Hi,
I Worked hard last two days to customize your nice script (congrats!) to fit my needs.
While layout customization can be done with the templates there are some that requires the script hack. It's not a big deal for me, fortunately, but they requires to re-hack the script on every upgrade. It would be nice if you would include the following (in bold) in view/invoice/templates/default.php:

$items = "";

$taxes = "";

$payments = "";

$payments2 = "";

$subtotal = 0 ;

$netSubtotal = 0;

$totalDiscount = 0;

$netDiscountedSubtotal = 0;

$outstanding_payments = 0;

if(!empty($this->items)){



	$taxesArray = array();



	foreach($this->items as $item){

		

		// product net price

		$netPrice = $item->value * $item->amount;

		

		// net subtotal

		$netSubtotal += $netPrice;



		// net discounted subtotal

		$netDiscountedPrice = (($item->value * $item->amount) - $item->discount);

		

		// net discounted subtotal sum

		$netDiscountedSubtotal +=  $netDiscountedPrice;

		    

               // product tax

		$item->items_tax = (($item->value * $item->amount) - $item->discount)*($item->tax/100);

		

		// array tax regrouped

               // with Hikashop $this->taxes is not valorized so the standard routine is skipped

		if(!isset($taxesArray[$item->tax])) { $taxesArray[$item->tax] = $item->items_tax; }

		else { $taxesArray[$item->tax] += $item->items_tax; }

For the same reason you should process it separately

if( count($taxesArray) > 0 && empty($this->taxes))

{

	while(list($k,$v)=each($taxesArray))

	{

		if($v >0)

		{

			$search = array(

							"{name}",

							"{value}"

						);

			$replace = array(

							$k,

							InvoicesHelper::format($v, $before, $after)

							);

			$taxes .= str_replace($search, $replace, $this->template->taxes) ;

		}

		

	}

}

Obviously you should include those variables in the

$items .= str_replace($search, $replace, $this->template->items) ;

and in

echo str_replace($search, $replace, $this->template->content) ;

So far all the variables that european invoicing laws require (even if not everybody respect them...), so them should be there.

And it would be very nice to get all payment details available and not just "Payment" listed as invoice items (like the title of payment type, "Paypal", "Wire Transfer" and so on) and shipping details as well. Or, alternatively, fire the plugins before each "search/replace" command so user could develop a customized one without hacking the core.
