AfipBill allows you to generate an AFIP bill in PDF format.
The end result will look like this: bill_sample.pdf
Include the gem in your Gemfile
gem 'afip_bill'Install it
$ bundle installIn order to have the bills fully complete, you will need to setup some configuration about your business. If you're in a Rails application you can place that in config/initializers/afip_bill.rb
AfipBill.configuration[:header_business_name] = "Company Name"
AfipBill.configuration[:business_name] = "CompanyName SRL"
AfipBill.configuration[:business_address] = "Address 1234"
AfipBill.configuration[:business_start_date] = "01/01/2016"
AfipBill.configuration[:business_cuit] = "1234567890"
AfipBill.configuration[:city] = "Ciudad de Buenos Aires"
AfipBill.configuration[:ingresos_brutos] = "123-456789-0"
AfipBill.configuration[:iva] = "IVA Responsable Inscripto"
AfipBill.configuration[:sale_point] = "0001"Also, one of the main things that you need to have, is a JSON for each of your bills. It must contain at least these attributes:
json_bill = {
cae: "1234567890123", # CAE number
cae_due_date: "20171125", # CAE expiry date
doc_num: "12345678901", # CUIT number
cbte_tipo: "01", # Bill type (01 = A, 06 = B, 11 = C)
cbte_fch: "20170125", # Bill date
imp_neto: 220.0, # Net amount
imp_iva: 46.2, # IVA amount
imp_total: 266.2, # Total amount
cbte_hasta: 1, # Voucher number
fch_serv_desde: "20170101", # Invoiced from
fch_serv_hasta: "20170131", # Invoiced to
fch_vto_pago: "20170115" # CAE expiration date
}.to_jsonIn OmbuShop, we like to automatically generate this JSON using Bravo.
There are three important classes that you need to use: AfipBill::User,
AfipBill::LineItem and AfipBill::Generator.
You should create a new instance of this class to provide some information about the bill. It receives four parameters: Company name, Owner name, Address, and Tax category.
user = AfipBill::User.new("Bill company name",
"Bill owner name",
"Bill address",
"Bill tax category")With this class you can define the line items for your bill. It receives three parameters: Name, Quantity, and Unit amount.
item_1 = AfipBill::LineItem.new("Item 1", 1, 100)
item_2 = AfipBill::LineItem.new("Item 2", 1, 120)
...This class will generate the PDF bill. It receives three parameters: the json bill, the user, and the array of line items (all the parameters were defined above)
generator = AfipBill::Generator.new(json_bill, user, [item_1, item_2])And finally you can render the PDF by using the generate_pdf_string method
generator.generate_pdf_stringOr if you're in a Rails app you can render it like this:
respond_to do |format|
format.pdf { render text: generator.generate_pdf_string }
endAfipBill was inspired in code by nubis and gastonconcilio.
Initial development of this gem was sponsored by OmbuShop.
