Hi there Judy Pei,

It's important that all your transactions are entered correctly for your books to be well balanced. QuickBooks Online is a great tool able to help you keep track of sales and expenses so you can see the profit of your company. I can provide some information about invites.

The first step I recommend would be to reach out to the admin of the account and delete your user before inviting you again. Sometimes just sending a new invite can resolve any issues relating to invites. If the error persists, then one possible cause for failed invitations would be browsing data. These temporary files can accumulate in your browser, device and network and cause errors in any cloud-based software like QuickBooks Online. Here are some steps to try before sending a new invite once more, and also to try before trying to accept the invite:

• Clear your browser cache if you're using a browser
• Try a browser if you're using the app
• Try deleting the app from your device, and installing it once more from the app store
• Try a private browser window
• Try another browser type
• Make sure you're using a supported browser and system
• Reset your Internet or try on another computer or device

Let me know if this resolves the error, or if you have any other questions.
