If we enter 3 items at $10 each, but then realise that GST was not reflected in the total price of these items, it would be nice to be able to keep the entered values of $10 in our form rather than reducing them automatically to $9.09 when the GST Inclusive box is manually unticked, for example. It would be much more convenient if the total was adjusted to match the items, rather than the items being automatically adjusted to match the total.
Likewise, if we enter those 3 items at $10 each but then realise GST WAS included in their price, it would be nice to keep the values at their original price rather than having all of their values automatically rise by 10% (to $11 each) the moment the GST-inclusive box is ticked.
It seems simple enough to fix manually with an example of three items at $10, but it isn't really practical to go through and amend dozens of prices from a supplier's invoice with values ranging anywhere up to $1000. Our suppliers might as well be alternating between including GST in their item prices and including it as a small lump sum at the end, so it would really be good to be able to move between these two invoice billing types fluidly without losing time having to re-enter all the correct prices if a supplier's invoice is formatted in such a way that the pricing method used isn't immediately apparent.
