Hi there, jodiecball.

Allow me help and to provide some insights about the time format in QuickBooks. 

Since QuickBooks Online (QBO) and QuickBooks Desktop (QBDT) are two different versions, they have different platform design and some features work differently just like the invoice time entry format.

Your sentiments are being noted. It's always our goal to improve our clients experience while working with the software. In the meantime, I encourage you to get in the loop about the latest news and product developments in QuickBooks through this link: Firm of the future.

Please know that you're always welcome to drop by if you have any other concerns with invoice entry format. Have a great day
