we run a retail shop in central Strasbourg selling around 2,800 different SKUs across stationery office supplies and art/hobby items. btw for the past three years we've been tracking all stock movements, supplier orders and checkout sales manually using spreadsheets. it's just me and two employees working the store.
over the last few months our stock levels keep going negative. tbh whenever an employee makes a sale and forgets to deduct it from the sheet, an item physically on the shelf shows as out of stock on the sheet or the other way around. last week we accidentally double-ordered wholesale cases of the same erasers, tying up 800 EUR in cash needlessly.
i keep seeing open-source or cloud software offering "free inventory management," but part of me wonders if I should just optimize the Excel sheets with better formulas but i mean can free software handle this kind of volume, or is it time to bite the bullet and move to a paid commercal system?
