Digital carrier billing
Standardized integrations across multiple aggregators and orchestrated billing and provisioning with centralized error handling.
ROS
The execution engine Korzail uses to run assured processes end to end
Most enterprise processes do not fail in one dramatic moment. They break in the gaps between systems. CRM says activated. Billing does not converge. Provisioning only partially completes. Partners stall. Teams are left reconciling what really happened.
ROS closes that gap. It runs the process itself across APIs, events, queues, files, and databases with preserved state, step-level traceability, and defined handling when things go wrong. Every run produces an outcome you can trust, a trace you can follow, and the control needed to stop the same failure from repeating.
Built for complex cross‑system and long‑running operations
Preserved state with restart, recovery, and compensation
Step‑level traceability tied to the business entity
Deterministic error handling that supports correction paths
Deployed in your environment and aligned to your security model
What ROS Is
ROS is the execution layer turns a company's business process into an Assured Process that runs end to end across existing systems.
Execution Assurance needs control, not just visibility
Many tools can connect systems or run steps. The hard part is keeping ownership of completion when a process spans systems, time gaps, asynchronous events, and failure.
Understand ROS in four building blocks
FLOW
01A FLOW is the executable representation of a business process. It defines the sequence of steps that run across systems.
STEP
02A STEP is one unit of execution inside a FLOW. Steps can run in sequence or, when safe, in parallel.
ACTION
03An ACTION is the work performed inside a STEP. It calls systems, applies rules, or handles data inside the process.
LOADER
04A LOADER starts execution when systems cannot call an API directly or when high-volume ingestion is needed.
Connect any system. Trigger execution from anywhere
ROS is built for real enterprise environments that mix modern APIs, legacy interfaces, events, queues, files, and database-driven patterns.
What this means in practice
If the process needs an adapter, endpoint, or service layer that does not yet exist, ROS can provide it so execution does not stop at the system boundary.
Integration through:
- REST APIs
- SOAP web services
- Database reads and writes
- Event streams and topics
- Message queues
Flows can be invoked:
- API calls
- Events and topics
- Queues
- File drops
- Database table triggers
How a process runs in ROS
From trigger to declared outcome, ROS executes the process as one stateful thread, coordinates each step across systems, verifies completion, and records what happened.

Run long-running operations with preserved state and controlled recovery.
Enterprise operations span systems without one shared transaction boundary. ROS is built for that reality.
ROS coordinates multi-system execution with:
Execution Assurance controls
Preserved state and controlled recovery.
- Preserved state across steps and time
- Ordered execution across systems
- Structured recovery when errors occur
- Resume from the last safe point
- Compensation patterns when rollback is required
What this avoids
Failure patterns that leave work unfinished.
- Brittle point-to-point chains
- Unclear ownership when execution fails
- Exception queues as the default operating model
- Log stitching as the primary troubleshooting method
- Manual reconciliation as the path to completion
Stop guessing. See exactly what happened
ROS treats traceability as a first-class execution requirement.
- What happened in this execution instance
- Which system interactions occurred
- Which step succeeded or failed
- What data and conditions were present at failure time
Deterministic control when execution breaks
ROS supports:
- Timed retries
- Controlled reprocessing
- Step bypass logic
- Cancellation when needed
- Error classification by context
- Runaway retry protection
ROS error handling can be configured by specifying:
- Where the error occurs
- What the error is
- How it should be handled
- When the correction should run
This is the mechanism that enables correction paths. When a failure mode is understood, it can be encoded into the execution model so the same failure does not repeat under the same conditions.
High throughput without losing control
Some operations are not single instances. They are migrations, bulk adjustments, regulatory windows, and high-frequency operational flows. ROS is built to execute them at scale without sacrificing visibility or control.
ROS supports bulk execution with:
- Ingestion through loaders that pull from tables, files, topics, and queues
- Batching and parallel execution controls for throughput
- Progress visibility during execution windows
- Guardrails that protect downstream systems during degraded conditions
A stable process layer that survives system replacement.
Assured execution breaks when business logic is embedded inside each system.
When business logic lives inside each system, every replacement becomes a rebuild.
What this enables
Coexistence during old and new system migrations safely
Phased cutovers without operational disruption to customers
Resilience when interfaces, data models, and vendors change
Runs in your environment and aligns to your controls
ROS is designed to run inside customer environments and align with security, compliance, and governance requirements.
- Containerized runtime aligned to modern infrastructure standards
- On-prem or cloud deployment aligned to your operating model
- Vendor neutral integration across systems
- Coexistence with existing tools when it makes sense
Why ROS is more than integration or workflow orchestration.
Most tools connect systems or run steps. ROS is built to execute the full process with state, traceability, and controlled recovery.
| What matters for Assured Execution | Typical tools and approaches | ROS |
|---|---|---|
| Final-state verification | Not inherent | Built in |
| Preserved state and restart | Limited or variable | Native |
| Failure handling and recovery | Basic or custom | Structured |
| Traceability per execution | Partial or tool-local | Step-level across systems |
| Hybrid, synchronous, and asynchronous execution | Sometimes | Designed for both |
| Change resilience during system change | Rebuild-heavy | Stable process layer |
| Improvement over time | Manual rework and tickets | Correction paths in the model |
Execution Assurance is the discipline. ROS is the execution layer that makes it operational.
ROS in production
A few examples of how ROS has solved complex operator challenges in production.
On-demand billing migration
Automated customer and service migration between billing platforms while keeping data synchronized and avoiding disruption.
Bulk collections and reactivation
Moved high-volume suspensions and reactivations into ROS and removed performance bottlenecks that blocked go-live.
Salesforce integration
Unblocked a multi-year vendor deadlock and achieved end-to-end activation by using ROS as the service layer between CRM, billing, charging, and provisioning.
Portability
Migrated the portability lifecycle into ROS and eliminated recurring regulator fines.
Prepaid top-up
Improved execution speed and traceability and reduced losses by stabilizing top-up execution and reconciliation.
Layer decoupler
Moved core processes into ROS as a stable process layer so front ends and back ends could evolve independently.
Hot migration
Automated plan-change triggered migrations between billing platforms with validation, mapping, and error handling.
Notification engine
Centralized outbound notifications with delivery windows, throttling, and multi-channel orchestration.
System coexistence during migration
Synchronized financial objects across two systems using hybrid synchronous and asynchronous patterns during phased cutover.
Real-time upsell
Connected network events to rules-based routing and partner integration with sub-second response requirements.
Bulk rate plan price increase
Executed a time-windowed regulatory update using parallel batch processing and progress visibility.

FAQs
Is ROS just an orchestration platform?
No. ROS includes orchestration and integration capabilities, but it is designed as an execution layer with preserved state, step-level traceability, deterministic error handling, and recovery patterns that support assured completion.
Do we still need our existing integration tools?
Not necessarily for the processes you want to assure. ROS can run those processes end to end and coexist with other platforms where they still serve the business.
Why not rely only on event choreography and microservices?
Choreography works well for simpler interactions. When a process spans systems, time gaps, asynchronous events, and failure, ROS provides the central control, preserved state, and traceability needed to keep completion accountable.
