This is library to generate a simple invoices. Currently supported formats are PDF and XML for Pohoda accounting system. PDF invoice is based on ReportLab.
Run this command as root:
pip install InvoiceGenerator
If you want upgrade to new version, add --upgrade flag:
pip install InvoiceGenerator --upgrade
You can use setup.py from GitHub repository too:
python setup.py install
Complete documentation is available on Read The Docs.
Define invoice data first:
import os
from tempfile import NamedTemporaryFile
from InvoiceGenerator.api import Invoice, Item, Client, Provider, Creator
# choose english as language
os.environ["INVOICE_LANG"] = "en"
client = Client('Client company')
provider = Provider('My company', bank_account='2600420569', bank_code='2010')
creator = Creator('John Doe')
invoice = Invoice(client, provider, creator)
invoice.currency_locale = 'en_US.UTF-8'
invoice.add_item(Item(32, 600, description="Item 1"))
invoice.add_item(Item(60, 50, description="Item 2", tax=21))
invoice.add_item(Item(50, 60, description="Item 3", tax=0))
invoice.add_item(Item(5, 600, description="Item 4", tax=15))
Note: Due to Python's representational error, write numbers as integer tax=10,
Decimal tax=Decimal('10.1') or string tax='1.2' to avoid getting results with
lot of decimal places.
Generate PDF invoice file:
from InvoiceGenerator.pdf import SimpleInvoice
pdf = SimpleInvoice(invoice)
pdf.gen("invoice.pdf", generate_qr_code=True)
Generate XML invoice file:
from InvoiceGenerator.pohoda import SimpleInvoice
pdf = SimpleInvoice(invoice)
pdf.gen("invoice.xml")
Note: Pohoda uses three tax rates: none: 0%, low: 15%, high: 21%. If any item doesn't meet those percentage, the rateVat parameter will not be set for those items resulting in 0% tax rate.
Only SimpleInvoice is currently supported for Pohoda XML format.
