My time tracking is in decimal hours, but my invoice keeps formatting in hours:min. how can i change the time format (like one can with QuickBooks Desktop)?

Are you using TSheet or other app?

I also hit this issue and a customer pointed it out to me. My compromise was to change the header to "Hrs:Min" to remove confusion. But a fix would be highly appreciated.

Why is this still not addressed by quickbooks? It is a BIG PROBLEM for invoicing when everyone expects it in decimal and not HR:MM. There should just be an option check box in the invoice style sheet for this. 

I think it is an outrage that for years QB users have asked for this issue to be resolved and nothing has been done about it. The auto responses received by QB staff is insulting and so is asking for us to pay more for a 3rd party application to resolve the issue ourselves. When will QB step up and pay attention to its customer's needs? We want hours in decimal format!! Sending invoices to clients that show inconsistent formatting under the time column reflects poorly on us and creates confusion. I regret moving over to QB due to poor customer service and its non-intuitive platform.
