Using QB Online and we have updated one of our services so that it shows under a new heading in the P&L, however only new invoices seem to show this change.

This behavior in QBO is working as designed, TomCross.

When you make some changes to a service item, it will not affect the previously entered transactions. This is because you recorded them using the old setup, and they were already accounted for in the program. The change will only take effect on the newly entered invoices and other transactions.

For tracking purposes, I'd suggest going back to the old invoices and editing them. This way, they'll use the new update that you've made and will show on the new heading of your Profit and Loss report.

Here's how:

1. Click Sales on the left panel.
2. Go to the Invoices tab.
3. Find the old invoices you've entered.
4. Edit as necessary.
5. Click Save and close.
