Hello there, ClaudiaWest.

Let me start by saying how much I appreciate the time you spent to post your concern here in the Community. I want to help share what I know about the unique control number.

Right now, we don't have a specific turn around time yet as to when this will be available in QuickBooks Online. I'm on the process of sending feedback through our internal product enhancement list that we send to the product developers.

You can direct your clients' employees to our Chat Support for any questions related to the form (click the Live Chat option):

Thanks for coming to the Community. I wish you continued success in all you do.
