Electronic Invoicing in Portugal 2025

Complete guide on implementation and legal compliance

Electronic invoicing represents a fundamental transformation in the way companies and public bodies manage their administrative and financial processes. In Portugal, this reality has become even more relevant with the application of European regulations that establish strict standards for the issuance, transmission, and receipt of electronic documents.

Interoperability and integration with external systems

Interoperability is a fundamental aspect of modern electronic invoicing. The ilink platform is interconnected with all operators in the Portuguese market, allowing the exchange of documents between different EDI networks.

Integration with external invoicing and accounting systems is carried out via APIs and specific technical documentation. These integrations allow the invoicing process to be fully automated, from document creation to sending and status tracking.

The expansion of interoperability to European markets is under constant development by ilink, although each market is subject to specific electronic invoicing standards that must be validated individually.
