Hello there, @KAJinPGH

I understand how frustrating it can be when we encounter difficulties adding all time entries. Let me provide you with some details on how to add all time entries through invoices in QuickBooks Online (QBO).

After the recent update, we can now add all time entries in QuickBooks. To do this, simply follow these steps:

1. Go to Sales and select Invoices.
2. Locate the Invoice that you want to add time entries to and click Edit.
3. In the invoice interface, select the Manage option or the small gear icon and then choose Suggested Transactions in the Suggestions section.
4. Select the Add All option or choose the Billable time that you want to add to that invoice.
5. Review the entries and select Save and Close.

You can also refer to the screenshot provided below for visual guidance:
