My customer list won't load.

Let me help with your question about the customer list in QBO, hearthandstonevt.

I'd also like to ask if you're getting an error message or is the customer page just spinning around. A possible browser issue might have caused the customer list to not show up successfully. I'll share some of the most common steps that can resolve unexpected results in QBO. 

Start by using an incognito/private browsing session or a different browser. Here are some of the keyboard shortcuts to quickly open an incognito session: 

• Ctrl + Shift + N  for Google Chrome
• Ctrl + Shift + P for Firefox
• Control + Option +P if you're using Safari
• Ctrl + Shift + P for Microsoft Edge

 
Then, log back in and check if you can already see and work in the customer list section.  If you're able to do that, follow the steps in this article to delete your browsing history: Clear Cache And Cookies To Fix Issues When Using QuickBooks Online.

Here's an extra article for additional guidance and reference as well: Add and Manage Customers in QuickBooks Online.
