Why can’t I send or create invoices on my phone anymore

I understand that you are concerned about creating an invoice and accessing the customer tab in your mobile app, @mike-jmj. I would like to provide some insight into why this might be happening.

The QuickBooks system may occasionally display unusual behavior as a result of synchronization or latency issues. To troubleshoot these errors, clearing the application's data can be an effective solution. Here are the steps to take:

For iOS:
 

1. In Settings, click General.
2. From the iPhone Storage, select QuickBooks Online app. 
3. If done, choose Offload App. 

For Android:

1. From Menu, tap More options ⋮.
2. Hit Settings and Refresh Data. 
3. After that, select Yes to confirm. 

Furthermore, I recommend checking out this article to understand the features supported by each device in QuickBooks Online: Compare mobile app features.

Thank you but I think something is up cause nothing is populating in my app on Phone or desktop I’m not sure why 

I’m not sure what is happening nothing is populating in my Mobil app or desktop 

I appreciate you getting back to us and performing the troubleshooting steps shared by my colleague, mike-jmj. 

I'm here to ensure we resolve this. I'll provide additional steps to fix the issue of nothing populating on both your mobile device and desktop.

Before proceeding, may I know the operating system of your phone? Is it iOS or Android? It'll help us determine why nothing is appearing on your screen. Can you also share what data isn't showing in the mobile app or desktop? Is it the invoice and customer page only? Or all the QuickBooks menus? Sharing a screenshot would be a great help, too.

If you're using an iOS version, we've received similar cases or reports about the issue. I recommend contacting our support so they can add you to the affected list. To do so, please follow the steps in this article. It also includes a direct phone line to speak with a representative: QuickBooks Online Support.

In case you have an Android version, ensure it runs on a supported operating system. The problem could be due to a compatibility issue. I've listed the requirements (iOS and Android) below:

• For Apple products, your device should be iOS 11.1 or newer.
• For Android products, your device should be Nougat 7.1.1 or newer.

If the Android device is supported, I suggest uninstalling and re-installing the app to rectify this. It could be an update issue. Setting up the updated app on your phone rectifies this issue. 

In the meantime, you can log in to your QuickBooks Online account via a browser. Beforehand, make sure you're using the supported one to avoid problems when creating and sending invoices.

Additionally, I've added these two articles (for mobile and browser) to help you receive and record invoice payments once your customers pay you. Select the resource that you need when tracking the fund:

• Record invoice payments in QuickBooks Online (browser)
• Receive an invoice payment using the QuickBooks Online (mobile app)

Keep me updated if you have additional concerns or questions about creating or sending your invoices. This way, I'll be able to provide the assistance you need in keeping your sales record accurate.
