Thanks for coming back in the Community, @nicofars.

There is no specific time frame when this billable feature will be available on the mobile app version. I know how this feature is important to your business.

For now, I suggest visiting our QuickBooks Blog website to stay up to date new features and latest update.

You can check out this article for future reference about helpful articles in QuickBooks: Help articles for QuickBooks Online.

Fill me in if you have other questions or concerns about QuickBooks. I'm always here to help.
