Understanding Access Points
The essential role Access Points play in the Peppol ecosystem and how they facilitate secure document exchange.
What is a Peppol Access Point?
A Peppol Access Point (AP) functions as your organization's entry point to the Peppol network infrastructure. These specialized service platforms manage the technical complexities of document transmission, allowing you to focus on your business operations rather than network protocols.
Think of an Access Point as a sophisticated postal service for digital business documents. Just as you trust a postal provider to deliver physical mail reliably and securely, an Access Point ensures your electronic invoices, purchase orders, and other business documents reach their intended recipients through the Peppol network.
Core Functions of Access Points
Access Points perform several critical functions that enable seamless Peppol communication:
Document Reception
Receives electronic documents from your business systems, validates format compliance, and prepares them for network transmission.
Validation & Compliance
Verifies documents meet Peppol BIS specifications, checks mandatory fields, and ensures syntactical correctness before transmission.
Routing & Delivery
Looks up recipient's Access Point in the SMP directory and routes documents securely using AS4 protocol with end-to-end encryption.
Status Reporting
Provides delivery confirmations, error notifications, and transmission logs for audit trails and troubleshooting purposes.
Document Archiving
Stores sent and received documents for statutory retention periods, typically 7-10 years depending on local regulations.
Security Management
Handles PKI certificates, manages encryption keys, and ensures secure authentication for all network communications.
Peppol operates on a "four-corner model": Corner 1 (your business) sends documents to Corner 2 (your Access Point), which transmits them to Corner 3 (recipient's Access Point), which delivers to Corner 4 (recipient's business). This architecture ensures interoperability while allowing organizations to choose their preferred Access Point provider.

Choosing the Right Access Point
Key criteria to evaluate when selecting your Peppol Access Point provider.
Essential Selection Criteria
Selecting the optimal Access Point requires careful evaluation of multiple factors aligned with your business requirements, technical infrastructure, and budget constraints.
Integration Capabilities
Verify compatibility with your existing systems. Does the provider offer plug-ins for your accounting software? API documentation quality? Support for your preferred protocols (REST, SOAP, SFTP)?
Pricing Structure
Compare total cost of ownership: monthly fees, per-document charges, setup costs, additional services. Consider your projected volume for accurate cost comparison. Watch for hidden fees.
Support Services
Assess support quality: response times, availability (24/7 vs business hours), channels (phone, email, chat), language support, technical expertise level, and implementation assistance.
Reliability & SLA
Review service level agreements: guaranteed uptime (aim for 99.5%+), maximum response times, compensation terms for outages, redundancy measures, and disaster recovery procedures.
Security & Compliance
Verify security certifications: ISO 27001, SOC 2, GDPR compliance. Data residency options, encryption standards, audit trail capabilities, and penetration testing frequency.
Scalability
Consider growth potential: can the platform handle volume increases? Are there tier upgrades available? Does pricing scale reasonably? Can you add users/locations easily?
Document Type Support
Confirm supported document types beyond invoices: purchase orders, order responses, despatch advices, catalogues. Check for additional formats like NLCIUS or country-specific variants.
Reporting & Analytics
Evaluate dashboard features: real-time monitoring, customizable reports, error tracking, volume statistics, partner analytics, and export capabilities for financial reconciliation.
Evaluation Process Checklist
- Define Requirements: Document your volume projections, technical environment, budget constraints, and must-have features
- Research Providers: Identify 5-7 certified providers operating in your region. Check their Peppol Authority standing
- Request Demos: Schedule product demonstrations with shortlisted providers. Test the user interface and integration processes
- Compare Proposals: Create a comparison matrix covering pricing, features, support, and contract terms
- Check References: Contact existing customers in your industry or size category for candid feedback
- Trial Period: If available, utilize free trial or pilot phase to validate compatibility and performance
- Review Contract: Carefully examine SLA terms, termination clauses, data ownership, and price escalation provisions
While all Access Points must meet minimum certification standards, service quality, feature sets, and customer support vary significantly. The cheapest option often lacks critical features or adequate support. Conversely, the most expensive doesn't guarantee the best fit. Focus on finding the right balance of capabilities, reliability, and value for your specific situation.
Technical Infrastructure & Standards
Understanding the technical architecture and protocols that power Peppol Access Points.
Core Technical Components
Access Points operate on standardized technical specifications ensuring interoperability across the global Peppol network. Understanding these components helps evaluate provider capabilities and integration requirements.
AS4 Transport Protocol
Mandatory since February 2020. AS4 (Applicability Statement 4) provides secure, reliable message exchange based on OASIS ebMS 3.0. Ensures guaranteed delivery, non-repudiation, and encrypted transmission between Access Points.
SMP (Service Metadata Publisher)
The directory service that enables recipient lookup. Each participant registers their Peppol ID and supported document types. Access Points query SMP to discover where to route documents for any given recipient.
PKI Infrastructure
Public Key Infrastructure manages digital certificates for Access Point authentication. Each certified AP receives a unique certificate from the Peppol PKI, enabling encrypted communication and ensuring sender authenticity.
Document Formats
Access Points process UBL 2.1 or UN/CEFACT CII formats compliant with EN 16931. Support for Peppol BIS (Business Interoperability Specifications) ensuring consistent structure across document types.
Validation Rules
Schematron validation rules enforce business logic and compliance. Access Points verify document structure, mandatory fields, code lists, and calculation accuracy before transmission to prevent rejection.
Identifier Schemes
Participant identification uses standardized schemes (ISO 6523). Examples: 0106 (Dutch KVK), 9944 (Dutch VAT), 0088 (GLN), 9925 (Belgian CBE). Access Points validate identifier format and routing accuracy.
Integration Methods
Access Points offer various integration approaches to accommodate different technical environments and business requirements:
REST/SOAP APIs
Programmatic integration for automated document exchange. RESTful APIs with JSON or SOAP web services with XML. Ideal for ERP/accounting system integration.
SFTP File Transfer
Batch processing via secure file transfer protocol. Upload files to designated directories, retrieve via scheduled polling. Suitable for legacy system integration.
Email Gateway
Send documents as email attachments to designated address. Access Point converts to Peppol format. Simplest method for low-volume users.
Web Portal
Browser-based interface for manual document upload/download. Includes validation tools, status tracking, and archiving. No technical integration required.
Certification & Compliance
How Access Points become certified and maintain compliance with Peppol standards.
The Certification Process
Becoming a certified Peppol Access Point requires rigorous testing and ongoing compliance monitoring by national Peppol Authorities. This ensures all Access Points meet consistent quality and security standards.
Path to Certification
- Application Submission: Provider applies to relevant Peppol Authority with business documentation and technical specifications
- Technical Review: Authority evaluates architecture, security measures, disaster recovery plans, and infrastructure capabilities
- Testing Phase: Mandatory connection to test environment. Verification of AS4 implementation, document validation, SMP integration, and error handling
- Conformance Testing: Automated test suite validates compliance with all Peppol specifications. Typical duration: 2-4 weeks
- Security Audit: Independent assessment of information security practices, encryption implementation, and access controls
- Certificate Issuance: Upon successful completion, provider receives PKI certificate and listing in official directory
- Production Go-Live: Access Point activates for production traffic. Initial monitoring period with Authority oversight
Ongoing Compliance Requirements
Certification isn't permanent—Access Points must maintain compliance through continuous monitoring and periodic re-certification:
Performance Monitoring
Peppol Authorities track uptime, delivery success rates, and response times. Providers must maintain 99.5% availability and report incidents promptly.
Transaction Reporting
Monthly submission of end-user statistics and transaction volumes to OpenPeppol. Aggregate data supports network planning and growth analysis.
Security Updates
Mandatory implementation of security patches and protocol updates. Providers must stay current with evolving Peppol specifications and vulnerability fixes.
Annual Re-certification
Yearly renewal process includes updated conformance testing, security audit review, and verification of continued compliance with all technical requirements.
The certification process ensures that every Access Point meets minimum standards for reliability, security, and interoperability. When choosing a provider, verify their certification status with your national Peppol Authority. Uncertified providers cannot legally operate as Peppol Access Points, and using them means you're not actually connected to the legitimate Peppol network.

- Bundle Services: Combining Access Point with other services (archiving, e-procurement) often yields discounts
- Negotiate Contracts: For 500+ documents/month, negotiate custom pricing rather than accepting standard rates
- Monitor Usage: Track actual consumption quarterly and adjust tier if consumption patterns change significantly
- Consider ROI: Focus on total value (support quality, features, reliability) not just lowest price per document
Beware of providers with exceptionally low advertised rates who charge extra for essentials: validation services, API access, webhook notifications, basic reporting, or reasonable support response times. Always request total cost breakdown for your projected usage scenario, including all necessary features. The truly cheapest provider often becomes expensive once you add required functionality.
