Why can't I invoice a customer

Good morning, mark358.

I appreciate you joining us here in the Community. I'd be happy to provide some information on why this may be happening.

Sometimes browsing data accumulates and prevents the software from doing what it is supposed to do. I recommend clearing your cache and cookies, switching to another browser, or trying a private browser. This usually resolves browsing data issues.

If you're still receiving this message after trying the steps provided, I encourage you to reach out to the support team outside of the Community so they can investigate further into why this may be happening. You can reach them by following one of these methods:

Schedule a Callback: click (?)Help in the upper right > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback. 

You can also check the Get help with QuickBooks products and services article for the support hours.

Feel free to reach back out if you have any other questions.
