Direct SIFEN (Sistema Integrado de Facturación Electrónica Nacional) connector for Paraguay electronic invoicing.

This module extends the generic EDI connector from l10n_py_edi_base to provide direct transmission to SIFEN using the pysifen library, without intermediary services like FactPy or FacturaSend.

Features:

  • Direct SOAP/mTLS communication with SIFEN
  • Digital signature via PKCS12 certificate
  • RDe (Documento Electrónico) building from invoice data
  • Support for FE, NCE, NDE, NRE, AFE document types
  • Test and Production environment support

AI-generated from the code · Odoo 20.0

Connect Odoo directly to Paraguay's SIFEN electronic invoicing service using your own digital certificate. Send, consult, cancel and void electronic documents, and generate the QR code, without any intermediary provider.

This module adds a "SIFEN Directo" option to the electronic invoicing connector, so Paraguayan companies can transmit electronic documents straight to the tax authority (SET) instead of going through a third-party service.

  • On the company form, a "Certificado Digital (SIFEN)" section lets you upload your PKCS12 (.pfx) certificate, its password and see its expiry date. This certificate is required for the secure connection.
  • On the EDI connector form, a SIFEN section asks for the CSC and ID CSC codes given by the SET (these differ between test and production).
  • The connector can send documents, check their status, cancel them, void number ranges, preview the document and preview the QR code, and test the connection.
  • Documents are built for the SIFEN v150 format, covering invoices, credit and debit notes, remittance notes and self-invoices, with items, taxes, payment conditions, transport and associated documents.
  • The QR code is generated from the signed document and injected into the file; if the CSC is missing, the QR is skipped.
  • A successful connection test shows a notification; connection errors raise a message.

It extends the l10n_py.edi.connector and res.company models.
