Deleting a scheduled price change before it has been processed will prevent it from running and updating your professional stock. If the scheduled price change has already happened, you will not be able to delete it or roll back the changes.
From the SalonBridge dashboard, click on 'My Business' and then on 'Professional Stock':
Click on 'Professional Stock Options' and then on 'Schedule Price Update':
On the top of the screen, click on the 'Pending Professional Stock Price Updates' tab:
Find the professional stock update you wish to delete and click on the trash icon on its corresponding row.
Once deleted, the scheduled update will not be run on the date and time it was scheduled for.
