Deep Blue designed and deployed a deterministic, PCI-compliant payment automation solution – eliminating live-agent involvement in routine payment calls while preserving a predictable voice experience.
Automating payments without compromising compliance
Challenge
Advanced Financial’s legacy contact center required live agents to handle a high volume of routine payment calls – creating significant operational cost while expanding PCI compliance exposure across every transaction.
Sensitive card data was handled directly by agents, increasing risk. Any automation needed to remain deterministic, predictable, and error-tolerant to meet strict security requirements.
Advanced Financial needed a partner who could evaluate AI capabilities with architectural judgment, make deliberate technology selections for PCI-sensitive workloads, and deliver a production-ready solution without rework.
- High agent cost on repeatable payment transactions
- Expanded PCI exposure with card data handled by agents
- No safe path to automate payments under compliance constraints
- Risk of unpredictable behavior from generative IVR approaches
Solution: End-to-End Payment Automation Stack
Deep Blue designed and implemented the payment automation solution end-to-end, including IVR flow design, Amazon Lex intent modeling, deterministic error handling, and voice experience refinement – integrated with Advanced Financial’s existing authentication and payment APIs.
What we built
- IVR flow design & call routing
- Amazon Lex intent modeling
- Deterministic error handling
- Voice experience refinement
- Authentication & payment API integration
- Structured prompts, confirms & retry logic
Why Deterministic Over Generative
Architectural Judgment
Generative IVR approaches – including Amazon NovaSonic – were evaluated and intentionally deselected for this phase due to early-release instability and unacceptable risk for PCI-sensitive payment flows. This was a deliberate architectural decision, not a dismissal of generative voice capabilities.
Future-Ready Foundation
Advanced Financial and Deep Blue are actively planning to introduce NovaSonic in future phases for use cases where conversational flexibility is appropriate and compliance constraints permit a generative approach. The validated solution is designed for direct promotion to production without architectural modification.
Results
Outcomes & Validation
Payment automation validated: IVR-based payment processing demonstrated that routine payment transactions can be completed without live agent involvement, directly reducing agent workload and operational cost.
PCI exposure reduced: Secure IVR flow eliminates sensitive payment data from live agent interactions, reducing PCI compliance scope.
The solution was validated against production-quality requirements throughout and is currently completing pre-production validation, with production deployment expected within the quarter.
- Payment automation validated end-to-end
- PCI compliance scope reduced
- Deterministic over generative — by design
- Production-ready without rework
- Future-ready for NovaSonic integration
