A small downloadable browser tool for recording stock and entered sales at a stall or event. Add inventory, record a sale, Undo mistakes, export a CSV report, and save or restore a full JSON backup.

You receive a ZIP containing the standalone HTML tool, instructions and fictional CSV examples. Extract it and open the HTML in your browser; no app account or installation is required. One-time purchase, not a subscription.

Read before buying: use one browser and one tab. Browser storage can disappear or fail; export and independently verify JSON backups and keep separate records. CSV cannot restore an event. If all storage writes fail, an old saved tally can reappear after reload without a new warning. Sales value is quantity sold times listed price, not verified money received, profit or accounting revenue. No payment collection, integrations, cloud backup or multi-user synchronization.

Early version. Owner-reported backup/export/restore checks and automated logic tests passed; this is not independent certification of every browser or device. Start with the examples and verify your inputs and results.
