I don't understand where the GST is on my created invoice. It just has the total amount for services not added GST

This issue has been investigated, donnamurphy.

We've received some reports why the GST is not included when creating an invoice. Our engineers is working diligently to fix this issue as soon as possible. 

On the other hand, I'd recommend contacting our Phone Support team so your name will be added to the list or affected users. I'll show you how:

1. Click the ? Help icon, and then Contact Us.
2. Enter GST not included when creating invoice as your keyword.
3. Click Let's talk.
4. From there, you can Start a chat or Get a callback.

Either my colleagues or I will update this thread once a fix is available.
