fiskal-hr 0.9.1

Client for Croatian Fiskalizacija tax service

fiskal-hr

Python 3 package for integrating with Croatian tax authority Fiskalizacija service.

Scope

The package provides full integration with the Fiskalizacija service, including:

• checking invoice details in test (DEMO) mode - FiskalClient.check_invoice()
• submitting an invoice - FiskalClient.submit_invoice()
• submitting a fiscalization document - FiskalClient.submit_document()
• changing the payment method - FiskalClient.change_payment_method()

Requirements

You'll need your client certificate, Fiskalizacija service certificate and FINA root CA certificates. Read the integration guide for detailed steps how to get and prepare the certificates.

You'll also need the libxmlsec1 library installed on your computer.

Quickstart

1. Install fiskal-hr:

   pip install fiskal-hr
   

2. Make sure you have your certificates ready, then initialize the fiskal client package:

   from fiskalhr.invoice import Invoice
   from fiskalhr.ws import FiskalClient
   from fiskalhr.signature import Signer, Verifier
   
   signer = Signer("path/to/your-client-cert.pem")  # if encrypted, you'll need the password as well
   verifier = Verifier("path/to/service-cert.pem", ["path/to/fina-demo-ca-combined.pem"])
   fiskal_client = FiskalClient(
       "path/to/fina-demo-ca-combined.pem",
       "path/to/wsdl/FiskalizacijaService.wsdl",
       signer,
       verifier,
   )
   

3. Check communication with the service:

   fiskal_client.test_service()
   

   This sends a "ping" message to the echo service, to check that basic connectivity is working. If there's an error, the test_service() method will raise an exception.

4. Create a test invoice and ask the service to do sanity checks on it (this only works in the demo mode):

   invoice = Invoice(fiskal_client, oib="YOUR-OIB", invoice_number="1/X/1", total=100)
   
   fiskal_client.check_invoice(invoice)
   

   If there are any errors, the check_invoice() method will raise fiskalhr.ResponseError with the error details in the details attribute.

   Note that this does only basic sanity checking. For example, it will not check if the point of sale location (code X in the invoice number in this example) is registered.

Testing

This package has 100% unit test coverage. To run the tests:

pytest

Coverage report is generated automatically. To export it in HTML form, run coverage html.

The tests do not contact Fiskalizacija service or any other external service, nor do they require actual certificates. They are entirely self-contained.

More info about testing and certificates is available in the testing guide.

Contributing

Found a bug or think something can be improved? All contributions are welcome!

Before changing any code, please open a GitHub issue explaining what you'd like to do. This will ensure that your planned contribution fits well with the rest of the package and minimize the chance your pull request will be rejected.

If changing any code, please ensure that after your changes:

• all tests pass and the code coverage is still 100%
• black, flake8 and isort find no problems
• the code doesn't depend on any external service
