I have to add an employee but don't have an ;add employee' button. What can I do?

I'll happily assist you in adding your employee, Adam D1.

Sometimes, QBO will not show some features and buttons due to packed memory usage. In the meantime, I recommend using a private browsing window that doesn't store files. Browsers use cache and cookies to load web pages faster.

To open an incognito window, you can refer to these keyboard shortcuts:

Google Chrome: Press Crtl+Shift+P
Microsoft Edge & Mozilla Firefox: Crtl+Shift+N
Safari: Press Command+Shift+N

If you can find the add an employee button, consider returning to your regular browser and clearing its cache and cookies. 

If you still have the same result, I suggest utilizing another supported browser. It can help us identify if the issue is specific to your current browser.
