Sign Customiser has rebuilt the Adjust prices page so percentage-based bulk updates feel safer to use. Before you apply a change you can see exactly how the cheapest and most expensive options will move, and if you need to back out of a price change you can undo the last bulk update without restoring values by hand.

## What’s Changed

- **Live before-and-after preview** - Enter a percentage and instantly see how the cheapest and most expensive options in your customiser will change, including the per-£100 impact of the adjustment
- **Confirmation modal** - Review the full price range and the number of options affected in a confirmation dialog before any changes are saved
- **One-click undo** - Roll back the most recent bulk update from the same screen, with a clear note of who applied it and when
- **Safer rollbacks** - Sign Customiser detects when individual prices have been edited since the last bulk update and prevents the undo from quietly overwriting your manual changes
- **Accurate projections** - Previews use the same rounding rules as the saved price, so the numbers you see in the preview match the numbers your customers will see
