Outcome. A key financial field edited on a deal after it closes won gets reverted to its closing value automatically and the change gets flagged for review, so a record that finance already acted on cannot silently drift after the fact.

When to use it, when not to
- UseUse it once
Amount,Close Date, or another field finance or ops relies on at close is at real risk of being edited after the fact, whether by mistake or to quietly adjust a number after invoicing. - UseRead this as what it actually is: a workflow cannot lock a record. HubSpot's real mechanism for restricting who can edit which properties is field-level permissions inside a permission set (Enterprise, Settings > Users & Teams > Permission Sets), which is the correct control if the goal is to stop most users from editing a field at all, permanently, not conditionally on deal stage. What this fiche adds is different and complementary: a detect-and-revert pattern that watches for edits specifically after Closed Won and reverses them, functioning as a soft lock for the small number of users, such as admins, whom a permission set cannot practically exclude.
- SkipDo not use this fiche as your only control if a hard, permanent restriction is what you actually need, build the permission set first, this fiche is the safety net for edits a permission set does not or cannot cover.
- SkipDo not use it on every deal property, pick a short list of fields that genuinely must not change post-close, locking everything makes correcting a real data-entry mistake after close needlessly painful.
