Peppol Access Point Microservice for Enterprise E-Invoicing
For a global consulting firm, we implemented a Peppol Access Point microservice to securely send and receive e-invoices. Using Java, Spring Boot, AS4, SMP/SML, Docker, and Kubernetes, the solution ensures full Peppol compliance and seamless integration with enterprise systems. The client now achieves reliable, automated invoice exchange, reducing manual effort and meeting international e-invoicing standards.
Background and Objectives
Our client, a global consulting firm, aimed to expand its e-invoicing capabilities by enabling secure, fully compliant electronic invoice exchange via the Peppol network. The primary objective of the project was to design and implement a Peppol Access Point microservice that allows sending and receiving e-invoices while fully adhering to Peppol and AS4 standards.
Key requirements included:
- Full compliance with Peppol specifications and security standards
- Seamless integration with the client’s existing systems and infrastructure
- High interoperability with external partners on the Peppol network
- A scalable, robust, and easily maintainable architecture suitable for enterprise use
Our Solution
We designed and developed a dedicated Peppol Access Point microservice that enables secure and reliable e-invoice exchange over the Peppol network.
The solution included the following core components:
- SMP/SML integration for dynamic participant and endpoint discovery
- Message validation to ensure compliance with Peppol document and business rules
- Digital signing and encryption to guarantee data integrity and security
- AS4-compliant message transmission and reception
- Seamless system integration with the client’s existing internal platforms
Throughout the implementation, special emphasis was placed on reliability, automated error handling, and operational transparency, significantly reducing the need for manual intervention.
Results and Business Impact
As a result of the project:
- Fully compliant Peppol message exchange was achieved with a 100% success rate in production
- Manual processing efforts and error rates were significantly reduced
- Data transmission reliability, performance, and overall system stability were improved
- The solution integrated smoothly into the client’s existing infrastructure
The project was successfully completed, and all official Peppol compliance tests were passed with a 100% success rate, enabling the client to offer a robust, scalable, and future-proof e-invoicing solution aligned with international standards.
