With purchase prices on both sides. Do otherwise and you measure yourself rich.
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.
The number that comes out says how often you sell through your stock in a year. Two means a piece stays half a year on average; four means a quarter.
Measuring more often than quarterly rarely changes a decision. What does pay off is looking at turnover per category: it is usually a few groups dragging the average down.
Written on 9 September 2026. This answer describes a way of working, not a legal obligation: it contains no VAT rule, no rate and no deadline. What you must keep by law does differ per country — that is on the stock list page, with the source and check date per country.
This is an explanation, not tax or legal advice. Put your own situation to your accountant.
Most second-hand shops sit between 2 and 4. Above 4 is strong, but the right value depends heavily on your price range and the type of goods: expensive pieces stand longer, and rightly so. A very high turnover can also mean your shelves are too empty and you are missing sales.
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.
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.
