You want to group line items into subtotals by type so your customers can more easily understand what you're billing them for? Wow, how advanced! That's a really cool idea! It's almost like rocket science. Or brain surgery. You can't really expect QuickBooks Online to support such a complicated and advanced concept, can you?

I mean, sure, QuickBooks Desktop has supported subtotals, subtotals within subtotals, discount percentage calculations that work on both, in-line sales tax calculations on them, and other similarly way-to-advanced for QuickBooks Online features for, you know, decades.

But then QuickBooks Desktop is real, actually useful, accounting software. Be sure not to get that confused with QuickBooks Online. The key to being a happy QuickBooks Online user is to set the bar very, very low. Then you'll be happy when, say, the site isn't down, or the login actually works, or when you can figure out how to do anything without struggling.
