Hello @Rashid. 

Let's resolve the issue you're having while working on syncing the process with Timely App to QuickBooks Online.

If this error blocks you from linking your transactions to QuickBooks Online, I suggest contacting Timely App support. This way, they can further investigate why this error keeps appearing on your end.

Please visit this link: https://quickbooks.intuit.com/app/apps/appdetails/timely/, then navigate to the Support section under the App information. Once open, press the Get Support button.

If everything is fine, you can move forward with creating a report in QuickBooks Online to give a snapshot and overview of your invoices and bills.

It's been a pleasure being with you today. Thank you reach us. Have a delightful day.
