Gives an error when trying to create a invoice

I'm here to make sure you'll be able to create an invoice in QuickBooks Online (QBO), kurtyksnow. 

Before doing so, can you share the error message you're encountering when creating an invoice? It'll help me collect the necessary details and provide you with the appropriate information. A screenshot of your view will be very much appreciated. 

In the meantime, we can perform some troubleshooting steps to fix this. There are times when the browser is full of frequently accessed page resources, which causes some errors or unusual responses. 

Let's start accessing your account using a different or private browser. You can use either of these shortcut keys:

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

If it works, I recommend clearing your browser's cache. Doing so will remove the historical data and access QuickBooks with a clean slate. You can also switch to a different supported browser.

Once everything's fine, you can categorize the transactions. Here's an article as your guide: Categorize and match online bank transactions in QuickBooks Online.

Let me know if you need anything else or should you have more questions about creating an invoice in QBO. I'll be sure to help you out again.

 Invoices I had active allow me to add services to them but when I click on a customer to create a new invoice I get this msg and a blank screen. Been getting this msg for 8 days. I use the mobile app there are no updates available 

Good morning, @kurtyksnow.

Thanks for following up with us, and letting us know that you're using the QuickBooks Online mobile app. 

You can perform some fixes on any app-related issues to rectify stored cache data on your mobile app. Here's how:

1. Change the Wi-Fi data connection on your device to 4G (this varies by device).
2. Close and restart the app.
3. Clear app data. To do this:
   1. Open your device Settings.
   2. Select Apps.
   3. Choose the QuickBooks app from the list, then select Storage.
   4. Select clear data.
4. Power down and restart your device.
    

Additionally, you'll want to consider opening your QuickBooks Online account in a webpage browser on your device. You can access your account and continually perform your QuickBooks tasks from there.

Please let me know if you continue to have issues while using the app. I'm here if you have any additional questions or concerns. Take care! 

None of that works I can create a invoice if I'm not using the app I have to go into the internet browser but it's inconvenient but that'll have to work for now.  If they don't fix the app issue I'll have to find a different service don't have time to screw around I'm a busy guy thats why I use the mobile app

Don't worry, I am here to help you. Allow me to share some that can help your concern.
