See Invoices: How to properly round and calculate totals
Usage
Invoiced handles money amounts in cents.
Discount Resolver
Discount resolver runs a set of custom rules in charge of figuring out an amount to subtract from a given product price.
Defining a custom rule
class TwentyPercentRule implements RuleInterface
{
protected $product = null;
public function __construct(\Product $product)
{
$this->product = $product;
}
public function getAmount()
{
return $this->product->getPrice() * 0.2;
}
}
Running the rules
use Sirprize\Invoiced\BasePrice\Discount\Resolver;
use Sirprize\Invoiced\BasePrice\Discount\RuleInterface;
$product = new \Product(); // this can be anything really...
$resolver = new Resolver(Resolver::BEST); // the rule returning the biggest amount wins
$resolver->addRule(new TwentyPercentRule($product));
$discountAmount = $resolver->getAmount($product->getPrice());
$finalPrice = $product->getPrice() - $discountAmount;
Invoice
Invoice Line Item
use Sirprize\Invoiced\VatPrice\LineItem;
$lineItem = new LineItem(780, 19, true, 1); // $amount, $vatRate, $priceIncludesVat, $quantity
// line item totals
$lineItemGrossTotal = $lineItem->getPrice()->getGrossAmount();
$lineItemVatTotal = $lineItem->getPrice()->getVatAmount();
$lineItemNetTotal = $lineItem->getPrice()->getNetAmount();
// unit
$unitGrossAmount = $lineItem->getUnitPrice()->getGrossAmount();
$unitVatAmount = $lineItem->getUnitPrice()->getVatAmount();
$unitNetAmount = $lineItem->getUnitPrice()->getNetAmount();
Invoice Sum
use Sirprize\Invoiced\VatPrice\LineItem;
use Sirprize\Invoiced\VatPrice\Sum;
$sum = new Sum();
$sum
->addLineItem(new LineItem(780, 19, true, 1))
->addLineItem(new LineItem(2500, 7, true, 1))
;
$grossTotalAmount = $sum->getPrice()->getGrossAmount();
$vatTotalAmount = $sum->getPrice()->getVatAmount();
$netTotalAmount = $sum->getPrice()->getNetAmount();
Subtotals
Invoices often feature all kinds of subtotals such as discounts, items total, shipping and handling etc.
Base Price
A base price is just a simple object holding the baseprice, the discount amount and the final price of a product:
use Sirprize\Invoiced\BasePrice\Price;
$price = new Price(1000, 220); // $baseAmount, $discountAmount
$baseAmount = $price->getBaseAmount();
$discountAmount = $price->getDiscountAmount();
$finalAmount = $price->getFinalAmount();
Base Price Line Item
use Sirprize\Invoiced\BasePrice\LineItem;
$lineItem = new LineItem($price, 3); // $price, $quantity
// line item totals
$lineItemBaseAmount = $lineItem->getPrice()->getBaseAmount();
$lineItemDiscountAmount = $lineItem->getPrice()->getDiscountAmount();
$lineItemFinalAmount = $lineItem->getPrice()->getFinalAmount();
// unit
$unitBaseAmount = $lineItem->getUnitPrice()->getBaseAmount();
$unitDiscountAmount = $lineItem->getUnitPrice()->getDiscountAmount();
$unitFinalAmount = $lineItem->getUnitPrice()->getFinalAmount();
Base Price Sum
Base prices are then added to line items and summed up:
use Sirprize\Invoiced\BasePrice\LineItem;
use Sirprize\Invoiced\BasePrice\Sum;
use Sirprize\Invoiced\BasePrice\Price;
$sum = new Sum();
$sum
->addLineItem(new LineItem(new Price(1000, 220), 3))
->addLineItem(new LineItem(new Price(3000, 500), 10))
;
$baseTotalAmount = $sum->getPrice()->getBaseAmount();
$discountTotalAmount = $sum->getPrice()->getDiscountAmount();
$finalTotalAmount = $sum->getPrice()->getFinalAmount();
