# Link: https://gist.github.com/iloveitaly/8e6bce2aec361dce38b5c61c48d037ea
# 
# Usage:
#   gem install stripe
#   export STIRPE_KEY=sk_test_123
#   ruby create_standalone_manual_invoice.rb

require 'stripe'

Stripe.api_key = ENV['STRIPE_KEY']

customer = Stripe::Customer.create({
  description: "Sample customer",
  email: "sample@example.com"
})

# NOTE adding a payment source is omitted here since you are creating a invoice for manual payment

invoice_item = Stripe::InvoiceItem.create({
  customer: customer.id,
  amount: 50_00,
  currency: "usd",
  # this description appears on the line item level in NetSuite
  description: "A line item",

  # NOTE you can specify exactly which NetSuite line item you'd like to connect to
  #      using metadata. More info: https://dashboard.suitesync.io/docs/field-customization
  # metadata: {
  #   netsuite_service_sale_item_id: 123
  # }
})

# creating this invoice in Stripe will create an open invoice in NetSuite
# if you manually pay the invoice in Netsuite, the payment information is pushed
# back to Stripe and the invoice is marked as paid.
# More information:
#   https://dashboard.suitesync.io/docs/invoices#manual-invoice-payments
#   https://stripe.com/docs/subscriptions/ach-credit

invoice = Stripe::Invoice.create(
  customer: customer.id,
  billing: 'send_invoice',
  days_until_due: 30
)

puts "Stripe Invoice ID #{invoice.id}"

# NOTE with SuiteSync enabled, the NetSuite invoice ID is added to the Stripe metadata
#      shortly after it's created.
