Hi there, PDW.
It's a pleasure to see you here in the Community. I'm here to provide some information about turning off customer statement numbers in QuickBooks Online.
The option to turn off the customer statement numbers is currently unavailable in QuickBooks Online. I can see how these additional options and functionality would be helpful for both you and your business and I encourage you to submit feedback. These requests and suggestions are forwarded directly to our Product Development Team for consideration in future updates.
You can submit this within your QBO account by selecting the Gear icon and Feedback or by going to the following link: QuickBooks Online Feature Requests. Please know that I'm going to submit feedback from my side as well.
Also, you can always visit our Help Articles for QuickBooks Online in case you need some tips and related articles for your future tasks.
Let me know if you have any additional questions. I'll be one post away if you need help.
