Using MerchDash
Change history & rollback
Preview before you commit, and revert anything afterwards.
Every change MerchDash makes, from an automation run, a manual edit, or a bulk action, is recorded in Change history, grouped by the run that produced it. History spans all your enabled marketplaces, with a per-marketplace filter.
Preview before you commit
In the editor, Preview (dry-run) computes exactly which items a rule would change and why, without touching Amazon (see Preview & debug). Review-mode runs do the same: the changes wait in the queue for your approval.
Revert anything
Open any run to inspect each change, the item, the field, its before and after values, and the reason the rule attached with note(), then revert a single change or the whole run. Reverts are themselves logged as linked entries, so the trail is always complete; nothing is ever silently rewritten.

Undoing a whole run works through it one change at a time, restoring each value on Amazon and confirming it before moving on, so a run with thousands of changes takes a while. Revert run counts up as it goes (Reverting 240/2,000…) and keeps running even if you close the tab, press it again later and it re-attaches to the revert already in progress instead of starting a second one.
