When I try to create an invoice it says can't connect to there network

Hi, @ashleyfromang. 

When we experience unforeseen situations when using QuickBooks, it's advised to perform basic troubleshooting steps to identify if this is a browser-related issue. 

Your browser's cache saves files on your computer to enable the website to download faster on your next visit. However, it can also get outdated over time, leading to problems in accessing websites. To get started, we have to open your QuickBooks Online (QBO) account on an incognito window. Doing so will prevent the browser history from being saved. 

Please refer to the following keyboard shortcuts based on your browser type:

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

If the private browsing session works, clear the browser's cache so the system can restart. This task is also possible in other supported, up-to-date browsers. Clearing the cache will reboot the system, allowing you to work with a clean slate. 

In addition, refer to this article to learn how to record payments when your customer pays you in QBO: Record invoice payments in QuickBooks Online.
