Guys just so I understand what is going on here. I understand that GST in Manager is calculated on a line by line basis and then summed, correct?

So using the example above I manually calculated the GST on Total and Line by and then summed to give the GST inclusive total.

Am I totally messed up here because processing both ways I get the same result but Manager calculates slightly different? How does Manager sneak in the extra cent to give **$809.98**? Look at the rounding it is already rounding up.

OK here is a bit moreâ€¦ rounding at each line then summing

I get the horrible feeling these guys / Ariba are right at rejecting my invoices and Manager is wrong?

By the way the Head Office we deal with is in AU.

Look at example â€¦ I do not think so.
