Upload a filled-in spreadsheet to bulk-add historical sales entries. Each row is validated individually, so one bad row won't block the rest — you'll get a full breakdown of what imported and what didn't.
Permanently deletes every sales entry in the system. A full backup is written to the server automatically before anything is deleted, but this cannot be undone from within the app — restoring afterward means manually reloading that backup file into the database.
Use this only when you're replacing the entire dataset with a fresh import (e.g. migrating from a new master spreadsheet), not for routine cleanup.
