Magento – Magento automatically round up product price based on applied VAT

pricerounding

I need to rounds up the including vat sell price to closest £0.99 ie. if sell price for an item including vat is £10.52 it rounds up the sell price inc vat to £10.99 . In other words, so sell price always ends with £.99 at the end.

And the website automatically will need to change the excluding vat price to exactly 20% less that the rounded up price.

I believe there is some event where I can hook a function to apply this round up logic?

This is similar to the "5 Rappen Rounding" in Switzerland, where the total always is a multiple of 0.05.

There is an extension for it that you should be able to build upon: https://github.com/openstream/Magento5CentRounding - it rewrites the subtotal and grandtotal models and hooks into their collect() methods.

Magento – Get Product Price After Catalog Rules And Vouchers

If I understood correctly, you need the price at which the product has been sold.
You can get that price directly from the order item.
On the success page you have access to the last order it with:

$orderId = Mage::getSingleton('checkout/session')->getLastOrderId()

Then loop through the order items until you find the product you need:
Let's say the product you are looking for is $productId

$order = Mage::getModel('sales/order')->load($orderId);
$price = null;
foreach ($order->getAllItems() as $item){
   if ($item->getProductId() == $productId){
        $price = $item->getPrice() - $item->getDiscountAmount();
        break;
   }
}
if (!is_null($price)){
    //do something with $price
}

There is no point on applying a rule to the main product. You can get wrong results. For example some rules may be applied only on a certain combination of products are in cart, or when a specific shipping address is set. Also one rule cannot be valid anymore (customer or total capping can be reached).

Price Rounding – How to Round Price to 4 Decimal Places

This method is one of the places, where we fought rounding issues in the past. It might be, that you get problems with rounding, if you round more decimal places (sounds weird I know).

But beside f*cking up your prices I don't see a problem.

So: TEST TEST TEST.
