SaudiEInvoice is a Python library that helps you create and submit invoices to the Saudi Arabian General Authority of Zakat and Tax (GAZT) using the e-invoicing system.

Before using SaudiEInvoice, you need to have the following:

• Python 3.6 or higher
• OpenSSL library
• A GAZT account
• A valid private key file (.pfx format) and its password
• An e-invoicing API URL provided by GAZT

To install SaudiEInvoice, you can simply clone this repo.

To use SaudiEInvoice, you need to create an instance of the SaudiEInvoice class and provide it with the path to a configuration file that contains your GAZT account credentials, private key file path, and the e-invoicing API URL.

from saudieinvoice import SaudiEInvoice
sei = SaudiEInvoice(config_file_path="config.json")

To create an invoice, you can pass an invoice data dictionary to the create_invoice() method. The dictionary should contain the invoice number, invoice date, vendor name, customer name, and a list of line items.

invoice_data = {
    "invoice_number": 123,
    "invoice_date": "02/10/2023",
    "vendor": "example co.",
    "customer": "example customer",
    "line_items": [
        {"product": "product1", "quantity": 1, "price": 20, "total": 20}
    ]
}

encoded_invoice_data = sei.create_invoice(invoice_data)

To submit an invoice, you can pass the encoded invoice data to the send_invoice() method.

success = sei.send_invoice(encoded_invoice_data)

if success:
    print("Invoice submitted successfully!")
else:
    print("Failed to submit invoice.")

To save the generated XML invoice to a file, you can use the built-in ElementTree library in Python.

import xml.etree.ElementTree as ETroot = ET.fromstring(encoded_invoice_data)
xml_invoice = ET.tostring(root, encoding="utf-8")with open("invoice.xml", "wb") as f:
    f.write(xml_invoice)
