I have tried to use ORDER_EDIT 2.9.1, but i found following major bugs in VAT calculation:
1. VAT calculations (specially in Javascript) are usual done in un-correct way, specially when you have
DISPLAY_PRICE_WITH_TAX set to TRUE
2. tax rounding is default set to 4 decimal places, which is for me (SLOVAKIA) bad, because we have 1 decimal place rounding rule
I have rewritten order_edit to make things OK with steps above, but I want to point to contrib creator, that this thing should be fixed!
typical mistake is f.e.tax calculation without rounding set properly
//removed by MGX $RunningSubTotal += (($products_details['tax']/100 + 1) * ($products_details['qty'] * $products_details['final_price']));
$RunningSubTotal += Round($products_details['final_price'] * ($products_details['tax']/100 + 1),1) * $products_details['qty'];
My contrib needs following to be setup OK:
1. decimal tax place set 1 -> should take variable from admin (do you know how?)
2. installed ot_round contrib (I round according SK law final price at 0.5 down or up)
