should i be able to retrieve old invoices from recently cancelled account?

Yes, you should be able to have read-only access to your invoices for one year after canceling your QuickBooks Online account.

To help us figure out why you're currently blocked, are you seeing a specific error message when you try to open them? Any details you share will help us get this sorted out for you.

In the meantime, try logging into your account using a private or incognito window. This bypasses common browser issues, and check there if your invoices are accessible. You can also use other browsers as an alternative.

I’ll keep this thread open in case you have any details to share or follow-up questions!
