Everytime I try to attach a PDF invoice to an Expense I get the following error message “attachment upload fail” This error message has started in the last month.

Hello there, info1734.

I'll help you figure this out so you can get back to business.

You'll want to update the QuickBooks mobile app to the latest version. Here's how:

1. On your device, open the App Store.
2. Select the Today tab, then select your profile.
3. In the Available updates section, look for the QuickBooks mobile app.
4. If you see the option, select Update.

Once done, try uploading your attachment to see if you can successfully upload it without any error. However, if you get the same results, you can perform other troubleshooting steps by clearing your app's cache. 

Here are the steps:

1. Go to the Help menu.
2. Select Reset App Data.
3. Click OK.

Also, I'm adding an article that you can visit about managing receipts in QuickBooks Online for reference: Attachments in QuickBooks Online.

Please feel free to get back to me with any additional questions about attachments, @info1734. I've got your back.

Sorry, none of this has worked. Im

still getting the same error

Hello, info1734. 

Since updating and resetting the app didn't work. We can uninstall and reinstall the application to start in a clean slate. 

However, If you've already uninstalled and reinstalled but still seeing the same issue, it'll be helpful to contact our Phone Support team. They have the essential tools such as screen-sharing to review your accounts and further examine the root cause of this problem. They'll be able to create a new investigation about this unexpected performance of the app.  

Just go to the Help icon at the upper right of your account. Then, click Contact Us.  

Alternatively, you can open your QBO account via other supported browsers. This way, you can recapitulate achieving your business tasks in the program.

You can read through this article to learn more about the features that you can access in the mobile app: Compare mobile app features.

Keep me posted if you have other questions about using the QuickBooks Online mobile app. I'm always here to help. Stay safe!
