How to fix error H101, H202, H303, or H505?

If you’re seeing errors H101, H202, H303, or H505, you’re likely using a QuickBooks Desktop product. QuickBooks Online is entirely cloud‑based—you sign in through a browser or mobile app without opening a local company file. These error codes do not occur in QuickBooks Online.

What to do if you’re having trouble opening QuickBooks Online

If you’re still unable to access your company after these steps, contact QuickBooks Online support for personalized help.
