Edit or fix an extra before it is sent
Before an extra is sent to the customer, you can adjust it. After it has been sent, changes are tracked so the record stays honest.
While it is a draft
Open the extra from the Extras screen and edit the title or description directly. Nothing has been shown to the customer yet, so a draft correction is just an edit.
After it has been sent
The title and description are locked once an extra is sent -- there is no in-app edit for a typo caught after the fact today. Price changes are different: they go through a price revision, which preserves the full history and requires a fresh customer decision. OuttaScope never lets a price quietly change under an approval the customer already gave.
What happens next
For price changes specifically, see the price revision article -- it explains what happens to an approval link that is already out.
