For years now, I've been entering sales invoices from suppliers into MYOB. Some suppliers include GST in their listed prices, and some apply it at the bottom. I know I can use the GST checkbox to make sure that the total adds up correctly in either case, **but **in every case, the figures that I input are always correct regardless. However, when toggling the checkbox to be inclusive or exclusive of GST, it will adjust the prices I've entered for the items, meaning I have to go back and fix them all over again.

Example: A book is listed as $10 on the invoice. It's inclusive of GST. With the Tax Inclusive checkbox ticked, I enter two books for a total of $20. No problems.

Example 2: A book is listed as $10 on the invoice. It's exclusive of GST. I enter two books for a total of $20, realise that the prices are exclusive of GST, untick the box, and rather than making the total $22 and keeping my values of 2x $10, it changes the values to 2x $11 for a total of $22. But even though the total is correct, the books didn't cost $11 - the listed price is $10.

Example 3: A book is listed as $8 exclusive of GST. I enter two books for $8 while the box is unticked. The total adds up correctly to $20, but it doesn't change my listed values of 2x $8.

I've just run a quick test of these examples, and the maths is off ($9.09), but the logic still stands. **Tl;dr: Toggling the Tax Inclusive checkbox alters my manually entered prices instead of keeping them intact and adjusting the Tax field instead. I consider this to be an irritating glitch and would love it to be fixed.**
