Is there any free inventory management software?

Yes, free inventory management software exists in three honest flavors: free tiers of paid products (usually capped at low order counts, single user, or limited channels — fine for testing, tight quickly), open-source software like Odoo Community (genuinely free and capable, but you host, configure and maintain it yourself — the cost is your time), and spreadsheets (free forever, with the well-known accuracy ceiling).

What 'free' rarely includes: sales channel integrations that stay reliable, barcode scanning, multi-user audit trails, and support when something breaks at 5pm on a Friday — which is roughly the list of things that stop stockouts and oversells.

VNDLY isn't free — plans start at $49/month — so the honest framing is: free options are real, and if your volume is small, use one. The paid product earns its fee when order volume makes errors expensive.
