Connecting to 3-Corner Networks
Billing Service Provider (BSP) networks offer a centralized platform approach to electronic invoicing. Learn how to connect to 3-corner networks and leverage managed services for simplified multi-partner invoice exchange.
Understanding 3-Corner Networks
In a 3-corner model, a central platform provider facilitates all invoice exchanges between buyers and suppliers, offering a managed solution that simplifies connectivity and reduces technical complexity.
Unlike traditional EDI where each trading partner connection must be established separately, 3-corner networks provide a single point of integration. Once connected to the platform, you can immediately exchange invoices with all other participants on that network.
The BSP handles format conversions, delivery tracking, and technical infrastructure, allowing you to focus on your business processes rather than managing technical integrations.
Centralized Platform
Connect once to the BSP platform and gain immediate access to all network participants without establishing individual connections.
Managed Services
The BSP handles technical infrastructure, format conversions, monitoring, and support, reducing your operational burden and IT requirements.
Rapid Deployment
Faster implementation compared to traditional EDI, with standardized onboarding processes and pre-configured integrations for common ERP systems.
How 3-Corner Networks Function
Understanding the flow of invoices through a BSP platform helps clarify the roles and responsibilities of each party.
Invoice Creation
Supplier creates an invoice in their system (ERP, accounting software, or directly in the BSP portal) following standard business processes.
Platform Receipt
Invoice is transmitted to the BSP platform, which validates the data, checks recipient registration, and converts to the appropriate format if needed.
Central Processing
The BSP platform applies business rules, performs compliance checks, archives the invoice, and prepares it for delivery to the buyer.
Buyer Delivery
Platform delivers invoice to buyer's system in their preferred format (EDI, XML, PDF) or makes it available in the buyer's portal.
Status Tracking
Both parties receive delivery confirmations and can track invoice status through the platform's monitoring tools and notifications.
Archive & Reporting
BSP maintains legally compliant archives of all transactions and provides reporting capabilities for both suppliers and buyers.
Ways to Connect to BSP Platforms
BSP networks offer multiple connection methods to accommodate different technical capabilities and business requirements.
API Integration
Direct system-to-system integration via REST APIs. Ideal for organizations with development resources, enabling automated invoice submission and retrieval.
ERP Connector
Pre-built connectors for major ERP systems (SAP, Oracle, Microsoft Dynamics). Plug-and-play integration with minimal custom development required.
File Upload
Batch upload of invoices via SFTP or web interface. Suitable for mid-volume scenarios where real-time integration isn't critical.
Web Portal
Browser-based interface for manual invoice entry and management. Perfect for low-volume suppliers or as a backup to automated methods.
Email Gateway
Send invoices via email to a dedicated address where the BSP extracts and processes them. Convenient for smaller suppliers with limited IT resources.
Hybrid Approaches
Combine multiple methods: API for high-volume partners, portal for occasional suppliers. Flexibility to match different supplier capabilities.
BSP Network Onboarding Process
Most BSP providers follow a standardized onboarding workflow designed to get you connected quickly and efficiently.
Typical Onboarding Timeline
Standard onboarding for 3-corner networks typically takes 2-6 weeks, depending on integration complexity and your internal processes. Portal-only access can be activated within days, while full API integration may require more extensive testing and configuration.
Registration & Setup
Complete registration forms, provide company details, define user roles and permissions, and configure basic account settings.
Documentation Review
Study integration specifications, API documentation, data format requirements, and understand available services and features.
Technical Configuration
Install connectors or develop API integration, configure mapping rules, set up routing logic, and establish secure connections.
Testing & Validation
Send test invoices, verify data accuracy, validate delivery to recipients, and confirm error handling and exception management.
User Training
Train staff on portal usage, reporting tools, exception handling, and best practices. Many BSPs provide comprehensive training materials and support.
Production Activation
Switch to production environment, begin processing live invoices, monitor initial transactions closely, and optimize based on real-world performance.
Benefits & Considerations
Understand the advantages of 3-corner networks and key factors to consider when selecting a BSP provider.
Lower Initial Investment
Reduced upfront costs compared to building EDI infrastructure. Subscription-based pricing with predictable monthly fees.
Faster Time to Value
Quicker deployment than traditional EDI. Access to existing network participants immediately upon connection.
Simplified Management
BSP handles infrastructure maintenance, updates, and support. Less internal IT resource requirement compared to self-managed solutions.
Network Effects
Value increases as more trading partners join the platform. Larger BSPs offer access to extensive participant directories.
Limited Interoperability
Can only exchange with participants on the same BSP platform. May require connections to multiple BSPs for full trading partner coverage.
Vendor Lock-in
Switching BSPs can be complex once established. Evaluate long-term viability and exit strategies before committing to a platform.
