I run a small home goods and hardware store in Madrid. Right now, we actively have around 2,100 SKUs on our shelves and in storage. Up until now we tried tracking everything manually via spreadsheets, but as the business grew our physical register sales and the spreadsheet counts stopped matching up. btw when we did inventory last month we found a stock discrepancy of about 1,400 Euro; some items are sold out but show as in stock, while others are sitting on the shelf with zero record.
Switching to a system that integrates with a barcode scanner and updates in real time across the two shop computers has become an absolute necessity. When I search online, tons of free inventory tools pop up but most have a 100 or 500-item limit, or they cripple the barcode support. I don't want to commit to a 50-80 Euro monthly software subscription right off the bat.
Is there really a free or open-source solution that can smoothly handle 2,000 SKUs or should we just bite the bullet and go for paid software? What should I watch out for when migrating our data?
