Why can't I enter purchases made on account at vendors via mobile app. Can only enter paid expenses via mobile app.. why?

It's nice to have you here, @ikpucool.

Right now, the option to create bills or purchases on account is not yet available in the mobile app. Having the option to use this feature would be a great addition.

Here at Intuit, we aim to understand better our customer's business needs within the software. This is why we welcome product suggestions to help improve our products and services. Changes in the program are released based on several factors, so we're unable to provide the turnaround time on when new features are released in QuickBooks. This info is controlled and handled mainly by the Developers Team.
