We run a small-scale auto spare parts sales and distribution business in Bologna. We currently actively track around 450 SKUs in our warehouse. We are a team of three, and ever since we started out, we've been trying to keep track of all incoming and outgoing items, shelf numbers, and costs using shared Excel spreadsheets.
Over the last few months, though, things have started getting seriously messy. Whenever two people open the file at the same time, sync errors pop up, and one person can accidentally overwrite stock quantities entered by the other. At least once or twice a week, an item that shows as in stock can't be physically found on the shelf, or a product in the warehouse doesn't show up in the system at all. It leaves us in a really tough spot with our clients.
When I looked up "free inventory management software" online, I came across a few freeware and open-source options. Should we just enforce stricter formulas in Excel and soldier on, switch to one of these free tools, or bite the bullet and invest in paid professional software? I'm worried about grinding daily operations to a halt while migrating the data.
