This strange behavior in QuickBooks may be browser-related. There are times when the stored cache affects how the program works when creating invoices.

To resolve this, I'd suggest logging in to your QuickBooks Online account via a private window. This doesn't use the existing cache files, which makes it a good place to determine if there's an issue with the browser.  

Here are the keyboard shortcuts: 

• Safari: Command + Shift + N 
• Google Chrome: CTRL + Shift + N
• Mozilla Firefox or Microsoft Edge: CTRL + Shift + P 

Once logged in, recreate your invoice. If it works, let's clear the browser's cache. This helps the program performs efficiently.

If private browsing doesn't work, you can use other supported browsers. They also provide the best and most secure experience with QuickBooks.

Hi that didn’t fix the issue it’s still doing the same thing and this is on a mobile device on the QuickBooks app

I appreciate you for keeping in touch with us, larccllc-gmail-c.

Since you're using the QuickBooks app, I have a different troubleshooting step that you can follow to fix your issue where the quantity of your products is reset after entering.

Let's start by clearing your app's data. This helps refresh applications and eliminates common issues that cause your behavior like the one you're experiencing. If you haven't tried the following steps, I suggest performing them.

Clearing the app's data can be done on the app or on your phone settings. The instructions are outlined below:

• For QuickBooks Online app:
  
  • Android - Select the menu at the top right and choose Settings. Then select Refresh Data and choose Yes.
  • iOS - Select the menu at the top right and then choose Help & Feedback. Then select Refresh Data and Refresh.
    
• In your Phone Settings:
  • Android - From your phone's settings, select Apps (varies by device). Choose the QuickBooks app from the list and select Storage. Select clear data.
  • iOS - From your phone's settings, select Settings, then, click on General and choose iPhone Storage. Select an app that's taking up a lot of space. To free up the storage without deleting the documents and data for the app, select Offload App.
