Ecuador SRI Electronic Invoicing
Factura, Nota de Credito & Comprobante de Retencion — SRI Offline Scheme v2.32
Issue, digitally sign and authorize Ecuadorian comprobantes electronicos directly from Odoo through the SRI (Servicio de Rentas Internas) offline scheme, following ficha tecnica v2.32 (Nov-2025). Built on a shared e-invoicing engine and compatible with Odoo 18 and 19.
Native SRI Documents
Generates the real SRI XML schemas — factura 2.1.0, notaCredito 1.1.0 and comprobanteRetencion 2.0.0 — not generic UBL. Every field SRI expects (infoTributaria, infoFactura, detalles, totalConImpuestos) is produced correctly.
49-Digit Access Key
Builds the clave de acceso with the official modulo-11 check-digit algorithm: date, document type, RUC, environment, establishment / emission point, sequential, numeric code and emission type — all assembled and verified automatically.
Real RUC & Cedula Validation
The exact SRI check-digit rules: modulo-10 for cedula and natural-person RUC, modulo-11 (coefficients 3-2 and 4-3-2) for public and private RUC. The buyer identification type (tipoIdentificacionComprador) is detected automatically.
BYOK XAdES Signing
Comprobantes are sealed with an enveloped XAdES-style signature using your own X.509 certificate (PEM). The certificate is stored only on your database and never transmitted — pure bring-your-own-key.
Reception & Authorization
Submits to the SRI RecepcionComprobantesOffline service and polls AutorizacionComprobantesOffline for the asynchronous AUTORIZADO state. Retry, backoff and full request/response logging are built in; endpoints default to the documented SRI celcer/cel URLs and remain editable.
QR & Verification Reference
Produces the access-key verification QR pointing at the SRI public consultation portal, ready for the printed RIDE.

Disclosure
This module transmits the signed comprobante XML to the SRI reception and authorization endpoints you configure (or their documented defaults). No data is sent anywhere else, and your signing certificate is stored only on your own database.
