Pricely

Most bulk price tools report success when the API accepted the request. Pricely re-reads every variant afterwards and compares it to what you asked for. If any didn't take, the job is marked partial and names them, so you find out from the app, not from a customer. Before anything changes it snapshots the exact current price of every variant, so one click restores them precisely, not by re-applying a percentage in reverse. Scheduled sales auto-start and auto-revert in your store's timezone.
