temptation to delete a row as soon as something sells is strong, but that is precisely the moment you need it: the purchase price and date are your evidence for the margin, and the retention period only starts running then. In France that is five years after closing, in Belgium ten years.
In practice this means sold should be a status, not a deletion. The piece leaves your shop window and your stock value, but the row stays, with the sale date and selling price added.
That is also what feeds your comparison register: purchase and sale side by side, per piece. Delete the sold rows and you rebuild that register from invoices every quarter.
Sources, each checked on 30 August 2026: article 60 of the Belgian VAT Code (extended from seven to ten years by the law of 20 November 2022), the Belastingdienst (Netherlands), service-public.gouv.fr (France) and gov.uk, VAT margin schemes — Keeping records (UK).

In Belgium ten years for your VAT records — extended from seven to ten by the law of 20 November 2022. In the Netherlands seven years, in France five years after the register is closed, and in the United Kingdom six years, and longer for as long as the piece is unsold.
Sold is a status, not a deletion. The piece disappears from the marketplace at once, but the row stays, with the purchase date, purchase price, sale date and selling price. That is exactly what you need to prove your margin, and it respects the retention period.
