Inventory software has become expensive and bloated: hundreds of modules, per-user prices that punish small teams, and your data locked inside someone else's database. LightInventory takes the opposite approach. It runs on top of the Google Sheet you already use and adds everything a real inventory system needs, and nothing it doesn't: - Stock movements, transfers and counts - Approvals and roles scoped to locations - A tamper-evident history you can verify and revert - Detection of edits made directly in the sheet - Passkeys and MFA for every user, on every plan Your data never leaves your Google Sheet. If you stop using LightInventory, you keep the file and everything in it. Available in 27 languages.
