In the expense mode my payee box says loading... Why won't it load?

Let's perform some troubleshooting solutions to get this sorted out, go2nab. 

There are times when a browser's cache data becomes full of frequent access to web pages or damaged. This causes odd behavior when creating an invoice in QuickBooks Online (QBO). To better isolate this issue, let's try signing in to your QuickBooks Online (QBO) account using a private or incognito window. This mode doesn't use the existing cache data and helps us confirm browser-related issues. Here's how:

• For Google Chrome browser: Ctrl + Shift + N
• For Mozilla Firefox browser: Ctrl + Shift + P
• For Safari browser: Command + Option + P

Then, try entering the expense transaction again. Here's how:

1. Click the + New Plus icon. Then select Expense.
2. In the Payee field, select the vendor. If the transaction covers multiple petty cash expenses, leave this field empty.
3. Choose the account you used to pay for the expense in the Payment account field. 
4. Enter the date for the expense in the Payment date field. 
5. In the Payment method field, select how you paid for the expense.
6. In the Tags field, enter the preferred label to categorize your money.
7. Enter the expense information in the Category details section. In the Category dropdown, select the expense account you use to track expense transactions. Then enter a description. Tip: You can also enter specific products and services in the Item details section to itemize the expense.
8. Enter the Amount and Tax.
9. If you plan to bill a customer for the expense, select the Billable checkbox and enter their name in the Customer field. Learn more about billable expenses.
10. Press Save and close.

To learn more about this one, see the Enter and manage expenses in the QuickBooks Online article. If it works, go back to your regular browser and clear the cache to delete those temporarily stored files and browsing history. The overtime collection of data can create corruption, however, removing this should fix the issue. You can also use supported, up-to-date browsers to roll out the possibility of a browser-related issue.
