Fleeta CatalogGuard: Prices

CatalogGuard keeps its own snapshot of your catalogue and tells you when something changed for the worse: a price under cost, a compare-at price that no longer shows a saving, a product hidden or out of stock, a lost image or variant. Every alert shows the old value and where to restore it. Changes made by other apps can be muted so they are recorded but raise no alert, and notifications are throttled so a bulk import sends one message. Read-only. Built in the UK by Fleeta, free right now.
