I understand how frustrating it can be to toggle the custom transaction numbers on and off constantly, jb20147. 

I appreciate all the effort you have put into finding a way to turn off the custom transaction number in QuickBooks. However, this feature is integral to QuickBooks Online and cannot be turned off permanently. The custom transaction number is a unique identifier that helps to track transactions and eliminate the possibility of duplication. QuickBooks automatically generates it and cannot be modified or disabled. 

I want to share a workaround you can implement to achieve a similar result. You can turn off the custom transaction numbers by going to settings. 

1. Click the Gear icon, then choose Account and Settings.
2. Select Sales.
3. Under Sales form content, toggle off the Custom transaction numbers.
4. Tap Save and Done.
