Hi there!
We are here to help!
I can see you have reached out via the digital assistant, so just to recap what Margarita shared with you in your private message, in case anyone else following along finds it helpful too!
If you want an item to cost a total of $100 including GST, you’ll need to enter it as $90.91, Solo will automatically calculate and add the GST for you.
To work it out manually, divide the total amount by 11 to find the GST portion ($100 ÷ 11 = $9.09), then subtract that from the total.
Also, just a heads-up, the inclusive/exclusive setting in Solo only controls how GST is displayed on the invoice. It doesn’t change the way Solo calculates it behind the scenes.
Let us know if this solves the issue you are experiencing, if not, then we'll jump right in and save the day!
