I recently made an employee active again after a break. I updated all his info and when I click to send him the invitation to quickbooks time, it says "invalid status".

Welcome, @gilles6. 

I appreciate you coming to the Community with your question about making your employee active again. 

Let's try a few troubleshooting steps to help resolve this problem. Using a private browser and incognito window will assist with eliminating any errors or glitches that are occurring in the system. Here's how depending on your browser session: 

• Google Chrome: Ctrl + Shift + N 
• Internet Explorer/Firefox: Ctrl + Shift + P 
• Safari: Command + Shift + N 

If this works, go back to your regular session and clear your browser's history. If not, I recommend using a different supported browser. 

Reach back out if you have any other trouble with these steps or need some further assistance. I'm always here to lend a helping hand. Have a great day!
