How to sort time entries by latest date auto on invoice

Welcome to the Community, @Steve O.

In QuickBooks Online (QBO), the ability to automatically sort time entries by their latest date is currently unavailable. You will need to manually click the Filter drop-down to change it to your preferred date.

Here's how:

1. In QBO, go to the + New option at the top left to create Invoice.
2. Select the customer's name.
3. In the Add to Invoice at the right pane, click the All dates drop-down in the Filter by section and choose your preferred date. You can also pick a Custom date. 
4. Tick Add on the Time entries to include them in the invoice.
5. Hit Save and close once done.
