Installation

Add this line to your application's Gemfile:

gem 'strikeiron'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install strikeiron

Usage

Usage of strikeiron requires access to Strikeiron Online Sales Tax API.

1. Configure the client

Strikeiron.configure do |config|
  config.user_id  = 'your_strikeiron_user_id'
  config.password = 'your_password'
end

2. Obtaining a list of categories

Performing the category lookup does not count against your hits. For performance reasons, I recommend you keep a cached copy. A database is a good start.

categories = Strikeiron.tax_categories
# => [{:category=>"Alcohol", :category_id=>"01051000"}, {:category=>"Alcoholic Beverages", :category_id=>"01050000"}, {:category=>"Beer", :category_id=>"01052000"}, {:category=>"Books", :category_id=>"01501500"}, {:category=>"Charges necessary to complete sale other than delivery and installation", :category_id=>"04800000"}, ...]

3. Calculate sales tax

from  = Strikeiron::Address.new(:street_address => 'One Microsoft Way', :city => 'Redmond', :state => 'WA', :zip_code => '98052')
to    = Strikeiron::Address.new(:street_address => '902 Broadway', :city => 'New York', :state => 'NY', :zip_code => '10010')
items = [
  Strikeiron::TaxValue.new(:category_id => '01151605', :amount => 239.41),
  Strikeiron::TaxValue.new(:category_id => '01151605', :amount => 239.41)
]

response = Strikeiron.sales_tax(
  :from       => from,
  :to         => to,
  :tax_values => items
)
# => #<Strikeiron::TaxResult @from=#<Strikeiron::Address @street_address="ONE MICROSOFT WAY", @city="REDMOND", @state="WA", @zip_code="98052">, @to=#<Strikeiron::Address @street_address="902 BROADWAY", @city="NEW YORK", @state="NY", @zip_code="10010-6041">, @tax_values=[#<Strikeiron::TaxValue @category="Computer Software (both prewritten and non-prewritten) delivered electronically", @category_id="01151605", @tax_amount=21.25, @jurisdictions=[#<Strikeiron::Jurisdiction @fips="36", @name="New York", @tax_amount=9.57>, #<Strikeiron::Jurisdiction @fips="CTD51000", @name="METRO COMMUTER TRANS.
