Thank you for joining the thread @B-MUSIC-school,

I know how important it is, to disable the new feature of schedule payment. But, we don't have an option to disable the schedule payment feature once it's already in your QuickBooks Online account. Since this feature is the latest feature updates in QuickBooks Online.

You can visit this website QuickBooks Blog to check the latest product updates.

If you have anything else to ask about QuickBooks Online, just fill me in the comment section. I'm always here in the Community to help. Have a great day!
