Hi there, sher422.
There are times that an issue like this occurs when we encounter a browser-related issue. We can fix this by running some basic troubleshooting steps.
To start with, let's open QuickBooks on an incognito window. This is where we can identify any browser-related issue. You can use these keyboard shortcuts to open one:
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Microsoft Edge: Ctrl + Shift + P
- Safari: Command + Shift + N
If you're able to create an invoice, you can go back to a regular browser and clear its cache. A piled cache can also be the reason for some unexpected issues on the opened pages like QuickBooks.
You can also switch to a different supported browser like Mozilla Firefox, Google Chrome, Microsoft Edge, or Safari.
Also, if you want your clients to pay the invioces online, you can set up payments. You can check these articles for more information:
