Hello, undeliverable.
As of this moment, creating purchase orders through QuickBooks App is not possible either on Android or iPhone. In the meantime, you can create purchase orders through the web browser and desktop app. I can see how important and beneficial it's to you and our other valued customers.
I'll make sure to gather the information here and tap this to our developer's team. This way, creating purchase orders through the QuickBooks app might be given a chance to be included in the next product updates. You can also visit the article for more information about the list of available features for the mobile app: QuickBooks Online mobile app feature comparison.
In the meantime, you may want to consider visiting our QuickBooks Blog. From there, you can see the future developments and the latest news about QuickBooks and what our Product Care Team is working on.
You can also visit this resource hub: Mobile Applications Hub. It contains topics about installing the mobile app, fixing login issues, running reports, and updating your billing information.
Let me know if there's anything else that I can help you with. You got me covered! Stay safe!
