# EuropeanVat

European Union VAT utilities for Elixir.

This library contains functions to:

* sanitize European VAT numbers
* check if VAT must be charged for a given transaction
* check the validity of a VAT number using the [VIES web service](http://ec.europa.eu/taxation_customs/vies/faq.html)
* obtain up-to-date VAT rates for all EU countries

This library was inspired by the [eurovat](https://github.com/phusion/eurovat) gem but includes additional features.

## Installation

_This library is still a work in progress and **has not been published yet** on Hex._

The package can be installed via Hex as:

1. Add european_vat to your list of dependencies in `mix.exs`:

def deps do
          [{:european_vat, "~> 0.0.1"}]
        end

2. Ensure european_vat is started before your application in `mix.exs`:

def application do
          [applications: [:european_vat]]
        end

## Usage

### VAT Number Sanitization

```Elixir

EuropeanVat.sanitize(" BE 0829.071.668  ")
# "BE0829071668"

EuropeanVat.sanitize("be0829071668")
# "BE0829071668"

```

### VAT Applicability Check

```Elixir

# Buyer and seller in the same country
EuropeanVat.charge?("BE", "BE", "BE0829071668")
# true

# Buyer and seller in different EU countries, VAT number present (business)
EuropeanVat.charge?("NL", "BE", "BE0829071668")
# false

# Buyer and seller in different EU countries, no VAT number (consumer)
EuropeanVat.charge?("NL", "BE", nil)
# true

# Seller in EU, buyer outside of EU, no VAT number
EuropeanVat.charge?("BE", "US", nil)
# false

```

### VAT Number Verification

> Before interacting with the VIES web service, you **must** start the EuropeanVat application (see Installation).

Going forward, you can use the `check/2` function to verify VAT numbers:

```Elixir

EuropeanVat.check("BE", "0829.071.668")
# {:ok,
#  %{address: "RUE LONGUE 93\n1320 BEAUVECHAIN", country_code: "BE",
#    name: "SPRL BIGUP", request_date: {{2016, 1, 24}, 60}, valid: true,
#    vat_number: "0829071668"}}

```

### VAT Rate Lookup

> Before interacting with the VAT rates lookup service, you **must** start the EuropeanVat application (see Installation).

You can lookup up-to-date VAT rate information based on a ISO-3166-2 country code:

```Elixir

EuropeanVat.rate("FI")
# %{"country" => "Finland", "parking_rate" => false, "reduced_rate" => 14.0,
#  "reduced_rate_alt" => 10.0, "standard_rate" => 24.0,
#  "super_reduced_rate" => false}

```
