I went to invoice last night and the Google calendar connection is not working - all of my chargeable time is in there - any ideas when it’s coming back

Hi there, Itsmith.

Thank you and welcome to QuickBooks Community. I'll share steps to ensure that the google calendar connection will come back to continue running with your business. 

It could be that there's a delay with the connection on the app. To isolate this, I recommend re-establishing a new connection with Google calendar to ensure that you get the most recent version of the application. To start with, you'll need to go to the Apps menu.

Here's how:

1. Click Apps in the left navigation menu.
2. Select Find Apps section. Then, click the Browse Category drop-down menu, select Sync Data.
3. Search for Invoice with Google Calendar, then select the App.
4. Click Get App Now and complete the following on-screen instructions.

Please refer to this article to see additional information on how Google calendar imports your calendar events to your invoices so you can bill for your work: How to set up and use Invoice with Google calendar.

Let me know how it goes by leaving a reply below. I'm always here to help you further with Google calendar in QuickBooks Online.

In checking and from a search the attached was found and it seems there is a QB back office tech team on the case - can I be added to any updates on this case number - desperate to get invoices raised and don’t want to go back to drafting them up line by line when Google calendar has all the info.

Ive tried all the checks several times and deleted and added again the app in the hope it had been fixed but no luck so far - there are lots using this app and I’m guessing at the end of the month there will be many more calls
