Add up the purchase prices, not the asking prices. That is the figure everyone asks for.
Add up what you paid for the pieces still standing. Not your asking prices: those are an expectation, not a value. You need that figure for your year-end accounts, and it is also the denominator of your stock turnover.

That is why recording the purchase price per piece is not an administrative burden but the foundation: without that figure per piece there is no stock value, no turnover ratio and no margin.

For a second-hand business this number says more than turnover. It is the money sitting on your shelves today instead of in your account — and therefore also what you free up by tackling your dead stock.
Divide the purchase value of what you sold in a period by the average purchase value of your stock over that same period. Use purchase prices on both sides: dividing selling prices by stock valued at cost makes your turnover artificially high. Calculating once a quarter is enough for most businesses.
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, so keep them until well after the sale. In the UK six years, in Belgium seven; in France ten years for an electronic register, from each entry (R321-6-1), and five years for a paper register, from its closing (R321-6).
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.
