As of January 1, 2026, one of the most important electronic invoicing reforms in years took effect in Ecuador: immediate transmission of receipts to the Servicio de Rentas Internas (SRI). If your company issues invoices, withholding receipts, or complementary documents, this change affects you directly.

What does the new rule say?

The obligation comes from Resolution No. NAC-DGERCGC25-00000014 (issued June 30, 2025) and its amendment under Resolution No. 17 (July 30, 2025). The core change: the prior window of up to 4 business days to transmit electronic receipts was removed. Transmission must now be immediate, in real time, at the moment of issuance.

In addition, the receipt date must match the actual operation date, and voiding invoices issued to final consumers is prohibited from January 1, 2026.

What does 'immediate transmission' mean in practice?

  • Every invoice, withholding receipt, credit note, debit note, and shipping guide must be sent to the SRI the moment it is issued.
  • You can no longer batch receipts to send them at end of day or within the following days.
  • Your invoicing system needs an online connection and SRI response to authorize the receipt almost instantly.
  • Offline schemes still exist as a contingency, but the general rule is immediate transmission.

How to adapt your operation and software

The biggest risk lies in systems that invoice in batches or rely on manual processes. If your company issues many receipts per day, your SRI integration must be automatic, with retries on network errors and monitoring of receipts left unauthorized.

  1. Make sure your electronic signature is valid and your RUC is active.
  2. Confirm your invoicing software transmits at issuance, not in deferred batches.
  3. Implement automatic retries and alerts for unauthorized receipts.
  4. Keep a dashboard with the status of each receipt (authorized, rejected, in process).
  5. Define a contingency protocol (offline scheme) for connection outages.

At RoxiumLabs we build custom platforms that integrate electronic invoicing with the company's daily operation: bulk document upload, secure storage, status control, and direct SRI connection. It is the kind of problem we solved for an accounting firm managing multiple clients.
