My quickbooks online phone app closes itself down when i try to send an invoice🤷‍♂️

Let's troubleshoot your situation so you can continue sending your invoices using the app, Michael.
 

To verify, are you using the QuickBooks Online (QBO) mobile app through an Android or iOS device?
 

If you're attempting to send the invoice from an Android device, let's clear the app's data. An outdated application utility can impact the software's performance, and removing it could resolve common issues in its system.
 

Here's how:

1. Go to your device's Settings.
2. Navigate to Applications or Application Manager.
3. Select the QuickBooks Online app from the list.
4. Tap on Storage, then Clear Data.

Once you get the same result, I recommend updating the latest QBO app version from the Google Play Store. If the issue persists, you can also consider uninstalling and reinstalling it.

On the other hand, if you're trying to send the invoice from an iOS device, I suggest contacting our Live Support Team. They can dive into the root cause of your concern and provide a precise resolution by utilizing their specialized tools.

Alternatively, you can manage your invoices through the web version of QBO to continue billing your customers for every sale you've made.

You may also review the status of your invoices in the app. It can help you check which invoices are open, overdue, or paid.
