Hi karasik054-gmail,
QuickBooks is an easy-to-navigate program that helps you to manage your accounting with ease. I'll be glad to share more info so you're on the right track with your work.
I'd like to start off by troubleshooting the error you're receiving to determine if it's a browser-related issue. Clearing cache and cookies is a great way to clean your browser allowing it to work more efficiently. Here's an article that shows you how to do that: Clear cache and cookies.
If you are still unable to create and save your invoice, I encourage you to contact our support team so they can assist you further with this. Here are our contact details:
- Schedule a Callback or start a Chat: click (?) in the upper right in QuickBooks Online > enter "Contact support" > choose Contact Us > provide a brief summary > select Let's Talk > choose Get a callback or Start a Chat.
- Social Media: Facebook, Twitter, and Instagram.
- Support hours are from Monday to Friday between 9 a.m. and 8 p.m. ET.
I'll be one message away in case you need further assistance.
