SIFEN guides

Three ways to integrate with SIFEN, a single issuance.

Choose how your company issues electronic documents through ECAV. All three talk to the same gateway and end up authorized by the DNIT.

Integration paths

How do you issue today?

Via Odoo

You issue from your ERP: invoice as always, and ECAV's module signs, sends and reconciles with the DNIT in the background. This is the path all five of ECAV's production tenants use today.

Módulos: ecav_sifen_client + l10n_einvoice/l10n_einvoice_py.

Via direct API

If your system isn't Odoo, integrate directly against ECAV's gateway: JWT authentication and end-to-end encrypted data (AES-256-GCM). Built for in-house or third-party ERPs.

Librería cliente: ecav_api_client, contra ecav_sifen_service.

Via standalone

Sin ERP propio: emitís desde el portal facturas.ecav.com.py. Hoy permite emitir, consultar y descargar XML/KuDE de tus documentos. Todavía no tiene una acción de cancelar o inutilizar -- solo muestra ese estado si ya ocurrió; para cancelar un documento, escribinos a soporte@ecav.com.py.

Perfil interno: standalone_ui.
