Overview

Varibill is continuing the transition from Varibill Classic (Legacy) to the Varibill User Interface as part of an ongoing platform modernization initiative focused on:

• Operational scalability
• Improved performance
• Modernized infrastructure
• Long-term platform sustainability

Over the past several years, significant operational workflows and infrastructure components have already transitioned to the Varibill User Interface platform.

The next phase of this initiative includes continued modernization of:

• Billing and validation workflows
• Source Collector architecture
• Integration methods
• Operational usability
• Platform scalability

This article provides an overview of:

• What is changing
• What customers should expect
• How Varibill will support customers throughout the transition process

Why This Change Is Happening

The original Varibill Classic platform has supported customers successfully for many years. As the platform has grown, portions of the underlying architecture are approaching the limits of long-term scalability and maintainability.

The Varibill User Interface introduces:

• Improved operational performance
• Enhanced scalability
• Modernized infrastructure
• Improved usability
• Improved search responsiveness
• A flexible foundation for future development

This modernization initiative is designed to:

• Improve operational efficiency
• Support larger environments and datasets
• Simplify future platform enhancements
• Provide a stronger long-term operational foundation

Current Improvement Focus Areas

Current platform enhancements include:

• Improved large dataset usability
• Enhanced search responsiveness
• Improved filtering and lookup behaviour
• Operational workflow modernization
• Infrastructure scalability improvements
• Ongoing usability enhancements within the Varibill User Interface

These improvements are particularly important for customers operating within:

• High transaction-volume environments
• Complex billing environments
• Large operational datasets

Planned Migration Roadmap

Source Collector Platform Changes

Varibill is modernizing the Source Collector platform and ingestion architecture.

As part of this transition:

• Older Source Collector formats will progressively transition to newer supported standards
• Newer ingestion methods and APIs will become the supported long-term platform direction
• Customers using custom or older integrations may require migration planning activities

Customers using:

• Custom Source Collectors
• Direct ingestion integrations
• Specialized operational workflows

may be contacted directly where migration planning or compatibility validation is required.

Source Collector API Modernization

Older Source Collector ingestion methods are progressively being replaced with a newer REST-based API architecture.

The new API platform supports:

• Improved scalability
• Modern authentication
• Structured payload handling
• Improved validation
• Future extensibility

Additional migration guidance and technical documentation will be published separately, including:

• Configuration guidance
• Authentication guidance
• Payload examples
• API documentation
• Migration assistance material

What Customers Should Expect

Customers can expect:

• Progressive migration communication
• Advance notice before major changes
• Staging/testing opportunities where applicable
• Migration guidance documentation
• Compatibility review where required
• Ongoing support during transition activities

Varibill will continue prioritizing operational continuity throughout the migration process.

What Customers May Need To Do

Depending on current platform usage, Varibill may work with customers to:

• Review Source Collector implementations
• Validate integration compatibility
• Assist with migration planning
• Test updated ingestion methods
• Validate workflows within staging environments
• Coordinate operational transition activities

Compatibility Notice

Some older integrations, custom ingestion methods, or legacy operational workflows may require review and migration activities to ensure compatibility with the evolving platform architecture.

Varibill will provide guidance and support for impacted customers throughout the transition process.
