}

Contracts

Invoices

An invoice is a object inheriting from AbstractInvoice. It is composed of an ID, a customer (represented by CustomerInterface) and two dates: the due date and the creation date (these two are represented by Carbon instances).

It provides abstract methods to compute the total price (with and without taxes). The french VAT rate is currently hard code into the AbstractInvoice class ($vatRate static property) but will be extract in a future release. Implementations of AbstractInvoice don't have to use this value. The VAT amount is compute base on the subtraction between the implementation of the getIncludingTaxTotalPrice and the getExcludingTaxTotalPrice abstract methods.

A payment (represented by PaymentInterface) can be set in order to have a paid invoice (with the method isPaid).

Containers

An invoice is also a container of items and a container of groups of items.

An item (represented by ItemInterface) is a simple line of the invoice (name, quantity, unit prices and total prices with and without taxes).

A group of items container (represented by GroupOfItemsInterface) has a name. As an invoice, it's a container of items and a container of groups of items recursively.

Invoice generation

An invoice could be generated into HTML thanks to HtmlGeneratorInterface or in PDF thanks to PdfGeneratorInterface (note that our implementation of PdfGeneratorInterface requires an HtmlGeneratorInterface implementation).

Implementations

Invoices

This package provides two implementations of AbstractInvoice:

  • ExcludingTaxInvoice which sum all the excluding tax prices of the items and group of items and then compute the including tax price based on that value.
  • IncludingTaxInvoice which sum all the including tax prices of the items and group of items and then compute the excluding tax price based on that value.

Containers

This packages also provides basic implementations for ItemInterface (Item) and GroupOfItemsInterface (GroupOfItems)

Generators

The implementation of HtmlGeneratorInterface is named HtmlGenerator and is based on Laravel Views.

An implementation of PdfGeneratorInterface named PdfGenerator is provided based on PhantomJS (a javascript browser). Our implementation of PdfGeneratorInterface requires an implementation of HtmlGeneratorInterface to process.
