SuperFaktura

SuperFaktura is an easy to use online app, that allows you to create great looking online invoices, proformas, price estimates, orders, delivery and credit notes. You can invoice in foreign currencies and languages. Accept payments online, organize your stock management, send electronic invoices online, or in paper form via hybrid post.

This module integrates Superfaktura API to Drupal Commerce, so you can issue invoices via this service. Majority of the data that Drupal Commerce supports by default is submitted. That includes:
- Invoice number
- Issue date
- Delivery date
- Due date (you can set default amount of days for it)
- Client buyer address
- Payment reference
- Specific code
- Constant symbol
- Method of delivery
- Method of payment
- Currency
- Order items (with their final price after applying promotion and tax adjustments)
- Shipping adjustment (with its final price applying shipping promotion and tax adjustments).

Note that if you use custom fees and other custom adjustments in your order, you have to add extra code to submit also those by subscribing to the superfaktura.invoice_pre_send event.

The development of this module is sponsored by Superfaktura.
