Variables

Here the features of the variables of the Fatoora class will be explained

• Seller’s name.
• Seller’ tax number, which is the VAT registration number.
• Invoice date, which is the timestamp of the electronic invoice.
• Invoice total amount, which is the electronic invoice total with VAT.
• Tax amount, which is the VAT total.

Name	Feature	How will it be in the tag	How will it be when you call
seller_name	saved directly without processing	No changes will be made to it	No changes will be made to it
tax_number	receives the tax number as a text and a number as well, and save it as string	number as string	number as string
invoice_date	receives the date as timestamp or datetime object, or string ISO 8601 Zulu format	string of date as ISO 8601 Zulu format	datetime object
total_amount	receives the tax number as a text and a number as well	It is of type str as float	It is of type float
tax_amount	same total_amount + Accept None value to get VAT auto from total_amount	same total_amount	same total_amount

Note: The tax_amount is rounded to the nearest two decimal places, if it is greater than that ( if tax_amount == 15 its will be 15.0)

Note: If you set tax_amount to None the vat_rates == 0.15 you can change it in Fatoora object

Generate Base64

from fatoora import Fatoora

fatoora_obj = Fatoora(
    seller_name="Awiteb",
    tax_number=1234567891, # or "1234567891"
    invoice_date=1635872693.3186214, # timestamp or datetime object, or string ISO 8601 Zulu format
    total_amount=100, # or 100.0, 100.00, "100.0", "100.00"
    tax_amount=15, # or 15.0, 15.00, "15.0", "15.00"
)

print(fatoora_obj.base64)
# AQZBd2l0ZWICCjEyMzQ1Njc4OTEDFDIwMjEtMTEtMDJUMTc6MDQ6NTNaBAUxMDAuMAUEMTUuMA==

Render A QR Code Image

You can render the tags as QR code image easily

The content is the base64 of the invoice

from fatoora import Fatoora

fatoora_obj = Fatoora(
    seller_name="Awiteb",
    tax_number=1234567891,
    invoice_date=1635872693.3186214,
    total_amount=100,
    tax_amount=15,
)

fatoora_obj.qrcode("qr_code.png")

The content is the invoice url

from fatoora import Fatoora

fatoora_obj = Fatoora(
    seller_name="Awiteb",
    tax_number=1234567891,
    invoice_date=1635872693.3186214,
    total_amount=100,
    tax_amount=15,
    qrcode_url="https://example.com"
)

fatoora_obj.qrcode("qr_code_with_url.png")

Generate hash (sha256)

from fatoora import Fatoora

fatoora_obj = Fatoora(
    seller_name="Awiteb",
    tax_number=1234567891, 
    invoice_date=1635872693.3186214,
    total_amount=100, 
    tax_amount=15, 
)

print(fatoora_obj.hash)
# 20b8ddb6ed9cb98be3d8535a1f4f28e35888842c1b0aed0e90c3e7fb51080dd9

Read qr code

from fatoora import Fatoora

fatoora_obj = Fatoora(
    seller_name="Awiteb",
    tax_number=1234567891, 
    invoice_date=1635872693.3186214,
    total_amount=100, 
    tax_amount=15, 
)

fatoora_obj.qrcode("qr_code.png")

print(Fatoora.read_qrcode("qr_code.png", dct=True))
# {'seller_name': 'Awiteb', 'tax_number': '1234567891', 'invoice_date': '2021-11-02T17:04:53Z', 'total_amount': '100.0', 'tax_amount': '15.0'}

print(Fatoora.read_qrcode("qr_code.png", dct=False))
